Introduction

Resource Aggregator for Open Distributed Infrastructure Management (ODIM™) is a modular, open framework for simplified management and orchestration of distributed physical infrastructure.

Resource Aggregator for ODIM comprises the following two key components:

The resource aggregation function (the resource aggregator):

The resource aggregation function is the single point of contact between the northbound clients and the southbound infrastructure. Its primary function is to build and maintain a central resource inventory. It exposes Redfish-compliant APIs to allow northbound infrastructure management systems to:
- Get a unified view of the southbound compute, local storage, and Ethernet switch fabrics available in the resource inventory
- Gather crucial configuration information about southbound resources
- Manipulate groups of resources in a single action
- Listen to similar events from multiple southbound resources
One or more plugins:

The plugins abstract, translate, and expose southbound resource information to the resource aggregator through RESTful APIs. Resource Aggregator for ODIM supports:
- Generic Redfish plugin for ODIM (The GRF plugin): This plugin can be used for any Redfish-compliant device
- Dell plugin for ODIM: Plugin for managing Dell servers
- Plugin for unmanaged racks (URP): This plugin acts as a resource manager for unmanaged racks.
- Cisco ACI plugin: Plugin for managing Cisco ACI servers
- Integration of additional third-party plugins
Resource Aggregator for ODIM allows third parties to easily develop and integrate their plugins into its framework. For more information, see Resource Aggregator for Open Distributed Infrastructure Management™ Plugin Developer's Guide.

Resource Aggregator for ODIM deployment overview

Deploying Resource Aggregator for ODIM in a data center involves installing the following microservices on one or more machines:

Kubernetes microservices
The resource aggregator microservices:
- API
- Account-session
- Aggregation
- Events
- Fabrics
- Managers
- Systems
- Tasks
- Update
- Telemetry
The plugin microservices such as the Dell plugin, URP, and additional third-party plugins
Third-party services such as Kafka, etcd, Zookeeper, and Redis

These microservices can be deployed as portable, light-weight Docker containers. The containerized services are orchestrated and managed by Kubernetes—an open-source container orchestration platform that helps to automate, scale, and manage a containerized application. For more information on Kubernetes and its architecture, see https://kubernetes.io/docs/home/.

The following diagram illustrates how Resource Aggregator for ODIM is deployed and used in a Kubernetes environment. It indicates a cluster with three controller nodes (Node 1, Node 2 and Node 3) and that any additional worker nodes can be added into the cluster.

To deploy Resource Aggregator for ODIM, you will require:

One virtual machine (VM) or a physical machine called the deployment node to deploy Kubernetes and Resource Aggregator for ODIM microservices. You can deploy the Resource Aggregator for ODIM microservices using the odim-controller command-line utility and use commands to:
- Set up the Docker environment
- Set up a Kubernetes cluster
- Deploy the containerized Resource Aggregator for ODIM microservices and third-party services on the Kubernetes cluster nodes
- Manage the Resource Aggregator for ODIM deployment
One or more physical or virtual machines called cluster nodes where the containerized Resource Aggregator for ODIM microservices and third-party services are deployed as pods. The cluster nodes include controller and additional worker nodes to share the extra load. The controller node in a cluster also functions as a worker node. A cluster can have either one or three controller nodes. A cluster with three controller nodes provides a High Availability (HA) environment. In addition, you can add worker nodes into the cluster to scale up the resources and the services.

Each controller node has the following components:
- An underlying Ubuntu OS platform
- The Docker container engine
- The resource aggregator and the plugin microservice pods
- The infrastructure pods containing all the third-party services
- Kubelet, Kubeproxy, and the Kubernetes control plane comprising the API server, Scheduler, and the Controller-Manager
For more information on these Kubernetes components, see https://kubernetes.io/docs/concepts/overview/components/.

The following diagram is a logical representation of each controller node in a Kubernetes cluster.

The northbound management and orchestration systems access the Resource Aggregator for ODIM services through a virtual IP address (VIP) configured on the Kubernetes cluster using Keepalived. Communication between Resource Aggregator for ODIM and the southbound infrastructure happens through the same VIP.

Nginx acts as a reverse-proxy for the cluster nodes. Keepalived and Nginx together help in implementing HA of the Resource Aggregator for ODIM services on the cluster nodes for both northbound management applications and southbound infrastructure to access.

Deployment considerations

Consider the following while deploying Resource Aggregator for ODIM:

A deployment node is required to deploy Kubernetes and Resource Aggregator for ODIM microservices.
The following two deployment configurations are supported:
- One-node cluster configuration: This configuration has only one cluster node that also functions as a worker node. It does not support scaling of the Resource Aggregator for ODIM resources and services—you cannot add worker nodes in a one-node cluster.
- Three-node cluster configuration: This configuration has three cluster nodes that also function as worker nodes for sharing the extra load. It provides HA environment by allowing the scaling of the Resource Aggregator for ODIM resources and services—you can add worker nodes and increase the number of service instances running in a three-node cluster.
To convert an existing one-node cluster into a three-node cluster, you must reset the one-node deployment first and then modify the required parameters in the odim-controller configuration file.

NOTE: Resetting the existing deployment clears all data related to it.
Controller nodes of a Kubernetes cluster must not be removed.
The GRF plugin is not meant to be used in a production environment. Use it as reference while developing third-party plugins.
Scaling of the third-party services—Kafka and Redis clusters is not supported.
There must be at least one instance of a resource aggregator service and a plugin service running in the cluster. The maximum number of instances of a resource aggregator service and a plugin service that are allowed to run in a cluster is 10.

Perform the following steps to install Helm package on the deployment node:
1. Create a directory called helm to store the Helm tool installation script and navigate to it.
```
mkdir ~/helm
```
```
cd ~/helm
```
2. Fetch the latest Helm installation script.
```
curl -fsSL -o get_helm.sh https://raw.githubusercontent.com/helm/helm/master/scripts/get-helm-3 | /bin/bash
```
3. Change permissions of the Helm installation script file.
```
chmod 0700 get_helm.sh
```
4. Run the Helm installation script.
```
/bin/bash get_helm.sh
```

Pulling the Docker images of all the Kubernetes microservices

Run the following command on the deployment node to pull each Docker image in the following table:

docker pull <imagename>:<version>

Example: docker pull quay.io/calico/cni:v3.19.2

The following table lists the details of all Docker images of the Kubernetes microservices to be pulled:

Docker image name	Version	Docker image file name
k8s.gcr.io/kube-apiserver	v1.21.5	k8s.gcr.io_kube-apiserver.tar
k8s.gcr.io/kube-controller-manager	v1.21.5	k8s.gcr.io_kube-controller-manager.tar
k8s.gcr.io/kube-proxy	v1.21.5	k8s.gcr.io_kube-proxy.tar
k8s.gcr.io/kube-scheduler	v1.21.5	k8s.gcr.io_kube-scheduler.tar
quay.io/calico/node	v3.19.2	quay.io_calico_node.tar
quay.io/calico/pod2daemon-flexvol	v3.19.2	quay.io_calico_pod2daemon-flexvol.tar
quay.io/calico/cni	v3.19.2	quay.io_calico_cni.tar
quay.io/calico/kube-controllers	v3.19.2	quay.io_calico_kube-controllers.tar
k8s.gcr.io/dns/k8s-dns-node-cache	1.17.1	k8s.gcr.io_dns_k8s-dns-node-cache.tar
k8s.gcr.io/pause	3.4.1	k8s.gcr.io_pause.tar
nginx	1.19	nginx.tar
k8s.gcr.io/coredns/coredns	v1.8.0	k8s.gcr.io_coredns_coredns.tar
quay.io/coreos/etcd	v3.4.13	quay.io_coreos_etcd.tar
k8s.gcr.io/cpa/cluster-proportional-autoscaler-amd64	1.8.3	k8s.gcr.io_cpa_cluster-proportional-autoscaler-amd64.tar
lachlanevenson/k8s-helm	v3.2.3	lachlanevenson_k8s-helm.tar

Verify the images are successfully pulled using the following command.
```
docker images
```
You get an output similar to the following sample:
Save each Docker image to a tar archive using the following command:
```
docker save -o <Docker image file name> <Docker image name>
```
Example: docker save -o quay.io_calico_node.tar quay.io/calico/node
Copy each saved tar archive to a directory called kubernetes_images on the deployment node.

For example:cp /home/bruce/*.tar /home/bruce/kubernetes_images

IMPORTANT: When deploying ODIMRA, update the 'kubernetesImagePath' parameter in 'kube_deploy_nodes.yaml' file with the path of the 'kubernetes_images' directory you choose in this step. The images are automatically installed on all cluster nodes after deployment.

The 'kube_deploy_nodes.yaml' file is the configuration file used by odim-controller to set up a Kubernetes cluster and to deploy the Resource Aggregator for ODIM services.

NOTE: Verify the permissions of the archived tar files of the Docker images; the privilege of all files must be 'user:docker'.

Building Docker images of all the services

Run the following commands on the deployment node:

git clone https://github.com/ODIM-Project/ODIM.git

```
cd ODIM
```
```
export ODIMRA_USER_ID=2021
```
```
export ODIMRA_GROUP_ID=2021
```
```
./build_images.sh
```
```
sudo docker images
```
If the images are built successfully, you get an output similar to the following sample:
Pull the reloader and busybox images using the following commands:
```
docker pull stakater/reloader:v0.0.76

docker pull busybox:1.33
```

Save all Docker images in the following table to a tar archive using the following command:

docker save -o <image_name.tar> <image_name>:<version>

Example: docker save -o api.tar api:3.0

Docker image name	Version	Docker image bundle name
account-session	3.0	account-session.tar
aggregation	3.0	aggregation.tar
api	3.0	api.tar
events	3.0	events.tar
fabrics	3.0	fabrics.tar
managers	3.0	managers.tar
systems	3.0	systems.tar
task	3.0	task.tar
update	3.0	update.tar
kafka	1.0	kafka.tar
zookeeper	1.0	zookeeper.tar
etcd	1.16	etcd.tar
redis	2.0	redis.tar
stakater/reloader	v0.0.76	stakater_reloader.tar
busybox	1.33	busybox.tar
dellplugin	2.0	dellplugin.tar
lenovoplugin	1.0	lenovoplugin.tar
urplugin	3.0	urplugin.tar
grfplugin	3.0	grfplugin.tar
telemetry	2.0	telemetry.tar

To install the Docker images of all services on the cluster nodes, create a directory called odimra_images on the deployment node and copy each tar archive to this directory. For example: cp /home/bruce/ODIM/*.tar /home/bruce/odimra_images

IMPORTANT: while deploying ODIMRA, update the 'odimraImagePath' parameter in 'kube_deploy_nodes.yaml' file with the path of the 'odimra_images' directory you choose in this step. The images are automatically installed on all cluster nodes after deployment.

NOTE: The 'kube_deploy_nodes.yaml' file is the configuration file used by odim-controller to set up a Kubernetes cluster and to deploy the Resource Aggregator for ODIM services.

Updating additional package versions

While deploying Resource Aggregator for ODIM, verify the versions of the following packages and update them if required.

Note: Verify the Keepalived and Nginx package versions only in case of a three-node cluster deployment.

linux-headers

Enter the following command:
```
sudo apt-cache madison linux-headers-5.8.0-63-generic
```
NOTE: If the above command fails with the error message, N: Unable to locate package linuxheaders- 5.8.0-63-generic, package version has changed. Proceed with further steps to find the latest version.

Enter the following command:

sudo apt-cache search --names-only "linux-headers-[0-9.-]*-generic" | tail -5 | sort -r

Enter the following command to verify if the first entry in the output list is present in the cache.
```
sudo apt-cache madison <package_name>
```
Example for <package_name> is linux-headers-5.8.0-63-generic
In case of a version mismatch, update the latest version of linux-header package in:

~/ODIM/odim-controller/odimra/group_vars/all/requirements.yaml

Keepalived

Enter the following command:
```
sudo apt-cache madison keepalived
```
Verify if the latest version is keepalived=1:2.0.19-2.
In case of a version mismatch, update the latest version of the Keepalived package in: ~/ODIM/odim-controller/odimra/group_vars/all/requirements.yaml

Nginx

Enter the following command:
```
sudo apt-cache madison nginx
```
Verify if the latest version is nginx=1.18.0-0ubuntu1.2.
In case of a version mismatch, update the latest version of the Nginx package in: ~/ODIM/odim-controller/odimra/group_vars/all/requirements.yaml

Generating an encrypted node password

Encrypting the password of the local non-root user on the Kubernetes cluster nodes makes the deployment process non-interactive. If the encrypted password is not available during deployment, you are prompted to enter the password for the first time.

Resource Aggregator for ODIM uses the odim-vault tool to encrypt and decrypt passwords.

On the deployment node, navigate to ~/ODIM/odim-controller/scripts.
```
cd ~/ODIM/odim-controller/scripts
```

Build the odim-vault tool.

go build -ldflags "-s -w" -o odim-vault odim-vault.go

Enter a random string in a file called odimVaultKeyFile and save it.
```
vi odimVaultKeyFile
```
The entered string acts as the odim-vault crypto key. It is required for encrypting and decrypting the local user password of the Kubernetes cluster nodes.
To encode the entered odim-vault crypto key, run the following command:
```
./odim-vault -encode ~/ODIM/odim-controller/\
scripts/odimVaultKeyFile
```
Result: odimVaultKeyFile contains the encoded odim-vault master key.

Change the file permissions of odimVaultKeyFile.

chmod 0400 /home/${USER}/ODIM/odim-controller/\
scripts/odimVaultKeyFile

Enter the password of the default non-root user (that was set across all cluster nodes initially) in plain text in a file called nodePasswordFile. Save the file.
```
vi nodePasswordFile
```

To encrypt the entered password, run the following command:

./odim-vault -key ~/ODIM/odim-controller/\
scripts/odimVaultKeyFile -encrypt /home/${USER}/ODIM/odim-controller/\
scripts/nodePasswordFile

Result: nodePasswordFile contains the encrypted node password.

Change the file permissions of nodePasswordFile.

chmod 0400 /home/${USER}/ODIM/odim-controller/\
scripts/nodePasswordFile

Log path for odim-controller

You can provide a desired file path for the odim-controller logs by setting ODIM_CONTROLLER_LOG_PATH environment variable. Upon the execution of odim-controller, the log file will then be stored as {ODIM_CONTROLLER_LOG_PATH}/odim-controller.log.

If the environment variable is not set, the log file will be stored in the current directory where odim-controller was executed.

Upon each execution of odim-controller, the following information is logged:

Start time and end time of the execution
User and the groups, user belongs to
Options passed to odim-controller
Complete output of the operation

Deploying Resource Aggregator for ODIM and the Plugins

Topics covered in this section include:

Deploying the resource aggregator services
Deploying the Unmanaged Rack Plugin (URP)
Deploying the Dell plugin
Deploying the Cisco ACI plugin
Adding a plugin into the Resource Aggregator for ODIM framework

Deploying the resource aggregator services

Prerequisites

Ensure all the Predeployment procedures are complete.

Perform the following steps to update the odim-controller configuration file:

Navigate to ~/ODIM/odim-controller/scripts on the deployment node.
```
cd ~/ODIM/odim-controller/scripts
```
Copy content from the kube_deploy_nodes.yaml.tmpl file to the kube_deploy_nodes.yaml file by running the following command:
```
cp kube_deploy_nodes.yaml.tmpl kube_deploy_nodes.yaml
```

Edit the kube_deploy_nodes.yaml file.

vi kube_deploy_nodes.yaml

The kube_deploy_nodes.yaml file is the configuration file used by odim-controller to set up a Kubernetes cluster and to deploy the Resource Aggregator for ODIM services.

NOTE: Do not change the format of the content in this file. Doing so might interrupt the Resource Aggregator for ODIM deployment process.

When you open the kube_deploy_nodes.yaml file for the first time, it looks like the following (for a three node cluster):

Set up a Kubernetes cluster by performing the following procedure:
1. Navigate to odim-controller/scripts on the deployment node:
```
cd ~/ODIM/odim-controller/scripts
```
2. Run the following command on the deployment node:
```
python3 odim-controller.py --deploy \
kubernetes --config /home/${USER}/ODIM/odim-controller/\
scripts/kube_deploy_nodes.yaml
```
3. Enable the non-root user to access the Kubernetes command-line tool (kubectl) on the cluster nodes. Run the following commands on each cluster node:
```
mkdir -p $HOME/.kube
```
```
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
```
```
sudo chown $(id -u):$(id -g) $HOME/.kube/config
```
4. Verify that the Kubernetes pods are up and running in the cluster nodes. Run the following command on each cluster node:
```
kubectl get pods -n kube-system -o wide
```
  Example output:
Deploy the resource aggregator services:
1. Log in to the deployment node and run the following command:
```
python3 odim-controller.py --deploy \
odimra --config /home/${USER}/ODIM/odim-controller/\
scripts/kube_deploy_nodes.yaml
```
  All the resource aggregator services and the third-party services are successfully deployed.
2. Log in to each cluster node, run the following command on each cluster node to verify all deployed services are running successfully.
```
kubectl get pods -n odim -o wide
```
  Example output:
  If the services are not successfully deployed, reset the deployment and try deploying again. To reset, run the following command:
```
python3 odim-controller.py --reset odimra --config \
/home/${USER}/ODIM/odim-controller/scripts/kube_deploy_nodes.yaml \
--ignore-errors
```
  For a three-node cluster deployment, resetting deployment removes the virtual IP configured through Keepalived. After resetting the deployment, restart the Keepalived service. Also, ensure the parameters in the kube_deploy_nodes.yaml are not NULL. Update such parameters to "" or as per your requirement. For example: After resetting the deployment, update the odimCertsPath parameter to "" or to your actual certificate path in the kube_deploy_nodes.yaml file.
NOTE: Save the RootServiceUUID in the kube_deploy_nodes.yaml file in the path ~/ODIM/odim-controller/scripts/kube_deploy_nodes.yaml. If the services are not successfully deployed and you want to reset the deployment, you can use the saved RootServiceUUID.
Perform HTTP GET on /redfish/v1 using the following curl command on your deployment node.

IMPORTANT: Before running curl commands, unset http and https proxies, check if you have set proxy configuration. If yes, set "no_proxy" using the following commands:

unset https_proxy

unset http_proxy

export no_proxy="127.0.0.1,localhost,\
localhost.localdomain,10.96.0.0/12,\
<Comma-seperated_list_of_IP_addresses_of_the_deployment_node_and_the_cluster_nodes>"

Verify that all the resource aggregator services are listed in the JSON response body by running the following curl command:

curl -s --cacert \ 
{path_of_rootCA.crt} \ 
'https://{odim_host}:{port}/redfish/v1' -k

Replace {path_of_rootCA.crt} with the path specified for the odimCertsPath parameter in the kube_deploy_nodes.yaml file - <odimcertsPath>/rootCA.crt. The rootCA.crt file is required for secure SSL communication.
{odim_host} is the virtual IP address of the Kubernetes cluster.

NOTE: For a single node cluster configuration, {odim_host} is the ip address of master node. For a three node cluster configuration, to use FQDN as `{odim_host}`, ensure that FQDN is configured to the virtual IP address in the `/etc/hosts` file or in the DNS server.

{port} is the API server port configured in Nginx. Default port is 30080. If you have changed the default port, use that as the port.

The following JSON response is returned:

Adding a plugin into the Resource Aggregator for ODIM framework

After a plugin is successfully deployed, you must add the plugin into the Resource Aggregator for ODIM framework to access the plugin service.

Prerequisites

The plugin you want to add is successfully deployed.

To add a plugin, perform HTTP POST on the following URI:

https://{odim_host}:{port}/redfish/v1/AggregationService/AggregationSources

{odim_host} is the virtual IP address of the Kubernetes cluster. For one-node odim deployment, odim_host is the IP address of the master node.
{port} is the API server port configured in Nginx. Default port is 30080. If you have changed the default port, use that as the port.

The following ports (except container ports) must be free:

Port name	Ports
Container ports (access restricted only to the Kubernetes cluster network)	45000 — API service port 45101- 45201 — Resource Aggregator for ODIM service ports 9082, 9092 — Kafka ports 6379 — Redis port 26379 — Redis Sentinel port 2181 — Zookeeper port 2379, 2380 — etcd ports

Postdeployment operations

This section lists all the operations that you can perform after successfully deploying Resource Aggregator for ODIM. You can perform these operations to modify or upgrade the existing Kubernetes deployment.

NOTE: The operations listed in this section are not mandatory.

Scaling up the resources and services of Resource Aggregator for ODIM

Following are the two ways of scaling up the resources and services of Resource Aggregator for ODIM deployed in a Kubernetes cluster:

Horizontal scaling: It involves adding one or more worker nodes to the existing three-node cluster.

NOTE: Scaling of a one-node cluster is not supported—you cannot add nodes to a one-node cluster.
Vertical scaling: It involves creating multiple instances of the resource aggregator and plugin services.

NOTE:Scaling of third-party services is not supported.

To add a node, run the following command on the deployment node:
```
python3 odim-controller.py --addnode kubernetes --config \
/home/${USER}/ODIM/odim-controller/scripts/kube_deploy_nodes.yaml
```
Before adding a node, ensure that time on the node is same as the time on all the other existing nodes. To know how to set time sync, see Setting up time sync across nodes.
Log in to each cluster node and update all the configuration files inside /opt/nginx/servers with the new node details.
To scale up the resource aggregator deployments, run the following command on the deployment node:
```
python3 odim-controller.py --config \
/home/${USER}/ODIM/odim-controller/scripts/kube_deploy_nodes.yaml \
--scale --svc aggregation --replicas <replica_count>
```
Replace <deployment_name> with the name of the deployment which you want to scale up. To know all the supported deployment names, see Resource Aggregator for ODIM deployment names.

Replace <replica_count> with an integer indicating the number of service instances to be added.
To scale up the plugin services, run the following command on the deployment node:
```
python3 odim-controller.py --config \
/home/${USER}/ODIM/odim-controller/scripts/\
kube_deploy_nodes.yaml --scale --plugin <plugin_name> --replicas <replica_count>
```
Replace <plugin_name> with the name of the plugin whose service you want to scale up.

Replace <replica_count> with an integer indicating the number of plugin service instances to be added.

Scaling down the resources and services of Resource Aggregator for ODIM

Scaling down involves removing one or more worker nodes from an existing three-node cluster where the services of Resource Aggregator for ODIM are deployed.

To remove a node, do the following:
1. Open the kube\_deploy\_nodes.yaml file on the deployment node.
2. Remove all the node entries under nodes except for the node that you want to remove.
3. Run the following command:
```
python3 odim-controller.py --rmnode kubernetes --config \
/home/${USER}/ODIM/odim-controller/scripts/kube_deploy_nodes.yaml
```
To scale down the resource aggregator deployments, run the following command on the deployment node:
```
python3 odim-controller.py --config \
/home/${USER}/ODIM/odim-controller/scripts/kube_deploy_nodes.yaml \
--scale --svc aggregation --replicas <replica_count>
```
Replace <deployment_name> with the name of the deployment which you want to scale down. To know all the supported deployment names, see Resource Aggregator for ODIM deployment names.

Replace <replica_count> with an integer indicating the number of service instances to be removed.
To scale down the plugin services, run the following command on the deployment node:
```
python3 odim-controller.py --config \
/home/${USER}/ODIM/odim-controller/scripts/kube_deploy_nodes.yaml \
--scale --plugin <plugin_name> --replicas <replica_count>
```
Replace <plugin_name> with the name of the plugin whose service you want to scale up.

Replace <replica_count> with an integer indicating the number of plugin service instances to be removed.

Rolling back to an earlier deployment revision

Rolling back the deployment of Resource Aggregator for ODIM to a particular revision restores the configuration manifest of that version.

To list the revision history of the deployment of Resource Aggregator for ODIM, run the following command:
```
python3 odim-controller.py --config \
/home/${USER}/ODIM/odim-controller/scripts/kube_deploy_nodes.yaml --list \
history --dep <deployment_name>
```
Replace <deployment_name> with the name of the deployment for which you want to list the revision history. To know all the supported deployment names, see HPE Resource Aggregator for ODIM deployment names.

You will receive a list of revisions along with the revision numbers.

To roll back the deployment of Resource Aggregator for ODIM to a particular revision, run the following command:

python3 odim-controller.py --config \
/home/${USER}/ODIM/odim-controller/scripts/kube_deploy_nodes.yaml --rollback \

Running curl commands on a different server

To run curl commands on a different server, perform the following steps to provide the rootCA.crt file.

Navigate to the path specified for the odimCertsPath parameter in the kube_deploy_nodes.yaml file on the deployment node.
Copy the rootCA.crt file.
Log in to your server and paste the rootCA.crt file in a folder.
Open the /etc/hosts file to edit.
Scroll to the end of the file, add the following line, and then save:
```
<hostvm_ipv4_address> <FQDN>
```

Check if curl is working by using the following command:

curl --cacert rootCA.crt 'https://{odim_host}:{port}/redfish/v1'

NOTE: - To avoid using the `--cacert` flag in every curl command, add `rootCA.crt` in the `ca-certificates.crt` file available in this path: `/etc/ssl/certs/ca-certificates.crt`. You can access the base URL using a REST client. To access it using a REST client, add the rootCA.crt file of HPE Resource Aggregator for ODIM to the browser where the REST client is launched.

Using your own CA certificates and keys

Generate the following certificates and store them in a folder on the deployment node:
- odimra_rsa.private: It must be generated only once before deploying the resource aggregator and plugin services.
- odimra_rsa.public: It must be generated only once before deploying the resource aggregator and plugin services.
  
  NOTE: Ensure not to replace the RSA public and private keys. Replacing them results in loss of data and requires reinstallation. If you are generating your own CA certificates to replace the existing CA certificates, move the existing odimra\_rsa.public and odimra\_rsa.private files to the folder where you are generating all the other certificates.
- rootCA.crt: Root CA certificate.
- odimra_server.crt: Certificate to be used by the API gateway and the resource aggregator and plugin components.
- odimra_server.key: Private key to be used by the API gateway and the resource aggregator and plugin components.
- odimra_kafka_client.crt: Kafka certificate.
- odimra_kafka_client.key: Kafka key.
- kafka.keystore.jks: Keystore of type jks used by Kafka servers for TLS-based communication.
- kafka.truststore.jks: Truststore of type jks. It contains CA certificates, used by Kafka server to validate certificates of the client that is contacting the Kafka server.
- zookeeper.keystore.jks: Keystore of type jks used by Zookeeper for TLS-based communication.
- zookeeper.truststore.jks: Truststore of type jks. It contains CA certificates, used by Zookeeper to validate certificates of the client that is contacting it.
While generating these certificates:
- Ensure that odimra_server.crt has the SAN entry of FQDN specified in the kube_deploy_nodes.yaml file.
- Ensure that odim_server.crt and odim_kafka_client.crt have the following SAN entries for all the plugins you want to deploy.
  
  Examples: grfplugin: grfplugin,grfplugin-events.
- Ensure that kafka.truststore.jks and kafka.truststore.jks have the following SAN entries:
```
DNS.1 = kafka
DNS.2 = kafka1.kafka.${ODIMRA_NAMESPACE}.svc.cluster.local
DNS.3 = kafka2.kafka.${ODIMRA_NAMESPACE}.svc.cluster.local
DNS.4 = kafka3.kafka.${ODIMRA_NAMESPACE}.svc.cluster.local
DNS.5 = kafka-ext
DNS.6 = kafka1-ext
DNS.7 = kafka2-ext
DNS.8 = kafka3-ext
```
- Ensure that zookeeper.truststore.jks and zookeeper.truststore.jks have the following SAN entries:
```
DNS.1 = zookeeper
DNS.2 = zookeeper1.zookeeper.${ODIMRA_NAMESPACE}.svc.cluster.local
DNS.3 = zookeeper2.zookeeper.${ODIMRA_NAMESPACE}.svc.cluster.local
DNS.4 = zookeeper3.zookeeper.${ODIMRA_NAMESPACE}.svc.cluster.local
```
Replace {ODIMRA_NAMESPACE} with the value specified for namespace in the kube_deploy_nodes.yaml file.
Update odimCertsPath with the path of the folder where you have stored the certificates in the kube_deploy_nodes.yaml file.
[Optional] Perform this step only after you have successfully deployed the resource aggregator and plugin services.

If you want to replace the existing CA certificates, run the following command:

python3 odim-controller.py --config \
/home/${USER}/ODIM/odim-controller/scripts/kube_deploy_nodes.yaml --upgrade odimra-secret

Result: The existing certificates are replaced with the new certificates and the resource aggregator pods are restarted.

Deploying the GRF plugin

Prerequisites

Kubernetes cluster is set up and the resource aggregator is successfully deployed.

Create a directory called plugins on the deployment node.
```
mkdir -p ~/plugins
```
In the plugins directory, create a directory called grfplugin.
```
mkdir ~/plugins/grfplugin
```

On the deployment node, copy the GRF configuration file and the hook script to ~/plugins/grfplugin.

cp ~/ODIM/odim-controller/helmcharts/grfplugin/grfplugin-config.yaml ~/plugins/grfplugin

cp ~/ODIM/odim-controller/helmcharts/grfplugin/grfplugin.sh ~/plugins/grfplugin

Open the GRF plugin configuration YAML file.

vi ~/plugins/grfplugin/grfplugin-config.yaml

Sample grfplugin-config.yaml file:

Replacing an unreachable controller node with a new one

Set the following environment variables on the deployment node:

export NEW_CONTROLLER_NODE_IP=<IP_address_of_new_controller_node>

export NEW_CONTROLLER_NODE_HOSTNAME=<Hostname_of_new_controller_node>

export DEPLOYMENT_ID=<Deployment_ID_of_the_cluster_being_updated>

export ODIM_CONTROLLER_SRC_PATH=/home/${USER}/ODIM/odim-controller

export ODIM_CONTROLLER_CONFIG_FILE=/home/${USER}/ODIM/\
odim-controller/scripts/kube_deploy_nodes.yaml

export K8S_INVENTORY_FILE=${ODIM_CONTROLLER_SRC_PATH}/kubespray/inventory/k8s-cluster-${DEPLOYMENT_ID}/hosts.yaml

Replace {ODIM_CONTROLLER_SRC_PATH} with:

/home/$\{USER\}/ODIM/odim-controller.

Replace {DEPLOYMENT_ID} with the deployment Id of the cluster being updated.

Perform the following steps on one of the controller nodes:
1. Mark the failed controller node as unschedulable:
```
kubectl cordon <Failed_Controller_HostName>
```
2. Delete the failed controller node from the cluster:
```
kubectl delete node <Failed_Controller_HostName>
```
3. Get the container name of etcd:
```
sudo docker ps | grep etcd | awk '{print $10}'
```
4. List the etcd members to obtain the member Id of the failed controller node.
```
sudo docker exec -it <etcd_container_name> etcdctl member list
```
5. Remove the failed controller node from the etcd cluster:
```
sudo docker exec -it <etcd_container_name> etcdctl member remove <failed_node_etcd_member_id>
```

Perform the following steps on the deployment node:

Enable passwordless login for the new controller node.

/usr/bin/ssh-copy-id -o StrictHostKeyChecking=no -i ~/.ssh/id_rsa.pub ${USER}@${New_Controller_Node_IP}

Verify that time on the new controller node is in sync with the deployment node and other cluster nodes.
Edit ${K8S_INVENTORY_FILE} to:
- Remove the failed controller node details.
- Add the new controller node details under the following sections:
  - etcd
  - kube_control_plane
  - kube_node
  - hosts
```
vi ${K8S_INVENTORY_FILE}
```
Edit \{ODIM\_CONTROLLER\_SRC\_PATH\}/kubespray/inventory/k8s-cluster-$\{DEPLOYMENT\_ID\}/group\_vars/all/all.yml to:
- Update the no_proxy parameter with the new controller node IP.
- Remove the failed controller node IP from the no_proxy list.

Run the following commands:

cp ${ODIM_CONTROLLER_CONFIG_FILE} ${ODIM_CONTROLLER_SRC_PATH}/\
odimra/roles/k8-copy-image/files/helm_config_values.yaml

cd ${ODIM_CONTROLLER_SRC_PATH}/odimra

ansible-playbook -K -i ${K8S_INVENTORY_FILE} --become \
--become-user=root --extra-vars "host=${NEW_CONTROLLER_NODE_HOSTNAME}" \
k8_copy_image.yaml

When prompted for password, enter the sudo password of the node.

cd ${ODIM_CONTROLLER_SRC_PATH}/kubespray

ansible-playbook -K -i ${K8S_INVENTORY_FILE} \
--become --become-user=root --limit=etcd,kube_control_plane \
-e ignore_assert_errors=yes cluster.yml

Run the following command on any of the cluster nodes:

kubectl get nodes -o wide

If any of the nodes are listed as "Ready,Unschedulable", run the following commands on any of the existing controller nodes:

kubectl uncordon <unschedulable_controller_node_name>

cd ${ODIM_CONTROLLER_SRC_PATH}/odimra

cp ${ODIM_CONTROLLER_CONFIG_FILE} ${ODIM_CONTROLLER_SRC_PATH}\
/odimra/roles/pre-install/files/helmcharts/helm_config_values.yaml

cp ${ODIM_CONTROLLER_CONFIG_FILE} ${ODIM_CONTROLLER_SRC_PATH}\
/odimra/roles/odimra-copy-image/files/odimra_config_values.yaml

ansible-playbook -K -i ${K8S_INVENTORY_FILE} \
--become --become-user=root --extra-vars \
"host=${New_Controller_Node_HostName}" pre_install.yaml

rm -f  ${ODIM_CONTROLLER_SRC_PATH}/odimra/roles/\
k8-copy-image/files/helm_config_values.yaml \
${ODIM_CONTROLLER_SRC_PATH}/odimra/roles/pre-install/\
files/helmcharts/helm_config_values.yaml ${ODIM_CONTROLLER_SRC_PATH}/\
odimra/roles/odimra-copy-image/files/odimra_config_values.yaml

[Optional] If the failed node becomes accessible later, run the following commands on the failed node to uninstall Kubernetes:

kubectl drain <node name> --delete-local-data \
--force --ignore-daemonsets

sudo kubeadm reset

sudo apt-get -y autoremove --purge \
kubeadm kubectl kubelet kubernetes-cni

sudo rm -rf /etc/cni /etc/kubernetes /var/lib/dockershim \
/var/lib/etcd /var/lib/kubelet /var/run/kubernetes ~/.kube/*

sudo systemctl restart docker

Replacing an unreachable controller node with an existing worker node

Set the following environment variables on the deployment node:

export EXISTING_WORKER_NODE_IP=<IP_address_of_existing_worker_node>

export EXISTING_WORKER_NODE_HOSTNAME=<Hostname_of_existing_worker_node>

export DEPLOYMENT_ID=<Deployment_ID_of_the_cluster_being_updated>

export ODIM_CONTROLLER_SRC_PATH=/home/${USER}/ODIM/odim-controller

export ODIM_CONTROLLER_CONFIG_FILE=/home/${USER}/ODIM/odim-controller/\
scripts/kube_deploy_nodes.yaml

export K8S_INVENTORY_FILE=${ODIM_CONTROLLER_SRC_PATH}/kubespray/inventory/k8s-cluster-${DEPLOYMENT_ID}/hosts.yaml

Replace \{ODIM\_CONTROLLER\_SRC\_PATH\} with:

/home/$\{USER\}/ODIM/odim-controller.

Replace {DEPLOYMENT_ID} with the deployment Id of the cluster being updated.

Perform the following steps on one of the controller nodes:
1. Mark the failed controller node as unschedulable:
```
kubectl cordon <Failed_Controller_HostName>
```
2. Delete the failed controller node from the cluster:
```
kubectl delete node <Failed_Controller_HostName>
```
3. Get the container name of etcd:
```
sudo docker ps | grep etcd | awk '{print $10}'
```
4. List the etcd members to obtain the member Id of the failed controller node.
```
sudo docker exec -it <etcd_container_name> etcdctl member list
```
5. Remove the failed controller node from the etcd cluster:
```
sudo docker exec -it <etcd_container_name> etcdctl member remove <failed_node_etcd_member_id>
```

Perform the following steps on the deployment node:

Remove the existing worker node. To know how to remove a node, see step 1 in Scaling down the resources and services of HPE Resource Aggregator for ODIM.
Edit $\{K8S\_INVENTORY\_FILE\} to add the removed worker node as a new controller node with required details under the following sections.
- etcd
- kube_control_plane
- kube_node
- hosts
```
vi ${K8S_INVENTORY_FILE}
```
Edit \{ODIM\_CONTROLLER\_SRC\_PATH\}/kubespray/inventory/k8s-cluster-$\{DEPLOYMENT\_ID\}/group\_vars/all/all.yml to:
- Update the no_proxy parameter with the removed worker node IP.
- Remove the failed controller node IP from the no_proxy list.

Run the following commands:

cp ${ODIM_CONTROLLER_CONFIG_FILE} ${ODIM_CONTROLLER_SRC_PATH}/\

Removing an existing plugin

To remove an existing plugin from the Resource Aggregator for ODIM framework, run the following command:

python3 odim-controller.py --config \
/home/${USER}/ODIM/odim-controller/scripts/kube_deploy_nodes.yaml \
--remove plugin --plugin <plugin_name>

Uninstalling the resource aggregator services

To remove all the resource aggregator services, run the following command:

python3 odim-controller.py --reset odimra --config \
/home/${USER}/ODIM/odim-controller/scripts/kube_deploy_nodes.yaml

To uninstall all the resource aggregator services by ignoring any errors you may encounter, use the following command:

python3 odim-controller.py --reset odimra --config \
/home/${USER}/ODIM/odim-controller/scripts/kube_deploy_nodes.yaml \
--ignore-errors

CI process

GitHub action workflows, also known as checks, are added to the ODIM repository. They are triggered whenever a Pull Request (PR) is raised against the master (development) branch. The result from the workflow execution is then updated to the PR.

NOTE: You can review and merge PRs only if the checks are passed.

Following checks are added as part of the CI process:

Sl No.	Workflow Name	Description
1	`build_unittest.yml`	Builds and runs Unit Tests with code coverage enabled.
2	`build_deploy_test.yml`	Builds, deploys, runs sanity tests, and uploads build artifacts (like odimra logs).

These checks run in parallel and take approximately 9 minutes to complete.
