Description

This project automates the deployment of a MinIO server. It uses Terraform to provision the necessary infrastructure on an OpenStack cloud, including a virtual machine, storage volumes, and networking. Ansible is then used to configure the server, install MinIO, and set up Caddy as a reverse proxy for HTTPS access.

Terraform Variables

The following variables can be set in a terraform.tfvars file to customize the deployment:

Variable	Description	Type	Default
ssh_key_public	The public SSH key to be installed on the server.	string	n/a
floating_ip_pool	The name of the floating IP pool to use.	string	"Ext_Floating_IP"
server_name	The name of the server to be created.	string	"minio"
cidr	The CIDR for the private network.	string	"192.168.90.0/24"
server_flavor	The flavor of the server to be created.	string	"ilifu-B"
domain_name	The domain name for the MinIO server.	string	n/a
server_image	The image to use for the server.	string	"20250728-noble"
minio_volume_size_gib	The size of each MinIO volume in GiB.	number	64
minio_volume_count	The number of MinIO volumes to create.	number	4
minio_volume_name_prefix	The prefix for the MinIO volume names.	string	"minio-data"
locale	The locale to set on the server.	string	"en_ZA.UTF-8"
timezone	The timezone to set on the server.	string	"Africa/Johannesburg"

Running Terraform

1. Navigate to the Terraform directory:

   cd terraform

2. Create a terraform.tfvars file:

   Create a terraform.tfvars file in the terraform directory to set the required variables. At a minimum, you should set ssh_key_public and domain_name.

3. Initialize Terraform:

   terraform init

4. Plan the deployment:

   terraform plan

5. Apply the configuration:

   terraform apply

   Terraform will provision the resources and create an inventory.yaml file in the terraform directory.

Running Ansible

1. Navigate to the root of the project directory.

2. Run the Ansible playbook:

   ansible-playbook -i terraform/inventory.yaml ansible/site.yaml

   Ansible will use the generated inventory to configure the server. The playbook applies the following roles:

   • base: Basic server configuration.
   • xfs_mounts: Formats and mounts the MinIO volumes.
   • caddy: Installs and configures the Caddy reverse proxy.
   • minio: Installs and configures the MinIO server.

Accessing the MinIO Console

To access the MinIO console, you can use SSH port forwarding. The MinIO console runs on port 9001 on the server, and the API is on port 9000.

1. Set up the SSH tunnel:

   ssh -L 9001:localhost:9001 <user>@<floating_ip>

2. Access the console:

   Open your web browser and navigate to http://localhost:9001. You will be prompted for the username and password. The admin username is minioadmin and the password is automatically generated by Terraform and can be found in the terraform/inventory.yaml file after deployment.

Using the MinIO and AWS Clients

The mc and aws command-line clients can be run from any machine that has network access to the MinIO server's API endpoint (i.e., the public floating IP address). This is typically your local machine. You will need to have the respective clients installed.

For authenticating with the MinIO API, you will need an access key and a secret key. For a MinIO user, the access key is their username, and the secret key is their password.

For the initial admin user, the access key is minioadmin and the secret key is the password generated by Terraform, which can be found in the terraform/inventory.yaml file.

MinIO Client (mc)

The MinIO client (mc) is a command-line tool to work with MinIO servers.

1. Configure the mc client:

   mc alias set myminio https://<domain_name> <access_key> <secret_key>

   Replace <domain_name> with the domain name you configured, and <access_key> and <secret_key> with the appropriate credentials (e.g., the minioadmin access key and secret key).

2. Manage users and policies:

   • Add a new user:

     mc admin user add myminio newuser newpassword

   • Attach a policy to a user:

     mc admin policy attach myminio readwrite --user newuser

AWS CLI Client

The AWS CLI can be used to interact with the MinIO server by specifying the endpoint URL.

1. Configure the AWS CLI:

   You can configure the AWS CLI by setting environment variables:

   export AWS_ACCESS_KEY_ID=<access_key>
   export AWS_SECRET_ACCESS_KEY=<secret_key>

2. Use the AWS CLI:

   When using the AWS CLI, you need to specify the endpoint URL of your MinIO server.

   • List buckets:

     aws --endpoint-url https://<domain_name> s3 ls

   • List objects in a bucket:

     aws --endpoint-url https://<domain_name> s3 ls s3://<bucket-name>
