About

Kustomize Transformer Configurations for OpenShift types namely, BuildConfigs, Imagestreams and DeploymentConfigs.

How to use it with your openshift objects

1. Download and copy over the kustomizeconfig directory into $TEMPLATE_HOME/kustomizeconfig.
2. Update your kustomization.yaml to include all the configurations in kustomization.yaml

Note: kustomize doesn't allow specification of remote urls for configurations in kustomization.yaml

Usage

Assuming the kustomize workspace looks like:

├── kustomization.yaml
├── overlays
│   └── dev
│       ├── kustomization.yaml
│       └── service_port.yaml
└── resources
    ├── _helpers.tpl
    ├── buildconfig.yaml
    ├── deployment.yaml
    ├── imagestream.yaml
    ├── route.yaml
    └── service.yaml

To add a transformer config to custom OpenShift types like BuildConfig, we need to convey to Kustomize where in the spec lies the image.

Similarly, we need to convey the path to the image specification in a DeploymentConfig and in an Imagestream.

The configuratiom for ImageStreams, BuildConfigs and DeploymentConfigs are maintained in openshift-kustomizeconfigs/kustomizeconfig. They can be used of the box by copying over the directory into your Kustomize workspace as shown below.

├── kustomization.yaml
├── kustomizeconfig
│   ├── buildconfig.yaml
│   ├── deploymentconfig.yaml
│   └── imagestream.yaml
├── overlays
│   └── dev
│       ├── buildconfig.yaml
│       ├── kustomization.yaml
│       └── service_port.yaml
└── resources
    ├── buildconfig.yaml
    ├── deployment.yaml
    ├── imagestream.yaml
    ├── route.yaml
    └── service.yaml

To enable it, add the following to your base kustomization.yaml

configurations: 
  - kustomizeconfig/imagestream.yaml
  - kustomizeconfig/buildconfig.yaml
  - kustomizeconfig/deploymentconfig.yaml
