• https://kubernetes.io/docs/concepts/extend-kubernetes/#extension-patterns
• https://kubernetes.io/docs/concepts/extend-kubernetes/operator/

This operator was built using Operator SDK. please see:

Running on a cluster and testing

First, deploy the Operator and the Custom Resource Definition (CRD) - make deploy.

If you wish to debug see the "debugging" section below, and either scale down the controller-manager Deployment to 0 first, or use make install instead.

Next, deploy the user input Custom Resource example Config Map and UStore yaml:

oc apply -f config/samples/sample-config-ucset.yaml
oc apply -f config/samples/unum_v1alpha1_ustore_ucset.yaml 

Note: there are more yamls under config/samples

Cleanup

oc delete -f config/samples/unum_v1alpha1_ustore_ucset.yaml 
make undeploy

Building locally if needed

IMAGE_BUILDER=docker #its podman by default
IMG=<your local operator image to build>
make docker-build
make docker-push

A push to main branch, triggers image build GH Action. image name: quay.io/opdev/ustore-operator

Operator Lifecycle Manager (OLM) Bundle and OpenShift Marketplace integration

To generate bundle manifests use make bundle. Observe config/manifests/bases/ustore-operator.clusterserviceversion.yaml and the bundle folder.

To build the bundle image which can be tested, certified and pushed to marketplace use

IMAGE_BUILDER=docker #its podman by default
IMAGE_TAG_BASE=<name of image. will be appended with -bundle>
make bundle-build
make bundle-push

This image can then be added to a test catalog for local testing only

make catalog-build
make catalog-push
