Overview

The purpose of this project is to provide a reference kubernetes operator generated by operator-sdk. The latest kubernetes operator is generated by operator-sdk@1.0.1

Development

• Instantiate project with operator-sdk:

# init project: all API groups will be <group>.ajdev.com
operator-sdk init --domain=ajdev.com --repo=github.com/ajgrande924/sandbox-operator

# create memcached api
operator-sdk create api --group cache --version v1 --kind Memcached --resource=true --controller=true

• Update api and controller then update config assets:

# update generated code
make generate

# update manifests
make manifests

• Build operator controller image:

# build / push operator controller image
make docker-build docker-push IMG=docker.io/ajgrande924/sandbox-operator:1.0.1

• Install crd and controller to cluster:

make install
make deploy IMG=docker.io/ajgrande924/sandbox-operator:1.0.1

• Apply custom resource and check:

kubectl apply -f config/samples/cache_v1_memcached.yaml 
kubectl logs deployment.apps/sandbox-operator-controller-manager -n default -c manager

• Cleanup cluster:

kubectl delete -f config/samples/cache_v1_memcached.yaml
kubectl delete deployments,service -l control-plane=controller-manager
kubectl delete role,rolebinding --all
