Operator SDK: Helm Chart

1. Create Operator

You need first to create Helm Chart as described here.

Then, you can generate the operator with the following commands.

operator-sdk init --plugins=helm
operator-sdk create api --group=hazelcast --version=v1 --helm-chart=./chart

2. Dockerize operator application and push it into Docker Hub

docker build -t leszko/hazelcast-operator:helm . && docker push leszko/hazelcast-operator:helm

3. Create Hazelcast CRD (Custom Role Definition)

make install

4. Deploy an operator

make deploy IMG=leszko/hazelcast-operator:helm

Check that the operator is running with the following command.

kubectl logs deployment.apps/helm-controller-manager -n helm-system -c manager

5. Create Hazelcast Resource

kubectl apply -f config/samples/hazelcast_v1_hazelcast.yaml

Note: If you want Hazelcast members themselves to form a cluster, you need to configure RBAC for Hazelcast: kubectl apply -f https://raw.githubusercontent.com/hazelcast/hazelcast-kubernetes/master/rbac.yaml.

6. Clean up

kubectl delete -f config/samples/hazelcast_v1_hazelcast.yaml
make undeploy
