KOPF (Kubernetes Operator Pythonic Framework)

1. Create operator

The whole logic of the operator is included in the file operator.py.

2. Dockerize operator application and push it into Docker Hub

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

3. Create Hazelcast CRD (Custom Role Definition) and RBAC (Cluster Role and Cluster Role Binding)

kubectl apply -f hazelcast.crd.yaml
kubectl apply -f role.yaml
kubectl apply -f role_binding.yaml

4. Deploy an operator

kubectl apply -f operator.yaml

5. Create Hazelcast Resource

kubectl apply -f 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 hazelcast.yaml
kubectl delete -f operator.yaml
kubectl delete -f role_binding.yaml
kubectl delete -f role.yaml
kubectl delete -f hazelcast.crd.yaml
