Operator SDK: Ansible

1. Create Operator

Generate scaffold with the following command.

operator-sdk init --plugins=ansible
operator-sdk create api --group hazelcast --version v1 --kind Hazelcast --generate-role

Then, you can add logic to roles/hazelcast/tasks/main.yaml and role/hazelcast/defaults/main.yaml.

2. Dockerize operator application and push it into Docker Hub

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

3. Create Hazelcast CRD (Custom Role Definition)

make install

4. Deploy an operator

make deploy IMG=leszko/hazelcast-operator:ansible

Check that the operator is running with the following command.

kubectl logs deployment.apps/operator-ansible-controller-manager -n operator-ansible-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
