Run and expose the operator

If on Minikube :

kubectl run terracotta-operator --image-pull-policy='Always' --image=terracotta/terracotta-operator --port=8080
kubectl expose deployment terracotta-operator --name=terracotta-operator-port --type=NodePort
minikube service terracotta-operator-port

If somewhere else :

kubectl run terracotta-operator --image-pull-policy='Always' --image=terracotta/terracotta-operator --port=8080
kubectl expose deployment terracotta-operator --name=operator-port --type=NodePort

Interact with the operator, via Rest

create a new cluster, list it, delete it

To create a new cluster:

curl --header "Content-Type: application/json" \
  --request POST \
  --data '{"offheaps":{"offheap1":"100MB","offheap2":"1GB"},"serversPerStripe":2,"clientReconnectWindow":20}' \
  http://localhost:8080/api/cluster

Check the status of the cluster:

curl http://localhost:8080/api/cluster

Delete the cluster:

curl -X DELETE http://localhost:8080/api/cluster

Interact with the operator, via kubectl and CRDs

kubectl --namespace=thisisatest  apply -f sample-yaml-files/1server-cluster.yaml

and delete :

kubectl --namespace=thisisatest  delete -f sample-yaml-files/1server-cluster.yaml

few notes

super slow to delete a statefulset…
