This is a walkthrough of setting the Couchbase Operator up on Oracle Cloud Infrastructure Container Engine for Kubernetes (OKE). It is developed jointly by Oracle and Couchbase.
First you're going to need to setup an Oracle Cloud account, your environmental variables, an OKE cluster and your kubectl. It sounds like a lot, but there's a nice walkthrough here that should help.
Great, you made it!
Once you have an OKE cluster deployed and a running kubectl, you're ready to deploy the Operator. The documentation on that is here.
First, you need to download stuff. This includes a customer kubectl as Couchbase has forked it and created their own. There are per platform binaries for those. This downloads the Mac one:
curl -O https://s3.amazonaws.com/packages.couchbase.com/kubernetes/1.0.0/couchbase-autonomous-operator-kubernetes_1.0.0-macos_x86_64.zip
unzip couchbase-autonomous-operator-kubernetes_1.0.0-macos_x86_64.zip
cd couchbase-autonomous-operator-kubernetes_1.0.0-macos_x86_64
ls
That gives this:
To create the deployment and check it deployed, run this:
kubectl create -f cluster-role.yaml
kubectl create serviceaccount couchbase-operator --namespace default
kubectl create clusterrolebinding couchbase-operator --clusterrole couchbase-operator --serviceaccount default:couchbase-operator
kubectl create -f operator.yaml
When you've done all that, you can check the Operator deployed with:
kubectl get deployments
You should see something like this:
We're there! Time to get a live cluster. Run this:
kubectl create -f secret.yaml
kubectl create -f couchbase-cluster.yaml
That should give this:
You can view the Couchbase and operator pods by running:
kubectl get pods
This gives:
You've now got a cluster. But to use it you probably want to set up port forwarding. To do that run:
kubectl port-forward cb-example-0000 8091:8091
Leave that command running:
Now open up a browser to http://localhost:8091
The username is Administrator and password is password. And now you're in!
If you want to delete the Operator, you can run this:
kubectl delete deployment couchbase-operator
kubectl delete crd couchbaseclusters.couchbase.com
That gives this:
