Deploy operator onto the cluster

In the previous step, we created an operator. Now, we deploy it to the cluster. This involves deploying the namespace and the operator files to the cluster. Create the namespace where you want to deploy the operator with the namespace.yaml file we created in step 2 using this command:

$ kubectl apply -f config/deploy/namespace.yaml

When the command runs successfully, it returns namespace/craft created. You can check the namespace created by running this command:

kubectl get namespace

This should display all the existing namespaces, out of which craft is one. Install the operator onto the cluster with this command:

kubectl apply -f config/deploy/operator.yaml

This will create the required pod in the cluster. We can verify the creation by running:

kubectl get pods

This returns the wordpress pod along with the other pods running on your machine:

NAME                                           READY   STATUS         RESTARTS   AGE
wordpress-controller-manager-8844cf545-gn5rt   1/2     Running           0       11s

Great, your pod is running! You are ready to deploy the resource.

NOTE

If your pod’s status is ContainerCreating, run the command again in a few seconds and the status should change to running.

Deploy the resource onto the cluster using the wordpress-dev-withoutvault YAML file created by CRAFT.

kubectl -n craft apply -f config/deploy/wordpress-dev-withoutvault.yaml

This deploys the wordpress resource onto the cluster. To verify, run:

kubectl -n craft port-forward  svc/wordpress-dev 9090:80

Open http://localhost:9090 on the browser and you’ll see the Wordpress application. You can check the logs to see that reconciliation is running as configured. To see that, we can use stern.

stern -n craft .
