5.6.2.5.2. Running as a deployment on the cluster

Procedure

1. Run the following make commands to build and push the Operator image. Modify the IMG argument in the following steps to reference a repository that you have access to. You can obtain an account for storing containers at repository sites such as Quay.io.

   1. Build the image:

      $ make docker-build IMG=<registry>/<user>/<image_name>:<tag>

      注意

      The Dockerfile generated by the SDK for the Operator explicitly references GOARCH=amd64 for go build. This can be amended to GOARCH=$TARGETARCH for non-AMD64 architectures. Docker will automatically set the environment variable to the value specified by –platform. With Buildah, the –build-arg will need to be used for the purpose. For more information, see Multiple Architectures.

   2. Push the image to a repository:

      $ make docker-push IMG=<registry>/<user>/<image_name>:<tag>

      注意

      The name and tag of the image, for example IMG=<registry>/<user>/<image_name>:<tag>, in both the commands can also be set in your Makefile. Modify the IMG ?= controller:latest value to set your default image name.

2. Run the following command to install the CRD to the default namespace:

   $ oc apply -f target/kubernetes/memcacheds.cache.example.com-v1.yml

   Example output

   customresourcedefinition.apiextensions.k8s.io/memcacheds.cache.example.com created

3. Create a file called rbac.yaml as shown in the following example:

   apiVersion: rbac.authorization.k8s.io/v1
   kind: ClusterRoleBinding
   metadata:
     name: memcached-operator-admin
   subjects:
   - kind: ServiceAccount
     name: memcached-quarkus-operator-operator
     namespace: <operator_namespace>
   roleRef:
     kind: ClusterRole
     name: cluster-admin
     apiGroup: ""

   重要

   The rbac.yaml file will be applied at a later step.

4. Run the following command to deploy the Operator:

   $ make deploy IMG=<registry>/<user>/<image_name>:<tag>

5. Run the following command to grant cluster-admin privileges to the memcached-quarkus-operator-operator by applying the rbac.yaml file created in a previous step:

   $ oc apply -f rbac.yaml

6. Run the following command to verify that the Operator is running:

   $ oc get all -n default

   Example output

   NAME                                                      READY   UP-TO-DATE   AVAILABLE   AGE
   pod/memcached-quarkus-operator-operator-7db86ccf58-k4mlm   0/1       Running   0           18s

7. Run the following command to apply the memcached-sample.yaml and create the memcached-sample pod:

   $ oc apply -f memcached-sample.yaml

   Example output

   memcached.cache.example.com/memcached-sample created
