Remove with Docker

1. Stop the container.

   docker stop container-name

2. Determine if the container is still listed.

   docker ps -a \
   --filter name=container-name --format "table {{.ID}}\t{{.Names}}\t{{.Image}}" | \
   grep container-name
   

   Here is an example of the output:

   0180fa635ac2 container-name
   container-name:3.4.9-201
   80827.1535411348184
   

   If the output is empty, skip to step 4.

3. Remove the container.

   docker rm container-name

4. (Optional) If the image is no longer needed, then remove it.

   docker rmi image-name

Remove with Kubernetes

1. Verify that the images are still running.

   kubectl -n sas-viya get pods | grep sas

   The output is a list of pods and their status.

2. Remove the service and pod.

   Delete the viya-programming/viya-single-container objects

   kubectl -n sas-viya delete -f run/programming.yml
   

   Delete the multiple deployment objects

   kubectl -n sas-viya delete -f builds/multiple/manifests/kubernetes/deployments/
   kubectl -n sas-viya delete -f builds/multiple/manifests/kubernetes/services/
   kubectl -n sas-viya delete -f builds/multiple/manifests/kubernetes/secrets/
   kubectl -n sas-viya delete -f builds/multiple/manifests/kubernetes/configmaps/
   kubectl -n sas-viya delete -f builds/multiple/manifests/kubernetes/ingress/
   

   Delete the full deployment objects

   kubectl -n sas-viya delete -f builds/full/manifests/kubernetes/deployments/
   kubectl -n sas-viya delete -f builds/full/manifests/kubernetes/services/
   kubectl -n sas-viya delete -f builds/full/manifests/kubernetes/secrets/
   kubectl -n sas-viya delete -f builds/full/manifests/kubernetes/configmaps/
   kubectl -n sas-viya delete -f builds/full/manifests/kubernetes/ingress/
   

   As the service and pod are removed, messages that indicate success are displayed. Here is an example:

   service "container-name" deleted
   statefulset "container-name" deleted
   

3. (Optional) Verify that the service and pod are removed.

   kubectl -n sas-viya get pods | grep sas

   kubectl -n sas-viya get svc | grep sas

   No results indicate a successful removal of the service and pod.

4. (Optional) If you have the permissions to do so, remove the Kubernetes namespace.

   kubectl delete ns sas-viya
   

(Optional) Clean Up the Docker Registry

If you do not plan to use the images, follow the processes implemented by your company or organization to clean up the Docker registry.

(Optional) Clean Up Docker Images on the Build Machine

• To remove all unused data, see docker system prune.
• To remove images, see docker image rm.
