Part 5: Deprovision

What Will You Do

In part 5, you will:

  • Deprovision the EKS cluster and all associated infrastructure in AWS

Watch a video of this exercise.

Assumptions

This part assumes that you have completed Part 1 of this series and have a successfully provisioned and healthy EKS cluster.

Deprovision Cluster

Select a method to provision and manage your EKS cluster from the tabs below.

  • Go to Infrastructure -> Clusters.
  • Click on the settings icon of the cluster and select "Delete"
  • When prompted, select "yes" to confirm the deletion of the cluster

Cluster Delete Prompt

  • The cluster provision status will show " INFRA DELETION IN PROGRESS". Note, it can take approximately 20 minutes for the deletion to finish
  • Once the deletion is complete, the cluster will be removed from the web console

Let us first list the EKS cluster using the RCTL CLI

./rctl get cluster

You should expect to see output like the following

+------------------+---------+-----------+----------------------------+
| NAME             | TYPE    | OWNERSHIP | PROVISION STATUS           |
+------------------+---------+-----------+----------------------------+
| demo-eks-testing | aws-eks | self      | CLUSTER_PROVISION_COMPLETE |
+------------------+---------+-----------+----------------------------+

Now, execute the following command to delete your EKS cluster. 

./rctl delete demo-eks-testing

Note

The actual deletion process can take ~10 minutes to ensure that all associated infrastructure resources in AWS is deleted as well.

Step 1: Deprovision Cluster

In this step, we will deprovision the EKS cluster with a Terraform command. The controller will cleanup all cluster components in your Azure account.

  • Execute the following command to begin deprovisioning the cluster. 

    terraform destroy

  • Enter yes when prompted.

The cluster provision status will show " INFRA DELETION IN PROGRESS". Note, it can take approximately 10 minutes for the deletion to finish.

  • Once the deletion is complete, the cluster will be removed from the web console

Recap

Congratulations! At this point, you have successfully deprovisioned the EKS cluster and all associated infrastructure components in your AWS account.
