Site Removal

This section describes how to remove an existing Aether Edge site.

Remove cluster and GCP resources

Clone aether-pod-configs repository.

$ cd $WORKDIR
$ git clone "ssh://[username]@gerrit.opencord.org:29418/aether-pod-configs"

Move the directory to the site you want to delete, ace-test in this example, and remove all files under the directory except for the following three:

backend.tf
cluster_val.tf
provider.tf

$ cd $WORKDIR/aether-pod-configs/production/ace-test
$ rm <files>
$ ls
backend.tf  cluster_val.tfvars  provider.tf
$ cd ../

Next, in the parent directory edit cluster_map.tfvars and vpn_map.tfvars to remove the configurations related to the site.

Once your review request is accepted and merged, Aether CI/CD system starts to destroy K8S cluster in Rancher and VPN, router, and FW resources in GCP.

Attention

Destroying K8S cluster does not clean up the nodes.

Delete deployment jobs

Clone aether-ci-management repository.

$ cd $WORKDIR
$ git clone "ssh://[username]@gerrit.opencord.org:29418/aether-ci-management"

Edit cd-pipeline-terraform.yaml and delete both pre-merge and post-merge jobs.

$ cd $WORKDIR/aether-ci-management
$ vi jjb/repos/cd-pipeline-terraform.yaml

 diff --git a/jjb/repos/cd-pipeline-terraform.yaml b/jjb/repos/cd-pipeline-terraform.yaml

Delete site directory

Finally, delete the remaining site directory from aether-pod-configs.

$ cd $WORKDIR/aether-pod-configs/production
$ rm -rf ace-test

Create a review request.

Note

Terraform state file may still exist in the cloud storage. A new job is required to clean up the state file.
