Task List

Phase I

• Confirm with Community Representative that the hub is no longer in use and it's safe to decommission
• Confirm if there is any data to migrate from the hub before decommissioning
  • If yes, confirm where the data should be migrated to
    • Confirm a 2i2c Engineer has access to the destination in order to complete the data migration
  • If no, confirm it is ok to delete all the data stored in the user home directories

Phase II - Hub Removal

(These steps are decribed in more detail in the docs at https://infrastructure.2i2c.org/en/latest/howto/hubs/delete-hub.html.)

• Manage existing data (migrate data from the hub or delete it)
• Remove the appropriate config/clusters/<cluster_name>/<hub_name>.values.yaml files. A complete list of relevant files can be found under the appropriate entry in the associated cluster.yaml file.
• Remove the associated hub entry from the config/clusters/<cluster_name>/cluster.yaml file.
• Remove the hub deployment
  • helm --namespace HUB_NAME delete HUB_NAME
  • kubectl delete namespace HUB_NAME
• Delete the hub's authentication application on auth0, GitHub or CILogon

Phase III - Cluster Removal

This phase is only necessary for single hub clusters.

• Run terraform plan -destroy and terraform apply from the appropriate workspace, to destroy the cluster
• Remove the associated config/clusters/<cluster_name> directory and all its contents
• Remove the cluster from CI:
  • deploy-hubs.yaml
  • validate-clusters.yaml
• Remove the cluster from the list of grafana datasources at https://grafana.pilot.2i2c.cloud/datasources

Confirmed! You can take it down whenever you are ready. Thanks!

We've already migrated off data that we'd like to retain, so it is OK to delete everything stored there.

I believe this event is over and the associated hub has been decommissioned. I am closing this issue.

[damianavila]

I reopened it because we need to merge #1721 and confirm some of the items listed above before closing it 😉.

[GeorgianaElena]

I've merged the PR and I confirm I followed all the manual decommissioning steps in the docs
