[colliand]

Summary

Carbon Plan wishes to decommission their hub on Microsoft Azure. They will continue to use their AWS-based hub.

Info

• Community Representative: @andersy005 @norlandrhagen
• Link to New Hub issue: New Hub: CarbonPlan / Azure #800
• Proposed end date: 2022-09-15

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

• Delete the terraform workspace
• 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

Joe noted on Slack that the sponsorship account has been closed out for this hub and that the cluster/hub are down for good: https://2i2c.slack.com/archives/C01DB2JRP8W/p1661288927380899 I asked a clarifying question on whether this means we need to run terraform destroy or if it's just a case of cleaning up the files in our repo.

If it's a case of cleaning up files, I'm more than happy to do that.

@jhamman confirmed in Slack that all resources should be deleted in Azure, so we just need to clean up our repo

@sgibson91 we should probably also delete the terraform workspace we used.

[sgibson91]

@yuvipanda Yup, I had made a mental note but not written it down before a meeting 😄
