[Decommission Hub] tufts.2i2c.cloud

[jmunroe]

Summary

Service agreement not renewed. See https://2i2c.freshdesk.com/a/tickets/1985 for context.

Info

• Community Representative:
• Link to New Hub issue: [Request deployment] New Hub: Tufts University #3470
• Proposed end date: 2024-08-06

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 (Email confirmation received 2024-08-06)

Phase II - Hub Removal

(These steps are described in more detail in the docs at https://infrastructure.2i2c.org/hub-deployment-guide/hubs/delete-hub/)

• Manage existing home directory data (migrate data from the hub or delete it)
• Manage existing cloud bucket data (migrate data, or delete it)
• Delete the hub's authentication application on GitHub or CILogon (note CILogon removal requires the hub config in place)
• 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
  • TIP: Run deployer use-cluster-credentials <cluster_name> before running the above commands

Phase III - Cluster Removal

This phase is only necessary for single hub clusters.

• Remove the cluster's datasource from the central Grafana with:
  • deployer grafana central-ds remove <cluster_name>
• Run terraform plan -destroy and terraform apply from the appropriate workspace, to destroy the cluster
• Delete the terraform workspace: terraform workspace delete <NAME>
• Delete the terraform values file under the projects folder associated with the relevant cloud provider (e.g. terraform/gcp/projects/ for GCP)
• Remove the associated config/clusters/<cluster_name> directory and all its contents
• Remove the cluster from CI:
  • deploy-hubs.yaml
  • deploy-grafana-dashboards.yaml
• Remove A record from Namecheap account

...and a follow-up. Can you confirm whether we can shut down the hub and permanently delete all data, including data in user's home directories?

Best,

J.

Thanks David. I am disappointed to learn that Tufts does not plan to renew service with 2i2c.

Yes, I will be very interested to learn more about the outcomes of the pilot. Thanks in advance for sharing this information with us.

Best regards,
Jim Colliander

    Hi Jim,
    Apologies that this didn’t get followed up on sooner. We didn’t use 2i2c beyond the original contract and as of now have no plans to re-up going forward.

    I’ll follow up with our users to discuss a presentation of their findings and outcomes to share with you.    

    Best wishes,     

    David
