[Launch] Create the git store namespaces and the fallback host #131

Closed as not plannedsyntaqx opened this chore

The code for sharding repositories across git store namespaces (#20) and for serving a namespace from the self-hosted git store (#25) is built (e3491135). What is left is the infrastructure:

  • Make the extra Artifacts namespaces (for example g1t-us-1, and g1t-eu with an EU jurisdiction; a namespace's jurisdiction is set when it is made).
  • Add them as bindings in services/repos/wrangler.jsonc (GITSTORE_1, GITSTORE_EU, …) and name them in GITSTORE_NAMESPACES; set GITSTORE_NEW_REPOS and GITSTORE_EU_NAMESPACE.
  • Run scripts/ops/gitstore-namespaces.mjs to see each namespace and queue any moves.
  • Stand up the fallback git store (deploy/self-host/gitstore) on a persistent-disk host.
  • Rehearse the outage runbook once: scripts/ops/restore-to-gitstore.mjs restore, the repos Worker's GIT_FALLBACK_NAMESPACES secret, then reconcile and switch back.

Definition of done

  • New repositories land in more than one namespace, an EU workspace's land in the EU namespace, and a fallback rehearsal has served a namespace read-only and switched back.

Not needed yet: one namespace carries today's load. The code is built (e3491135); when it is needed, the steps above and the runbook in CONTRIBUTING.md (Operating g1t.sh) cover it.
