With the upgrade of our GKE clusters to v1.31 (#26078), [Cgroup v1 becomes deprecated](https://kubernetes.io/blog/2024/08/13/kubernetes-v1-31-release/#cgroup-v1-enters-the-maintenance-mode) and we need to switch fully to Cgroup v2. We have already replaced several node pools with new ones with Cgroup v2 for the work on Gitaly in Kubenetes, we need to find the remaining ones and replace them all too. **Scope**: - [x] Inventory remaining node pools with Cgroup v1 in each GKE cluster - [x] Replace each one with a new one (they will automatically be using Cgroup v2) ### GKE clusters - [x] `gitlab-analysis-gke-prod` (`gitlab-analysis`, `us-east1`) - [x] `gastg-gitlab-analysis-staging` (`gitlab-analysis`, `us-east1`) - [x] `db-benchmarking-gitlab-gke` (`gitlab-db-benchmarking`, `us-east1`) - [x] `ops-central` (`gitlab-ops`, `us-central1`) - [x] `ops-gitlab-gke` (`gitlab-ops`, `us-east1`) - [x] `pre-gitlab-gke` (`gitlab-pre`, `us-east1`) - [x] `gprd-us-east1-b` (`gitlab-production`, `us-east1-b`) - [x] `gprd-us-east1-c` (`gitlab-production`, `us-east1-c`) - [x] `gprd-us-east1-d` (`gitlab-production`, `us-east1-d`) - [x] `gitlab-3okls` (`gitlab-production`, `us-east1`) - [x] `gprd-gitlab-gke` (`gitlab-production`, `us-east1`) - [x] `release-gitlab-gke` (`gitlab-release`, `us-east1`) - [x] `gstg-us-east1-b` (`gitlab-staging-1`, `us-east1-b`) - [x] `gstg-us-east1-c` (`gitlab-staging-1`, `us-east1-c`) - [x] `gstg-us-east1-d` (`gitlab-staging-1`, `us-east1-d`) - [x] `gitlab-36dv2` (`gitlab-staging-1`, `us-east1`) - [x] `gstg-gitlab-gke` (`gitlab-staging-1`, `us-east1`) - [x] `prdsub-customers-gke` (`gitlab-subscriptions-prod`, `us-east1`) - [x] `stgsub-customers-gke` (`gitlab-subscriptions-staging`, `us-east1`) - [x] `stgsub-ref-customers-gke` (`gitlab-subscriptions-stg-ref`, `us-east1`) ### Node pools to replace - [x] `db-benchmarking-gitlab-gke` / `generic-2` (project: `gitlab-db-benchmarking`, location: `us-east1`) - [x] `ops-central` / `default-n2d-2` (project: `gitlab-ops`, location: `us-central1`) - [x] `ops-central` / `generic-spot-1` (project: `gitlab-ops`, location: `us-central1`) - [x] `ops-central` / `runner-1` (project: `gitlab-ops`, location: `us-central1`) - [x] `ops-gitlab-gke` / `default-n2d-2` (project: `gitlab-ops`, location: `us-east1`) - [x] `ops-gitlab-gke` / `generic-spot-1` (project: `gitlab-ops`, location: `us-east1`) - [x] `ops-gitlab-gke` / `n2d-highmem-2` (project: `gitlab-ops`, location: `us-east1`) - [x] `ops-gitlab-gke` / `vault-3` (project: `gitlab-ops`, location: `us-east1`) - [x] `gprd-gitlab-gke` / `generic-1` (project: `gitlab-production`, location: `us-east1`) - [x] `gprd-gitlab-gke` / `generic-2` (project: `gitlab-production`, location: `us-east1`) - [x] `gprd-gitlab-gke` / `generic-mem-3` (project: `gitlab-production`, location: `us-east1`) - [x] `gprd-gitlab-gke` / `redis-registry-cache-0` (project: `gitlab-production`, location: `us-east1`) - [x] `gprd-us-east1-b` / `generic-1` (project: `gitlab-production`, location: `us-east1-b`) - [x] `gprd-us-east1-b` / `generic-2` (project: `gitlab-production`, location: `us-east1-b`) - [x] `gprd-us-east1-b` / `generic-mem-3` (project: `gitlab-production`, location: `us-east1-b`) - [x] `gprd-us-east1-c` / `generic-1` (project: `gitlab-production`, location: `us-east1-c`) - [x] `gprd-us-east1-c` / `generic-2` (project: `gitlab-production`, location: `us-east1-c`) - [x] `gprd-us-east1-c` / `generic-mem-3` (project: `gitlab-production`, location: `us-east1-c`) - [x] `gprd-us-east1-d` / `generic-1` (project: `gitlab-production`, location: `us-east1-d`) - [x] `gprd-us-east1-d` / `generic-2` (project: `gitlab-production`, location: `us-east1-d`) - [x] `gprd-us-east1-d` / `generic-mem-3` (project: `gitlab-production`, location: `us-east1-d`) - [x] `release-gitlab-gke` / `generic-2` (project: `gitlab-release`, location: `us-east1`) - [x] `gstg-gitlab-gke` / `generic-1` (project: `gitlab-staging-1`, location: `us-east1`) - [x] `gstg-gitlab-gke` / `generic-2` (project: `gitlab-staging-1`, location: `us-east1`) - [x] `gstg-gitlab-gke` / `generic-mem-1` (project: `gitlab-staging-1`, location: `us-east1`) - [x] `gstg-gitlab-gke` / `redis-registry-cache-0` (project: `gitlab-staging-1`, location: `us-east1`) - [x] `prdsub-customers-gke` / `default-1` (project: `gitlab-subscriptions-prod`, location: `us-east1`) - [x] `stgsub-customers-gke` / `default-1` (project: `gitlab-subscriptions-staging`, location: `us-east1`) - [x] `stgsub-ref-customers-gke` / `default-1` (project: `gitlab-subscriptions-stg-ref`, location: `us-east1`)
