The agent-facing flow is identical on both — only the +cluster substrate and the upgrade mechanism differ. + +## How it works + +- **Infrastructure** provisions a cluster at a **start** version and seeds a **local bare git + repo** (`~/migration-repo-.git`, run-unique so concurrent runs don't collide; + the prompt uses `{{CLUSTER_NAME}}`) with application manifests that use deprecated APIs + (`networking.k8s.io/v1beta1` Ingress, `policy/v1beta1` PodDisruptionBudget). The repo is the + agent's source of truth — there is no mock audit script and nothing names the deprecations + in-cluster; the agent must discover them itself. +- **The agent** clones the repo, audits the manifests with a real tool of its choice (e.g. + `pluto`, `kubent`, or `kubectl` dry-run/convert), migrates the deprecated resources to stable + APIs, commits/pushes, validates on the target version, applies, upgrades the cluster, and + writes `production-readiness.md`. + +## Shared setup (run on the GCE VM) + +As with cp-recovery, the eval, the cluster, and the agent must be co-located, so run on the +runner VM. Prereqs (one-time): + +- Docker (running), `kind`, `kubectl`, `tofu`, and the `oc` binary at `~/bin/oc`. +- Python ≥ 3.10 with a venv: `python3 -m venv .venv && source .venv/bin/activate && pip install -r requirements.txt`. +- Host tuning for multi-node/extra kind clusters (the agent creates a temporary validation cluster): + ```bash + echo -e "fs.inotify.max_user_watches=524288\nfs.inotify.max_user_instances=512" | sudo tee /etc/sysctl.d/99-kind.conf + sudo sysctl --system + ``` +- ≥ 50 GB disk (the agent may run two kind clusters at once — prod + validation). + +```bash +ssh @ +cd ~/devops-bench && git checkout complextask2 && git pull +source .venv/bin/activate +``` + +## Run on kind (default) + +```bash +export CLUSTER_NAME="migration-kind" # used as the kind cluster name +export NAMESPACE="migration" +export PROJECT_ID="local-kind" # Required by the harness validator; use any dummy string for local runs + +export BENCH_AGENT_TYPE="cli" +export AGENT_TARGET="oc" +export AGENT_PROVIDER="google" +export AGENT_MODEL="gemini-3.1-pro-preview" +export AGENT_API_KEY="" +export JUDGE_PROVIDER="google" +export JUDGE_MODEL="gemini-3.1-pro-preview" +export JUDGE_API_KEY="" + +python -m devops_bench tasks/common/migration-and-upgrade/task.yaml +``` + +On kind, "upgrade" is reframed: the agent validates the migrated manifests on a temporary kind +cluster it creates at the target version (kind has no in-place managed upgrade). + +## Run on GKE (real managed upgrade) + +Point the task at the GKE stack and provide real GCP credentials. + +### One-time IAM prerequisite (must be done by a project admin) + +On the runner VM, `tofu` authenticates as the VM service account +(`openclaw-vm-sa@.iam.gserviceaccount.com`). Provisioning a self-contained GKE +environment (cluster + node SA + IAM bindings + firewall) requires broad rights that this SA +does **not** have by default. These grants **cannot** be automated in the stack — the stack +itself defines IAM bindings, so it can't run until the SA already has `setIamPolicy` +(chicken-and-egg). A project Owner/IAM-admin must grant them once, out-of-band (e.g. from Cloud +Shell), **not** from the VM: + +```bash +PROJECT= +SA=openclaw-vm-sa@${PROJECT}.iam.gserviceaccount.com +for role in \ + roles/container.admin \ + roles/iam.serviceAccountAdmin \ + roles/iam.serviceAccountUser \ + roles/resourcemanager.projectIamAdmin \ + roles/compute.admin ; do + gcloud projects add-iam-policy-binding "$PROJECT" \ + --member="serviceAccount:$SA" --role="$role" +done +``` + +(The kind path needs none of this.) + +> **Gotcha — `container.admin` gets stripped by teardown.** The shared GKE module grants +> `roles/container.admin` to the same VM SA that `tofu` runs as, and manages it as a +> `google_project_iam_member`. Because that's the *same* IAM binding your bootstrap grant +> creates, `tofu destroy` (teardown) **deletes it** — so the next run starts without it, +> re-creates it mid-`apply`, and then hits GKE's IAM propagation lag → a +> `container.clusters.create` 403. To make runs repeatable, grant the SA a create-capable role +> the stack does **not** manage, so teardown can't strip it: +> ```bash +> gcloud projects add-iam-policy-binding "$PROJECT" \ +> --member="serviceAccount:$SA" --role="roles/container.clusterAdmin" +> ``` +> After any fresh IAM grant, **wait ~10 min for propagation** before running, or cluster +> creation may still 403. + +```bash +# INFRA_PROVIDER is the whole switch: the stack is provider-parameterized, and the +# env var outranks the task's own `provider: "kind"`.

Check the current set and update the + default accordingly: + ```bash + gcloud container get-server-config --zone "$GCP_LOCATION" --format="yaml(channels)" + ``` + (If a bare minor like `1.33` is rejected by the default version set, pin a full version such + as `1.33.12-gke.1059000`.) +- Running on the VM is recommended even for GKE, because the agent still uses local `kind` for + the cheap target-version validation.
