Operations runbook — Secret rotation

Zero-downtime credential rotation for the AlphaSwarm control plane + workloads.

What's a secret here?​

Every entry in alphaswarm_platform/deployments/compose/.env.schema with classification: secret or classification: rotation-required. The rotation-required ones (e.g. AUTH0_M2M_CLIENT_SECRET) should be rotated on a fixed schedule (typically 90 days).

Pre-flight​

  1. Confirm at least one operator with admin:cluster is online to handle Auth0 console operations.
  2. Check kubectl -n alphaswarm rollout status deployment/alphaswarm-core — if it's currently degraded, fix that first.
  3. Verify the secret store you're rotating into is reachable (Vault sealed?, SSM blocked by SCP?, etc.).

Procedure — Auth0 M2M client secret​

  1. Mint a new secret in Auth0: Applications → alphaswarm-m2m → Settings → "Rotate" (Auth0 keeps the old one valid for 24h by default).

  2. Update the secret store:

    # Vault example
    vault kv patch secret/alphaswarm/auth0 m2m_client_secret=<new-value>

  3. Reload the relevant pods:

    kubectl -n alphaswarm rollout restart deployment/alphaswarm-core
    kubectl -n alphaswarm rollout restart deployment/alphaswarm-worker
    kubectl -n alphaswarm-admin rollout restart deployment/alphaswarm-cp

  4. Verify: curl https://manage.alphaswarm.enterprise.com/manage/health returns 200; the audit log shows successful M2M token mints.

  5. Revoke the old secret: Auth0 → alphaswarm-m2m → "Revoke previous secret" once you're confident every pod has rolled.

Procedure — Postgres password​

  1. Connect via the old credential and create the new password:

    ALTER USER alphaswarm WITH PASSWORD 'new-strong-password';

  2. Update the secret store (same as above).

  3. Rolling restart of every service that talks to Postgres: alphaswarm-core, alphaswarm-worker, alphaswarm-cp. Each pod re-reads the env var on startup.

  4. No old-credential revocation needed — Postgres only honours the current password.

Procedure — Session cookie secret​

The session cookie secret (ALPHASWARM_SESSION_COOKIE_SECRET) is used to encrypt the alphaswarm_session cookie. Rotating it invalidates every active session.

  1. Generate: python -c "import secrets; print(secrets.token_urlsafe(64))"
  2. Update the secret store.
  3. Rolling restart of alphaswarm-core only. Users will be redirected to Auth0 to re-authenticate.

Procedure — SCIM bearer token​

The SCIM bearer token hash gates the /scim/v2/* endpoint.

  1. Generate a new random token: python -c "import secrets; print(secrets.token_urlsafe(48))"
  2. Compute its SHA-256 hash: python -c "import hashlib, sys; print(hashlib.sha256(sys.argv[1].encode()).hexdigest())" <new-token>
  3. Update ALPHASWARM_AUTH_SCIM_BEARER_TOKEN_HASH in the secret store with the hash.
  4. Update the IdP's SCIM provisioning configuration with the new RAW token.
  5. Rolling restart of alphaswarm-core.

Auditing​

Every secret rotation should leave a trace:

  • The secret store records the change (Vault audit log / Cloudtrail / Cloud Audit Logs)
  • The application's audit log shows the M2M / Postgres / cookie events
  • alphaswarm_controller's WorkloadRun ledger records the rotation request

If you can't see all three, file an incident — silent rotations are a security smell.
