Renovate Bot#

Renovate is deployed for the Git hosting instance and runs daily; bot identity and token setup are complete.

Resource sizing#

Renovate is bursty during dependency lookups but idle otherwise. Start with requests: cpu=250m, memory=256Mi and limits: cpu=1, memory=1Gi to keep runs predictable without starving neighbors. Adjust upward if jobs overlap or CPU throttles; shrink if the cluster is tight and runs still finish on time.

Access tokens#

Use a dedicated Renovate bot user with a personal access token. Add the bot as a member to every group Renovate should scan (required so APIs list the projects). Grant api; add read_registry only if registry access is needed. Store the token in a SOPS-encrypted Secret and inject it via env in the CronJob.

Using Renovate#

To enable Renovate on a repository, add the renovate-bot user to the containing group (preferred) or directly to the project with at least Developer access; Maintainer may be required for auto-merge flows. Then commit a renovate.json to the default branch. A minimal starter config is:

{
  "extends": [
    "local>my-org/renovate/default"
  ]
}

Pointers#

Future improvements#

  • Add basic monitoring/alerting for Renovate CronJob failures and authentication errors.

  • Establish a token rotation strategy for Renovate bot users.

  • Ensure clear separation so multiple Renovate instances never overlap on the same namespaces/projects.

  • Add security hardening: minimal permissions for Renovate bot users, namespace-scoped tokens, and restricted network access.
