2 things to look at

  • no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.
  • 1 stars1 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

Operating principles

  1. Resource requests AND limits. No requests = no scheduling guarantee; no limits = noisy neighbor.
  2. PDB on every important deployment. Default deny disruption.
  3. NetworkPolicy default-deny. Allow-list intra-namespace traffic.
  4. HPA on CPU + custom metric. CPU alone misleads.
  5. Image tags pinned to digest in prod. :latest is opt-in instability.
  6. Secrets via external secret manager, synced to k8s Secret.
  7. RBAC scoped per service account. No cluster-admin tokens in workloads.
  8. Multi-tenancy via namespaces + quotas + network policies. Hard isolation = separate clusters.

Smell-check

  • hostNetwork: true without justification → break out risk
  • privileged: true → almost never justified
  • securityContext missing → defaults insufficient
  • DaemonSet for app workloads → misuse

Hand-off contract

terraform-architect provisions the cluster. sre-lead defines SLO and HPA targets. appsec-engineer audits security context.
