Certificate, secret and access-management standards — cert-manager with ACME (HTTP-01/DNS-01) or Vault PKI, certificate-expiry alerting, External Secrets Operator with Key Vault/Secrets Manager/Vault, SOPS and Sealed Secrets, secret-leak prevention (gitleaks), workload identity, least-privilege and just-in-time access for humans, and read-only identities for AI agents. Use whenever handling TLS certificates, Kubernetes secrets, credentials, IAM/RBAC grants, access to clusters or cloud…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# PKI, secrets & access standards
<!-- devops-ai-kit · Last reviewed: 2026-10-28 -->
## 1. Certificates
- **MUST** TLS certificates in the cluster are managed by cert-manager (ACME / Let's Encrypt ClusterIssuer, or Vault PKI / an internal CA). For new setups, do not create certificates by hand and paste them into a Secret. If an old system already does this, write a recommendation to migrate.
- Choosing the ACME challenge:
- HTTP-01: simple, needs a public endpoint.
- DNS-01: needed for wildcards or internal endpoints; the DNS credential must be limited to the right zone.
- **SHOULD** Test new setups with Let's Encrypt **staging** first, so you do not hit the production rate limits.
- **MUST** Expiry alerts:
- Certificates managed by cert-manager: `certmanager_certificate_expiration_timestamp_seconds - time() < 15 * 86400`, plus an alert when `certmanager_certificate_ready_status{condition="False"} == 1`.
- Certificates outside cert-manager (cloud LB, external services): blackbox exporter with `probe_ssl_earliest_cert_expiry`.

How to install
mdr add hoangminhung/devops-ai-kit/pki-secrets@sha256:1044dab8352a4615The line at the top of this page pins the label git:20261101.8158acd, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
