Use when cert-manager does not issue or renew a certificate in Kubernetes: a Certificate that stays READY False, a CertificateRequest that is Pending, Denied or Failed, an Issuer or ClusterIssuer that is not Ready ("Error getting keypair for CA issuer"), "Referenced \"Issuer\" not found", ACME Orders or Challenges stuck pending (HTTP-01, DNS-01, rate limits), a certificate that expired or did not renew, or "failed calling webhook \"webhook.cert-manager.io\"" when applying resources.…
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
# cert-manager troubleshooting Find out why cert-manager does not issue or renew a certificate, and propose a fix. **Read first, ask before changing.** Run the investigation commands freely. Run a command under an "Ask first" line only after the user approves that exact command; if your credentials do not allow it, give it to the user to run. Never run a "Proposed fix"; hand it to the user. cert-manager works in a chain. A **Certificate** says what is wanted. cert-manager creates a **CertificateRequest** for each issuance, which an **Issuer** (one namespace) or **ClusterIssuer** (whole cluster) signs. For ACME issuers (Let's Encrypt and others) the request also gets an **Order** with one **Challenge** per domain. Follow the chain from the Certificate and stop at the first object that is not Ready. The commands use placeholders: `my-namespace`, `my-app-tls` (the Certificate), `my-issuer` and `my-cluster-issuer`. Replace them with the real names. The `cert-manager` namespace and Deployment names are those of the default install; a Helm install may use other names (find them with the first command of step 5). …

How to install
mdr add k8s-servant/k8s-skills/k8s-cert-manager-troubleshooting@sha256:c98fe3ca0d53975bThe line at the top of this page pins the label git:20261024.482781a, 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.
