Use when OPA Gatekeeper blocks, warns about or fails to police resources in Kubernetes: "admission webhook \"validation.gatekeeper.sh\" denied the request: [constraint] message", warnings from constraints in warn mode, a constraint that should block but only shows violations in audit (dryrun), a ConstraintTemplate that does not compile (ingest_error, rego_parse_error), "no matches for kind" when applying a constraint, referential policies that never fire (sync), mutations that do not apply, or…
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
# OPA Gatekeeper troubleshooting Find out why Gatekeeper denies, warns about or does not police a resource, 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. A **ConstraintTemplate** holds the policy code (Rego, or CEL under `K8sNativeValidation`) and makes Gatekeeper create a new kind in `constraints.gatekeeper.sh` (for example `K8sRequiredLabels`). A **constraint** of that kind says where the policy applies (`spec.match`), with which parameters, and what happens on a violation (`spec.enforcementAction`: `deny`, `dryrun`, `warn` or `scoped`). The admission webhook checks new requests; the **audit** checks what already exists and writes the results into each constraint's status. A constraint is a guardrail someone chose on purpose. The usual fix is to make the resource comply; changing, scoping or exempting a constraint is a decision for its owners. The commands use placeholders: `my-namespace`, `my-app`, `k8srequiredlabels` (a …

How to install
mdr add k8s-servant/k8s-skills/k8s-gatekeeper-troubleshooting@sha256:726e1c92a81d5455The line at the top of this page pins the label git:20261024.4faf836, 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.
