## Why Deploy `goodtune/ghp` (a GitHub proxy) so estate agents have a controlled GitHub access path. Mirrors the artifactapi app structure and the estate's templated `default` Vault convention. ## How (this PR) - Namespace `ghp`. Runs as the namespace's auto-created `default` ServiceAccount (no custom SA). - CNPG `Cluster` (named `postgres`, db/owner `ghp`) + dedicated `cnpg-ghp` Ceph RGW backup bucket + nightly ScheduledBackup. - Deployment `command: ["/ghp","serve"]`; `GHP_DATABASE_DSN` assembled from the CNPG-generated `postgres-app` Secret via `$(VAR)` expansion pointing at `postgres-rw.ghp.svc`. - **Sync-phase migrate hook Job** `ghp-migrate` (`/ghp migrate`) at sync-wave 1 so serve replicas never race migrations. - VSO wiring on the templated `default` role: `VaultAuth` role/SA `default`; `VaultStaticSecret`s source `kv/kubernetes/namespace/ghp/default/github-app` → Secret `ghp-github-app` and `kv/kubernetes/namespace/ghp/default/app` → Secret `ghp-app`. `private_key` mounted as a file; `encryption_key` → `GHP_ENCRYPTION_KEY`. - cert-manager `Certificate` `ghp-tls` off ClusterIssuer `vault-issuer`, SANs github.com/api.github.com/codeload.github.com/*.githubcopilot.com/ghp.k8s.syd1.au.unkin.net; mounted for `GHP_TLS_CERT_FILE`/`GHP_TLS_KEY_FILE`. - Service (443->8443, 80->8080, metrics 9136), PDB, VMServiceScrape, internal Traefik Gateway + HTTPRoute for `ghp.k8s.syd1.au.unkin.net`. - Sync-wave ordering: DB + VSO/cert (wave 0, wait Healthy) -> migrate Job (wave 1) -> serve Deployment + Service/Gateway/HTTPRoute (wave 2). Writable `/tmp` emptyDir on both pods (root FS is read-only). - Registered in the `platform` ApplicationSet + AppProject. - Validation: `kustomize build` clean, kubeconform 17/17 valid (0 skipped), yamllint + pre-commit clean. ## NOTE — prerequisites before ghp goes Healthy - **`GHP_ADMINS` placeholder**: `apps/base/ghp/configmap.yaml` has `GHP_ADMINS: "REPLACE_ME_ben_github_username"` — set it to Ben's GitHub username. - Ben's GitHub-App runbook + kv population at the templated paths `kv/kubernetes/namespace/ghp/default/github-app` (app_id/client_id/client_secret/private_key) and `kv/kubernetes/namespace/ghp/default/app` (encryption_key). - tf-artifactapi #25: the `ghcr` remote pattern for pulling `ghcr/goodtune/ghp`. - **No terraform-vault change needed** — the estate's templated `default` policy already grants read on `kv/kubernetes/namespace/<ns>/default/*` (the bespoke ghp role PR terraform-vault#120 is closed). - DNS overrides (pointing github.com etc. at ghp) are intentionally **out of scope** — separate deferred bind-operator PR. Assumptions flagged: metrics env var `GHP_METRICS_LISTEN`; two Secrets (`ghp-github-app` + `ghp-app`) rather than one merged Secret; DSN assumes the CNPG-generated password is URL-safe.
