feat(argocd-dex): add headlamp as a static OIDC client#12
Merged
Conversation
Register Headlamp as a Dex static client in the ArgoCD CR's dex.config so the existing GitHub OAuth flow can be reused for the upcoming Headlamp dashboard install — same pattern Grafana will move to next. Adds the client secret to argocd-secret as `dex.headlamp.clientSecret` (sops-encrypted via the existing AGE key). Generalizes the .sops.yaml encrypted_regex from `dex.github.client*` to `dex.<name>.client*` so any future Dex static clients pick up encryption automatically.

## Summary Install Headlamp as a Helm-based ArgoCD Application, fronted by the cluster-apps Cloudflare Tunnel at \`https://headlamp.makeitwork.cloud\`, with login flowing through ArgoCD's embedded Dex (which bridges to GitHub OAuth — same path Grafana will move to next). ### \`operators/headlamp/\` - **\`namespace.yaml\`** — headlamp ns. - **\`oidc-secret.yaml\`** — Secret named \`oidc\` in headlamp ns, sops-encrypted. Consumed by the upstream chart with \`config.oidc.secret.create=false, name=oidc\`. \`clientSecret\` matches the value in \`argocd-secret.dex.headlamp.clientSecret\` from the merged Dex static-client PR. - **\`ksops-headlamp-secrets.yaml\`** — pulls the secret in via KSOps. - **\`application.yaml\`** — ArgoCD Helm Application installing chart v0.41.0 from \`https://kubernetes-sigs.github.io/headlamp/\`. Cluster-admin RBAC (single-user home cluster), modest resource limits. - **\`kustomization.yaml\`** + add \`headlamp\` to \`operators/kustomization.yaml\`. ### \`workloads/headlamp/\` - **\`tunnel-binding.yaml\`** — TunnelBinding fronts headlamp Service on \`headlamp.makeitwork.cloud\` via the existing cluster-apps tunnel. ### \`workloads/apps/\` - **\`headlamp-app.yaml\`** + add to \`workloads/apps/kustomization.yaml\` — ArgoCD Application that syncs the workload manifests. ## Pairs with - tfroot-cloudflare #6 (merged) — CNAME for headlamp.makeitwork.cloud. - kustomize-cluster #12 (merged) — Headlamp registered as a Dex static client. ## Test plan - [x] After merge: \`kube-prometheus-stack\` operators app + \`headlamp\` operators app reach Synced + Healthy - [x] After merge: headlamp-app workloads app reaches Synced + Healthy - [x] After merge: \`https://headlamp.makeitwork.cloud\` redirects to ArgoCD's Dex GitHub login, then back to a working dashboard with cluster-admin scope 🤖 Generated with [Claude Code](https://claude.com/claude-code)

Summary
Register Headlamp as a Dex static client in the ArgoCD CR's `dex.config`. Reuses the existing GitHub OAuth flow that ArgoCD already runs, so we don't need a second Dex install or a second GitHub OAuth app — Dex bridges GitHub OAuth → OIDC, Headlamp consumes the OIDC.
Same wiring will land for Grafana in a small follow-up PR (replacing its built-in `GF_AUTH_GITHUB_` with `GF_AUTH_GENERIC_OAUTH_` pointing at the same Dex), per the consolidation we agreed on.
