In `@docs/source/getting-started/configuration/authentication.md`:
- Line 163: Update the Kubernetes secret creation instructions to avoid passing
the GitHub client secret through `--from-literal`; use `--from-file` with a
permission-restricted secret file instead, keeping the existing `client-secret`
key.
- Line 315: Add a Service manifest named dex in the dex namespace alongside the
Dex deployment manifests, selecting pods with app: dex and exposing port 5556 to
their named http target port so the Route has a backend in a fresh deployment.

Add step-by-step guide for setting up Dex with GitHub as the identity provider, including: - Creating a GitHub OAuth App with correct callback URL - Deploying Dex with the GitHub connector (org-restricted) - Kubernetes manifests for RBAC, deployment, and OpenShift Route - Configuring the Jumpstarter CR with autoProvisioning - Note about public client redirectURIs and RFC 8252 Rename the existing Dex section to 'Dex with Kubernetes Service Accounts' to distinguish the two use cases.

nit: I saw coderabbit also commented on that but maybe worth include the service manifest as well, other than that looks good.
uhh good catch, I will add it. I also keep thinking that it could be worth managing our our dex in front of authentications managed from the operator, as argocd does. This at some point would allow us to integrate auth to many other systems (including openshift itself) much easier. |
Add the missing dex Service manifest so the Route has a backend, and note the --from-file alternative for the client secret while keeping --from-literal as the default for UX. Assisted-by: OpenCode Co-Authored-By: Qwen 3.8 27B <noreply@qwen.ai>
…ges (jumpstarter-dev#1123) ## Summary Docs-only PRs (e.g. jumpstarter-dev#1119) were still triggering the E2E and Python test suites. `dorny/paths-filter` defaults to the `some` quantifier, where a negated pattern matches every file it does **not** cover — so `!python/**/*.md` "matched" docs files and the `!docs/**` exclusion was a no-op. - Set `predicate-quantifier: some-with-excludes` in `e2e.yaml` and `python-tests.yaml` so negated patterns actually exclude. - Flipped the e2e filter (per review) to `**` with exclusions for `!docs/**`, `!**/*.md`, `!**/*.mdc` and `!.devcontainer/**`: the suite exercises the whole stack, so a positive path list keeps missing code directories — this also fixes the missing `rust/**` and `protocol/**` coverage in one go. - `python-tests.yaml` keeps its positive `python/**` scope: python tests only depend on the python package. Verified by replicating the action's filter logic (picomatch, pinned commit): docs-only, `*.md`, `*.mdc` and `.devcontainer` changes excluded; controller/e2e/python/rust/protocol/Makefile/workflow changes still trigger.
