CI & Docker

CI runs on Gitea Actions (git.unom.io, org unom). Three workflows in .gitea/workflows/, two runners, three images in the Gitea container registry.

Workflows

Dockerized pieces

The host and the native clients are intentionally not containerized (the host needs the GPU/compositor stack of the box it runs on). What is:

Registry pushes authenticate with the repo Actions secret REGISTRY_TOKEN (a PAT with write:package; the login username in docker.yml is the token owner, not the push actor).

Runners

• ubuntu-24.04 — the pre-existing Linux runner; runs the Rust/web/docs jobs (as docker containers) and the image build+push jobs.
• macos-arm64 — home-mac-mini-1 (M-series, macOS 26), a host-mode act_runner (upstream now ships it as gitea-runner) provisioned by scripts/ci/setup-macos-runner.sh: rustup (+ both darwin targets for the universal xcframework), Node.js (host-mode runners execute JS actions via node from PATH — nothing auto-provisions it), the runner binary in ~/.local/bin, state in ~/ci/act-runner/ (config, .runner registration, runner.log), kept alive by the io.gitea.act_runner root LaunchDaemon — it cannot be a user LaunchAgent: macOS Local Network privacy silently blocks LAN dials ("no route to host") from unbundled CLI binaries in gui/user launchd domains, while system daemons are exempt. Needs full Xcode for xcodebuild -create-xcframework (CLT alone only covers swift build/test); if xcode-select still points at CLT, the script auto-detects /Applications/Xcode*.app and bakes a DEVELOPER_DIR override into the daemon environment — no xcode-select -s required.

Re-provisioning (idempotent) or first-time registration from a dev box:

# token: org unom → Settings → Actions → Runners → Create new runner
ssh enricobuehler@192.168.1.135 GITEA_RUNNER_TOKEN=<token> bash -s \
    < scripts/ci/setup-macos-runner.sh

Apple releases

release.yml produces the production client builds on the Mac runner. All three app targets share the bundle ID io.unom.punktfunk (one App Store listing, universal purchase — effectively unchangeable after first submission). Secrets: DEVID_CERT_P12_B64/DEVID_CERT_PASSWORD (Developer ID Application certificate, only creatable by the account holder) and ASC_API_KEY_P8/ASC_API_KEY_ID/ASC_API_ISSUER_ID (App Store Connect API key — notarization, TestFlight upload, automatic-signing profile fetch). Signing uses a per-run throwaway keychain; nothing persists on the runner. Per-platform state:

• macOS — Developer ID export → notarytool → stapled .dmg on the Gitea release. The Mac App Store lane is deferred: it requires App Sandbox entitlements (network client + Bonjour) the app doesn't declare yet.
• iOS — archive + upload to TestFlight (method: app-store-connect, destination: upload). Crypto is declared exempt (ITSAppUsesNonExemptEncryption, Config/Info.plist) so builds don't stall on the compliance question.
• tvOS — not built: the Rust core needs tier-3 targets (nightly -Zbuild-std).

The runner needs a release (non-beta) Xcode — App Store processing rejects beta-SDK builds, and a beta is unusable for the Rust side too: a newer-than-OS ld emits dylibs the running dyld rejects ("mis-aligned LINKEDIT string pool"), killing every proc-macro build with a misleading E0463 can't find crate. build-xcframework.sh therefore resolves toolchains itself: non-beta Xcode for everything; with only CLT + a beta present it builds macOS slices against CLT (packaging via any Xcode — -create-xcframework does no linking) and refuses iOS/tvOS slices (CLT has no iOS SDK).

Deployment

docker.yml's deploy-docs job ships this docs site after every image push: it syncs compose.production.yml to ~/punktfunk-docs on unom-1 (the DMZ services VM website and cms deploy to) and runs docker compose pull && up -d there over SSH (same pattern and secret set as unom/website: DEPLOY_HOST / DEPLOY_USER / DEPLOY_PORT / DEPLOY_SSH_KEY, the unom-ci-deploy key). The container binds host port 3220; Caddy on home-reverse-proxy-1 serves it as https://docs.punktfunk.unom.io (vhost in unom/reverse-proxy, UniFi firewall allowlist Caddy→unom-1:3220 in unom/infra proxmox/unom-1). The host and the web console are NOT deployed — the console fronts a punktfunk host's management API on whatever box runs the host.

Troubleshooting

• Mac runner offline — ssh <mac> tail -50 '~/ci/act-runner/runner.log'; restart with sudo launchctl kickstart -k system/io.gitea.act_runner. "no route to host" in the log means the daemon is running in a gui/user domain again — see the Local Network note above.
• apple.yml fails at the xcframework step — Xcode missing or unselected: sudo xcode-select -s /Applications/Xcode.app/Contents/Developer and accept the license (sudo xcodebuild -license accept), then re-run.
• Rust job can't pull punktfunk-rust-ci — the runner host's docker daemon needs a docker login git.unom.io if the org/registry isn't anonymously readable.
• Stale builder image after toolchain/dep changes — docker.yml re-pushes it on every main push; a manual workflow_dispatch of docker.yml forces a rebuild.
