Updated JWT authentication to use configuration values instead of hardcoded secrets, improving security and flexibility. Enhanced CORS policy to conditionally allow origins based on configuration settings, with logging for permissive defaults. Updated README to reflect project renaming and clarify service context.

# Containerization
|
|
|
|
> **NOTE (forward-looking)**: image tag, csproj name, and entrypoint reflect the **post-rename** state. Today's `Dockerfile` ENTRYPOINT is `dotnet Azaion.Flights.dll` and the image tag base is `azaion/flights`. Renames tracked under Jira AZ-EPIC children B5 (csproj/namespace) and B10 (Dockerfile entrypoint + Woodpecker image tag).
|
|
|
|
## Source
|
|
|
|
`./Dockerfile` (single Dockerfile at the repo root). Multi-arch via build args.
|
|
|
|
## Build strategy: multi-arch from a single Dockerfile
|
|
|
|
```dockerfile
|
|
FROM --platform=$BUILDPLATFORM mcr.microsoft.com/dotnet/sdk:10.0 AS build
|
|
ARG TARGETARCH
|
|
WORKDIR /src
|
|
COPY . .
|
|
RUN arch=$([ "$TARGETARCH" = "amd64" ] && echo "x64" || echo "$TARGETARCH") && \
|
|
dotnet publish -c Release -o /app --os linux --arch $arch
|
|
|
|
FROM mcr.microsoft.com/dotnet/aspnet:10.0
|
|
ARG CI_COMMIT_SHA=unknown
|
|
ENV AZAION_REVISION=$CI_COMMIT_SHA
|
|
WORKDIR /app
|
|
COPY --from=build /app .
|
|
EXPOSE 8080
|
|
ENTRYPOINT ["dotnet", "Azaion.Missions.dll"] # post-B5 + B10
|
|
```
|
|
|
|
Key choices:
|
|
|
|
- **`--platform=$BUILDPLATFORM`** on the build stage — the SDK runs on the **builder's** native architecture (typically AMD64 in CI), but `dotnet publish --os linux --arch $arch` cross-publishes for the **target** architecture (`arm64` for Jetson / OPi; `amd64` for operator-PC). This avoids needing QEMU emulation for the (slow) build phase.
|
|
- **Two-stage**: SDK image (~800 MB) for the build, runtime image (`mcr.microsoft.com/dotnet/aspnet:10.0`, ~210 MB) for the published artifacts. Final image carries no SDK, no source code, no `.csproj`.
|
|
- **`AZAION_REVISION` env var** baked from `CI_COMMIT_SHA` at build time — surfaces the source commit at runtime for support / triage. Not consumed by the application code today; visible only via `docker inspect` or `env` in the running container.
|
|
- **`EXPOSE 8080`** matches the ASP.NET Core default (no `ASPNETCORE_URLS` override) and the edge compose port mapping `5002:8080`.
|
|
|
|
## What the Dockerfile does **NOT** do (carry-forward improvements)
|
|
|
|
- **No `.dockerignore`** — every file under the repo root is copied into the build context, including `_docs/`, `.cursor/`, and the previously-committed `obj/` / `bin/` (cleaned by `dotnet publish` but still copied across the wire). A `.dockerignore` would shrink the build context meaningfully on Jetson-class builders. Tracked as opportunistic improvement.
|
|
- **No `HEALTHCHECK` directive** — `/health` exists in the application (Flow F7) but the container itself does not declare a healthcheck. Compose-level healthcheck is the suite's expected mechanism.
|
|
- **No non-root `USER`** — the runtime image runs as root. The `aspnet:10.0` base image supports a non-root user (`USER app`) since .NET 8; switching is a one-line change on the next refresh and would tighten container isolation.
|
|
- **No build-time test pass** — no `dotnet test` step. The repo has no test project today (tracked in `../../../suite/_docs/_process_leftovers/2026-04-22_ci-unit-test-lane-missing-projects.md`); when a `tests/Azaion.Missions.Tests/` project lands, a pre-publish `dotnet test` step is the natural next addition.
|
|
|
|
## Image lifecycle on edge devices
|
|
|
|
1. Woodpecker builds + pushes `${REGISTRY_HOST}/azaion/missions:${BRANCH}-arm` (post-B10) on every push to `dev` / `stage` / `main` (see `ci_cd_pipeline.md`).
|
|
2. Watchtower running on each edge device polls the registry; on a new digest for the device's pinned tag, it pulls and re-creates the container.
|
|
3. `flight-gate` (per `../../../suite/_docs/00_top_level_architecture.md`) prevents container restart mid-mission. Once the active mission completes, the new image becomes live.
|
|
4. Container starts → `Program.cs` → migrator → `app.Run()` (Flow F6).
|
|
|
|
## Image variants and tag strategy
|
|
|
|
| Branch | Tag (post-B10) | Audience |
|
|
|--------|----------------|----------|
|
|
| `dev` | `azaion/missions:dev-arm` | Engineers; rolling latest-dev |
|
|
| `stage` | `azaion/missions:stage-arm` | Pre-prod customer demo devices |
|
|
| `main` | `azaion/missions:main-arm` | Production edge fleets |
|
|
|
|
**No semantic version tags today** (no `v1.2.3`-style tags). Watchtower polls the named tags directly. Carry-forward improvement: add `${REGISTRY_HOST}/azaion/missions:${CI_COMMIT_SHA:0:8}-arm` alongside the branch tag so rollback to a specific build is possible without rebuilding.
|
|
|
|
## Multi-arch — current limitation
|
|
|
|
Today the Woodpecker pipeline (`ci_cd_pipeline.md`) builds **only the `arm64` variant** (the runner is ARM64-labeled and the tag suffix is `-arm`). For AMD64 (operator-PC) deployments, a second pipeline / second runner / `linux/amd64` build args would be needed. Out of this Epic — the current operator-PC deployment story uses local builds.
