变更内容

  • 新增 GitHub Actions 工作流,将以下 Docker 镜像自动构建并发布到 GitHub Container Registry:
    • ghcr.io/hydro-dev/hydro-backend
    • ghcr.io/hydro-dev/hydro-judge
  • 支持在以下场景触发镜像发布:
    • 推送到 master 分支
    • 推送 v* 格式的版本标签
    • 手动触发工作流
  • 使用 Docker Buildx、QEMU 和 GitHub Actions Cache 优化镜像构建流程。
  • 更新 Docker Compose 配置,改为直接使用 GHCR 中的镜像,不再在本地构建镜像。
  • 为后端和评测服务添加无限制的 stack ulimit,避免部分场景下的栈大小限制问题。

更新后的 Docker Compose 会使用以下镜像:

ghcr.io/hydro-dev/hydro-backend:latest
ghcr.io/hydro-dev/hydro-judge:latest

测试情况

  • 已检查 Docker Compose 配置变更。
  • 已配置后端和评测服务的 GHCR 镜像构建与发布流程。
  • 建议在合并前验证:
    • GitHub Actions 是否能够成功构建并推送两个镜像;
    • 使用 docker compose up -d 是否能够正常启动所有服务;
    • Judge 服务是否能够正常连接后端并执行评测。

Summary by CodeRabbit

  • Deployment Updates
    • Backend and judge container images are now published automatically for master-branch updates and version releases, with manual publishing also available.
    • Docker Compose deployments now use the published images and check for updated versions whenever services start.
    • Stack limits for both services are now unlimited.

Walkthrough

A new GitHub Actions workflow builds and publishes backend and judge Docker images to GHCR on pushes to master, version tags matching v*, and manual runs. Docker Compose now pulls the published latest images for both services and sets their soft and hard stack limits to -1.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Feature

Merge Risk: 🟡 Moderate · up to 8cdc3

Docker deployments now pull prebuilt images from GHCR instead of building locally. These images are currently not anonymously pullable, so a fresh install following the documented steps would fail to start. Make the packages public or document the required authentication before merging. Also stop version-tag builds from overwriting the latest images.

the GHCR packages anonymously accessible or by configuring deployment
authentication. Preserve the documented `docker-compose up -d` startup flow.

<title>Better document `latest` tag (`flavor.latest=auto` default vs `type=raw,value=latest`)</title>
<location>GitHub issue 593 in docker/metadata-action (link omitted to avoid creating a cross-reference)</location>
<excerpt># Better document `latest` tag (`flavor.latest=auto` default vs `type=raw,value=latest`) ... - `type=raw,value=latest,enable=false` does not prevent the `latest` tag from being added by default. Configure the `flavor` input with `latest=false` to opt-out instead. ... ### The four tags that opt-in to `latest` tag (_and the importance of the `priority` attribute_) ... &gt; https://github.com/docker/metadata-action/issues/567#issuecomment-3579068205 &gt; &gt; --- &gt; &gt; Usage of any of these tags types will implicitly enable a `latest` tag as the docs explain when `flavor.latest=auto` would evaluate to `flavor.latest=true`: &gt; &gt; - `type=ref,event=tag` (_**source:** always `true`_) &gt; - `type=semver,pattern=...` (_**source:** `false` if pre-release or invalid semver_) &gt; - `type=pep440,pattern=...` (_**source:** `false` if pre-release or invalid pep440_) &gt; - `type=match,pattern=...` (_**source:** always `true`_) &gt; &gt; **NOTE:** &gt; - Those all rely on `github.ref_type == &`#39`;tag&`#39`;` (_a push event trigger from a tag rather than a commit_), unless they were given an explicit `value` as input instead. &gt; - `latest` will be determined by the first `tags` input entry processed by the action (_which is dependent upon the sort order based on their associated `priority` attribute_). &gt; - `type=semver` (900) / `type=pep440` (900) &gt; `type=match` (800) &gt; `type=ref` (600) &gt; - When priority is the same value, the secondary sorting factor is the declaration order from the `tags` input. &gt; - If a different tag type from those four mentioned was given a higher priority (_or already had higher by default, eg: `type=schedule` (1000)_), then that tags default `flavor.latest=auto` logic is to set `latest=false`, preventing an implicitly added a `latest` tag. ... ### Conditional logic for `type=semver`/`type=pep440` on pre-release inputs: ... &gt; https://github.com/docker/metadata-action/issues/461#issuecomment-2680849083 &gt; &gt; --- &gt; &gt; https://github.com/docker/metadata-action/blob/ed95091677497158a9ff38b314264cd965388d5e/src/meta.ts#L183-L198 &gt; &gt; 1. At the start of that snippet the `latest` variable is initially `false` and if the semver tag being processed is considered a release tag (_not parsed as a semver pre-release version_) it&`#39`;ll be set to `latest=true`. &gt; 2. Finally at the end of that snippet it&`#39`;ll check `flavor.latest`, which if configured as `auto` will use the `latest` variable (_release: `true`, or for pre-release: `false`_) that was set in the prior condition, otherwise it&`#39`;ll use what was explicitly configured on the workflow (`flavor.latest=&lt;true|false&gt;`). ... ### Influence of `flavor.latest` on creating an implicit `latest` tag (_compared to manual `type=raw,value=latest,enable= `_) ... &gt; https://github.com/docker/metadata-action/issues/461#issuecomment-2686558629 &gt; &gt; --- &gt; &gt; I&`#39`;m short on time, so here&`#39`;s a rough outline for anyone landing here, that may want to contribute a fix to the README: &gt; - `type=raw` could mention a caveat with `value=latest`. &gt; - The `latest` tag section references the default `flavor.latest=auto` behaviour. &gt; - That section then suggests using a `type=raw` tag with `enable` for controlling a conditional `latest` tag, without clarifying that the `flavor.latest=auto` default will disregard/override that enable logic. &gt; - Additionally if `flavor.latest=true` and a `type=raw,value=latest,enable=true` tag are both present, the tags output will produce two `latest` tags (_even when there is no suffix/prefix difference involved_). ... &gt; - `flavor` setting describes the `onlatest` condition for `flavor.&lt;prefix|suffix&gt;`: ... &gt; - It is not clarified that `onlatest` attribute is only applicable to an **implicit `latest` tag** generated from `flavor.latest=&lt;auto|true&gt;` (_when `auto` resolves to `true`_). `onlatest` has no relation to an explicit `type=raw,value=latest` tag (_which c…[truncated]</excerpt>

Prevent version tags from updating latest.

docker/metadata-action@v5 generates latest for type=ref,event=tag when latest=auto. The raw entry's default-branch condition does not disable this behavior. A v* tag can therefore update the image consumed by both Compose services. Set flavor: latest=false so only the conditional raw entry controls latest.

Proposed change
         with:
           images: ghcr.io/${{ env.OWNER_LC }}/${{ matrix.image }}
+          flavor: latest=false
           tags: |
             type=ref,event=branch
             type=ref,event=tag

In @.github/workflows/docker-ghcr.yml at line 57, Update the
docker/metadata-action@v5 configuration to set `flavor: latest=false`,
preventing `type=ref,event=tag` from generating the `latest` tag; leave the
conditional raw entry as the sole source of `latest`.

Make both GHCR packages anonymously pullable or configure deployment authentication.

The anonymous GHCR token request returns 403 for both hydro-backend:latest and hydro-judge:latest. Therefore, the documented docker-compose up -d command cannot start this stack on an unauthenticated host because the local build fallback was removed.

For those who mastered docker, understand the cons, can handle issues by themselves, and want to deploy in k8s or similar environments. But good call, I'm remove them later.
