Implement actions (#21937) Close #13539. Co-authored by: @lunny @appleboy @fuxiaohei and others. Related projects: - https://gitea.com/gitea/actions-proto-def - https://gitea.com/gitea/actions-proto-go - https://gitea.com/gitea/act - https://gitea.com/gitea/act_runner ### Summary The target of this PR is to bring a basic implementation of "Actions", an internal CI/CD system of Gitea. That means even though it has been merged, the state of the feature is **EXPERIMENTAL**, and please note that: - It is disabled by default; - It shouldn't be used in a production environment currently; - It shouldn't be used in a public Gitea instance currently; - Breaking changes may be made before it's stable. **Please comment on #13539 if you have any different product design ideas**, all decisions reached there will be adopted here. But in this PR, we don't talk about **naming, feature-creep or alternatives**. ### ⚠️ Breaking `gitea-actions` will become a reserved user name. If a user with the name already exists in the database, it is recommended to rename it. ### Some important reviews - What is `DEFAULT_ACTIONS_URL` in `app.ini` for? - https://github.com/go-gitea/gitea/pull/21937#discussion_r1055954954 - Why the api for runners is not under the normal `/api/v1` prefix? - https://github.com/go-gitea/gitea/pull/21937#discussion_r1061173592 - Why DBFS? - https://github.com/go-gitea/gitea/pull/21937#discussion_r1061301178 - Why ignore events triggered by `gitea-actions` bot? - https://github.com/go-gitea/gitea/pull/21937#discussion_r1063254103 - Why there's no permission control for actions? - https://github.com/go-gitea/gitea/pull/21937#discussion_r1090229868 ### What it looks like <details> #### Manage runners <img width="1792" alt="image" src="https://user-images.githubusercontent.com/9418365/205870657-c72f590e-2e08-4cd4-be7f-2e0abb299bbf.png"> #### List runs <img width="1792" alt="image" src="https://user-images.githubusercontent.com/9418365/205872794-50fde990-2b45-48c1-a178-908e4ec5b627.png"> #### View logs <img width="1792" alt="image" src="https://user-images.githubusercontent.com/9418365/205872501-9b7b9000-9542-4991-8f55-18ccdada77c3.png"> </details> ### How to try it <details> #### 1. Start Gitea Clone this branch and [install from source](https://docs.gitea.io/en-us/install-from-source). Add additional configurations in `app.ini` to enable Actions: ```ini [actions] ENABLED = true ``` Start it. If all is well, you'll see the management page of runners: <img width="1792" alt="image" src="https://user-images.githubusercontent.com/9418365/205877365-8e30a780-9b10-4154-b3e8-ee6c3cb35a59.png"> #### 2. Start runner Clone the [act_runner](https://gitea.com/gitea/act_runner), and follow the [README](https://gitea.com/gitea/act_runner/src/branch/main/README.md) to start it. If all is well, you'll see a new runner has been added: <img width="1792" alt="image" src="https://user-images.githubusercontent.com/9418365/205878000-216f5937-e696-470d-b66c-8473987d91c3.png"> #### 3. Enable actions for a repo Create a new repo or open an existing one, check the `Actions` checkbox in settings and submit. <img width="1792" alt="image" src="https://user-images.githubusercontent.com/9418365/205879705-53e09208-73c0-4b3e-a123-2dcf9aba4b9c.png"> <img width="1792" alt="image" src="https://user-images.githubusercontent.com/9418365/205879383-23f3d08f-1a85-41dd-a8b3-54e2ee6453e8.png"> If all is well, you'll see a new tab "Actions": <img width="1792" alt="image" src="https://user-images.githubusercontent.com/9418365/205881648-a8072d8c-5803-4d76-b8a8-9b2fb49516c1.png"> #### 4. Upload workflow files Upload some workflow files to `.gitea/workflows/xxx.yaml`, you can follow the [quickstart](https://docs.github.com/en/actions/quickstart) of GitHub Actions. Yes, Gitea Actions is compatible with GitHub Actions in most cases, you can use the same demo: ```yaml name: GitHub Actions Demo run-name: ${{ github.actor }} is testing out GitHub Actions 🚀 on: [push] jobs: Explore-GitHub-Actions: runs-on: ubuntu-latest steps: - run: echo "🎉 The job was automatically triggered by a ${{ github.event_name }} event." - run: echo "🐧 This job is now running on a ${{ runner.os }} server hosted by GitHub!" - run: echo "🔎 The name of your branch is ${{ github.ref }} and your repository is ${{ github.repository }}." - name: Check out repository code uses: actions/checkout@v3 - run: echo "💡 The ${{ github.repository }} repository has been cloned to the runner." - run: echo "🖥️ The workflow is now ready to test your code on the runner." - name: List files in the repository run: | ls ${{ github.workspace }} - run: echo "🍏 This job's status is ${{ job.status }}." ``` If all is well, you'll see a new run in `Actions` tab: <img width="1792" alt="image" src="https://user-images.githubusercontent.com/9418365/205884473-79a874bc-171b-4aaf-acd5-0241a45c3b53.png"> #### 5. Check the logs of jobs Click a run and you'll see the logs: <img width="1792" alt="image" src="https://user-images.githubusercontent.com/9418365/205884800-994b0374-67f7-48ff-be9a-4c53f3141547.png"> #### 6. Go on You can try more examples in [the documents](https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions) of GitHub Actions, then you might find a lot of bugs. Come on, PRs are welcome. </details> See also: [Feature Preview: Gitea Actions](https://blog.gitea.io/2022/12/feature-preview-gitea-actions/) --------- Co-authored-by: a1012112796 <1012112796@qq.com> Co-authored-by: Lunny Xiao <xiaolunwen@gmail.com> Co-authored-by: delvh <dev.lh@web.de> Co-authored-by: ChristopherHX <christopher.homberger@web.de> Co-authored-by: John Olheiser <john.olheiser@gmail.com>
