| 1 | //! Builds one commit of a repository and hands the result to Cloudflare, as |
| 2 | //! a preview of a pull request or as the repository's production. |
| 3 | //! |
| 4 | //! The sandbox never holds a Cloudflare credential that could touch anything |
| 5 | //! else. The deployments service opens an upload for exactly the files |
| 6 | //! this build produced and gives back a key that can only upload those; |
| 7 | //! the sandbox uploads them with it, and sends the Worker's code to the |
| 8 | //! service, which puts the app in place. |
| 9 | //! |
| 10 | //! What gets built: |
| 11 | //! |
| 12 | //! - A Workers project (a `wrangler.jsonc`, `wrangler.json` or |
| 13 | //! `wrangler.toml`): bundled by `wrangler deploy --dry-run`, with its |
| 14 | //! static assets, compatibility settings and `vars`. Other bindings (D1, |
| 15 | //! KV, R2, Durable Objects…) are not provisioned yet; the deployment says |
| 16 | //! which were left out. |
| 17 | //! - A framework g1t knows (deploy/frameworks.rs: Vite, Astro, Next.js, |
| 18 | //! SvelteKit, Nuxt, Hugo, Jekyll and the rest), found by the package's |
| 19 | //! dependencies and config files: built with its own command and served |
| 20 | //! from the folder it writes. A Cloudflare adapter's Worker (Astro's |
| 21 | //! `dist/_worker.js`, SvelteKit's `.svelte-kit/cloudflare/_worker.js`) is |
| 22 | //! bundled as a Workers project's is, without a Wrangler config of its |
| 23 | //! own. A framework set up to need a server fails before anything is |
| 24 | //! installed, saying what to change. |
| 25 | //! - A container (deploy/container.rs): a project with a `Dockerfile` (or |
| 26 | //! `Containerfile`, or the path it chose) and no framework that builds a |
| 27 | //! static site or a Worker, a framework set up to need a server, or a |
| 28 | //! Node.js, Python, Go, Ruby or PHP server, for which g1t writes a |
| 29 | //! Dockerfile and shows it in the log. The image is built with Docker |
| 30 | //! and pushed to Cloudflare's registry with a push-only login the |
| 31 | //! deployments service gives this build alone, for minutes (the |
| 32 | //! `registry` step); the service runs it. |
| 33 | //! - Anything else: a static site. Its `build` script runs, and the first |
| 34 | //! of `dist`, `build`, `out`, `public`, `_site` or `.output/public` that |
| 35 | //! exists is served, or the repository itself if it has an `index.html`. |
| 36 | //! |
| 37 | //! The project's own **Build as** (`BUILD_AS`: auto, static, workers or |
| 38 | //! docker), **Dockerfile** (`DOCKERFILE`), **Build command** and **Output |
| 39 | //! directory** win over what is detected. |
| 40 | //! |
| 41 | //! Configuration comes from the environment: |
| 42 | //! |
| 43 | //! - `G1T_API`, `DEPLOY_ID`, `DEPLOY_TOKEN`: where and how to report. |
| 44 | //! - `GIT_REMOTE`, `GIT_COMMIT`, `G1T_USER`, `G1T_TOKEN`: what to check out. |
| 45 | //! - `ROOT_DIR`: where in the repository the project lives; empty for all |
| 46 | //! of it. Everything below is relative to it. |
| 47 | //! - `BUILD_COMMAND`, `OUTPUT_DIR`: the project's own choices, if any. |
| 48 | //! - `BUILD_ENV`, `BUILD_SECRETS`: JSON objects of the repository's |
| 49 | //! variables and secrets for deploy builds. Both are set for the build; |
| 50 | //! secrets' values are redacted from its log. |
| 51 | //! |
| 52 | //! From a workflow step, `g1t-runner deploy` runs the same build in the |
| 53 | //! job's own checkout: without `GIT_REMOTE` nothing is cloned, and the |
| 54 | //! project is the current directory (`ROOT_DIR` below it). The build's id |
| 55 | //! and token come from `POST /repos/{owner}/{repo}/deployments/builds`, |
| 56 | //! which the `g1t/deploy` action calls (actions/deploy). Its output goes |
| 57 | //! to the step's log as well as the deployment's. `g1t-runner detect` |
| 58 | //! says what the build would find, as `key=value` lines for |
| 59 | //! `$GITHUB_OUTPUT`, without building anything. |
