g1t/services/deployments/src/index.ts
| 1 | /** |
| 2 | * The deployments service: a project's production, deployed from its |
| 3 | * default branch on every push, and a live preview of every branch with an |
| 4 | * open pull request, on g1t.page. |
| 5 | * |
| 6 | * It reacts to events (a pull request opened, ready, pushed to, closed or |
| 7 | * merged; a push to the default branch) for every project built from the |
| 8 | * repository, asks billing whether the workspace pays for Deployments, and |
| 9 | * asks the runner to build the commit in a sandbox. The sandbox reports |
| 10 | * back through the API with a token for that build alone; this service |
| 11 | * opens the upload of its files and puts the finished app in the Workers |
| 12 | * for Platforms namespace, where the `*.g1t.page` dispatcher finds it by |
| 13 | * hostname. |
| 14 | * |
| 15 | * Nothing here is free, and nothing is capped. On the plan, every build |
| 16 | * second is charged as it happens; requests, CPU time and custom domains |
| 17 | * are charged from the first once the month is over, all at cost plus the |
| 18 | * margin and from the plan's included usage first. No count of projects, |
| 19 | * previews or apps ever stops or pauses a workspace: apps are not metered |
| 20 | * at all. Only the workspace's spend limit pauses its apps |
| 21 | * (`holdToLimits`), and only the plan ending takes them down. A Worker |
| 22 | * runs only while it answers a request, so an app no one visits costs |
| 23 | * nothing, and a preview is taken down when its pull request closes or |
| 24 | * after its project's idle days. |
| 25 | * |
| 26 | * Reached through service bindings (`POST /rpc/<method>`) and, for a |
| 27 | * build's reports, through the API (`POST /jobs/<id>/<step>`). |
