Team permission: any project permission. ## OpenAPI ````yaml /spec/paas.yaml get /v2/projects/{project_id}/logs/chart openapi: 3.0.1 info: title: Apps & Deployments version: 1.0.0 description: > Create apps, deploy them, change their plans and settings, and read their logs, metrics and events. ## Identifying an app Most endpoints identify an app by its **name** (`project_id`, for example `my-app`). Some use its **ID** instead (`projectID`, the 24-character `_id` returned when you create or list apps). Each endpoint says which one it expects. ## Deploying 1. Upload your source code as a `.tar.gz` or `.zip` archive with `POST /v2/projects/{project_id}/sources`. You get a `sourceID`. 2. Create a release with `POST /v2/projects/{project_id}/releases`, passing the `sourceID`. For `docker` apps you can pass a ready-made `image` instead. 3. Follow the build with `GET /v2/releases/{releaseID}/build-logs` and check the release `state` with `GET /v1/releases/{releaseID}` until it's `READY` (or `FAILED`, `CANCELED`, `TIMEDOUT` or `UNHEALTHY`). ## Interactive shell (WebSocket) Open a shell in a running app over WebSocket: ```text wss://api.liara.ir/v1/exec?token=&project_id=&cmd= ``` - `token`: your API token. - `project_id`: the app's name. - `cmd`: the command to run, for example `/bin/bash`. URL-encode it. - `teamID` (optional): the team that owns the app. You need the `operate` or `manage` permission on the app. Everything you send is passed to the command's input, and its output is sent back to you. If the app has never been deployed successfully, you get the message `Service does not exist yet. You should have at least one successful release.` and the connection closes. The handshake fails with `401` for a missing or invalid token, `400` if `project_id` or `cmd` is missing or `teamID` is invalid, `403` without access to the team or app, and `404` if the app doesn't exist. ## Team permissions With `teamID`, each endpoint needs one of the project permissions it lists (`view`, `deploy`, `operate` or `manage`). A permission from your role or a resource permission on that app both count. servers: - url: https://api.liara.ir security: - bearerAuth: [] tags: - name: Apps description: Create, list, inspect and delete apps. - name: Configuration description: Environment variables, port, DNS servers, plans and scaling. - name: Settings description: >- Read-only filesystem, default subdomain, zero-downtime deployment and fixed outbound IP. - name: Deployments description: Upload source code, create releases, follow builds and roll back. - name: Logs, Metrics & Events description: Runtime logs, resource usage and lifecycle events. - name: Networks description: Private networks that apps and databases are created in. paths: /v2/projects/{project_id}/logs/chart: get: tags: - Logs, Metrics & Events summary: Get log volume over time description: >- Returns how many log lines the app wrote in each 5-minute window.
