The bundle plan sets backups, metrics retention, editable settings and public network access. Moving to one that doesn't allow a feature you use fails. You can't move to a cheaper bundle plan soon after moving to a more expensive one. Team permission: `manage`. ## OpenAPI ````yaml /spec/dbaas.yaml post /v1/databases/{databaseID}/resize-bundle-plan openapi: 3.0.1 info: title: Databases version: 1.0.0 description: > Create managed databases, connect to them, change their plans and settings, back them up and restore them, and read their metrics and events. Supported types: `mysql`, `mariadb`, `postgres`, `mongodb`, `redis`, `mssql`, `elasticsearch`, `rabbitmq` and `clickhouse`. Databases are created in one of your private networks (see Networks in Apps & Deployments). ## Connecting `GET /v1/databases/{databaseID}` returns the connection details: - **From apps in the same network:** `hostname` and `internalPort`. - **Over the public network** (if `publicNetwork` is on): `network.node.host` and `port`. - **Credentials:** `username` and `root_password`. ## Team permissions With `teamID`, each endpoint needs one of the database permissions it lists (`view`, `operate` or `manage`). A permission from your role or a resource permission on that database both count. servers: - url: https://api.liara.ir security: - bearerAuth: [] tags: - name: Databases description: Create, list, inspect and delete databases. - name: Configuration description: Plans, scaling, settings, public network, password and control panel. - name: Backups description: Back up databases, download backups and import backup files. - name: Metrics & Events description: >- Resource usage, lifecycle events and the progress of background operations. paths: /v1/databases/{databaseID}/resize-bundle-plan: post: tags: - Configuration summary: Change the database's bundle plan description: >- Moves a running database to another bundle plan.
