The target disk's current contents are replaced. Team permission: `manage`. ## OpenAPI ````yaml /spec/paas-domains-disks.yaml post /v2/projects/{projectID}/disks/{name}/restore openapi: 3.0.1 info: title: Domains & Disks version: 1.0.0 description: | Connect custom domains to your apps and object storage buckets, and manage your apps' persistent disks, their backups and FTP access. ## Connecting a domain 1. Add the domain with `POST /v1/domains`. 2. Get its details with `GET /v1/domains/{domainName}` and create these DNS records at your DNS provider: - **Ownership:** a `TXT` record on `liara-challenge.` with the domain's `verificationCode`. You can skip it if the root domain is a zone managed in Liara DNS. - **Routing:** a `CNAME` record from the domain to its `target`. For a wildcard domain `*.example.com`, the check uses `__liara__.example.com`, which a wildcard record covers. - **Certificates through DNS validation** (needed for wildcard domains): a `CNAME` record from `_acme-challenge.` to `._acme-challenge.liara.cloud`, for example `_acme-challenge.example.com` → `example-com._acme-challenge.liara.cloud`. 3. Check the records with `GET /v1/domains/{domainID}/check`. The domain becomes `ACTIVE` once ownership is verified. 4. Request an SSL certificate with `POST /v1/domains/provision-ssl-certs`. ## Identifying an app Some disk endpoints identify the app by its **name** (`project_id`) and others by its **ID** (`projectID`, the app's `_id`). Each endpoint says which one it expects. ## Team permissions With `teamID`, each endpoint needs one of the permissions it lists on the app (or bucket) involved. A permission from your role or a resource permission on that app both count. servers: - url: https://api.liara.ir security: - bearerAuth: [] tags: - name: Domains description: Add, verify and remove custom domains. - name: Domain SSL & Redirects description: SSL certificates and redirects for custom domains. - name: Disks description: Create, resize and delete persistent disks. - name: Disk Backups description: Back up disks, download backups and restore them. - name: FTP Access description: FTP accounts for reading and writing disk files. paths: /v2/projects/{projectID}/disks/{name}/restore: post: tags: - Disk Backups summary: Restore a disk backup description: >- Restores one of a disk's backups onto a disk of the same app or of another of your apps.
