Authorizations

​
Authorization
string
header
required

API key for authentication. Make sure to include the word apikey, followed by a single space and then your token. Example: apikey 1234$abcdef

Path Parameters

​
project_id
integer
required

Project ID

Example:

1

​
region_id
integer
required

Region ID

Example:

7

​
cluster_id
string<uuid4>
required

Cluster unique identifier

Example:

"1aaaab48-10d0-46d9-80cc-85209284ceb4"

Body

application/json
​
image_id
string<uuid4>

Image ID of the OS image to apply to the cluster template. Use GET /v1/images/{project_id}/{region_id} to discover available images. Takes effect on existing servers only after a successful POST /apply_settings call.

Example:

"3793c250-0b3b-4678-bab3-e11afbc29657"

​
name
string

Cluster name

Maximum string length: 63
Pattern: ^[a-zA-Z0-9][a-zA-Z 0-9._\-]{1,61}[a-zA-Z0-9._]$
Example:

"gpu-cluster-1"

​
servers_settings
PatchServerSettingsInputSerializer · object

Configuration settings for the servers in the cluster

Example:
{
  "credentials": { "ssh_key_name": "my-key" },
  "user_data": "eyJ0ZXN0IjogImRhdGEifQ=="
}
​
tags
UpdateTagsSerializer · object

Update key-value tags using JSON Merge Patch semantics (RFC 7386). Provide key-value pairs to add or update tags. Set tag values to null to remove tags. Unspecified tags remain unchanged. Read-only tags are always preserved and cannot be modified.

Examples:

  • Add/update tags: {'tags': {'environment': 'production', 'team': 'backend'}} adds new tags or updates existing ones.
  • Delete tags: {'tags': {'old_tag': null}} removes specific tags.
  • Remove all tags: {'tags': null} removes all user-managed tags (read-only tags are preserved).
  • Partial update: {'tags': {'environment': 'staging'}} only updates specified tags.
  • Mixed operations: {'tags': {'environment': 'production', 'cost_center': 'engineering', 'deprecated_tag': null}} adds/updates 'environment' and 'cost_center' while removing 'deprecated_tag', preserving other existing tags.
  • Replace all: first delete existing tags with null values, then add new ones in the same request.
Example:
{
  "my-tag": "my-tag-value",
  "my-tag-to-remove": null
}

tags
TagSerializer · object[]
required

List of key-value tags associated with the resource. A tag is a key-value pair that can be associated with a resource, enabling efficient filtering and grouping for better organization and management. Some tags are read-only and cannot be modified by the user. Tags are also integrated with cost reports, allowing cost data to be filtered based on tag keys or values.

Example:
[
  {
    "key": "my-tag",
    "read_only": false,
    "value": "my-tag-value"
  }
]
​
