Security group rules

Maximum array length: 250
​
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
}
