Pull an image onto a node

POST /v1/admin/runtime/nodes/{id}/pull-image

• Operation ID: pullRuntimeNodeImage
• Tags: Runtime pools and nodes
• Base URL: http://localhost:8787

Asks the node agent to pull a container image. Audited as runtime.node_pull_image. Authenticates with a Platform staff JWT and permission, like every admin route; the backend calls the separate Runtime service on the caller's behalf (no Runtime API key is ever exposed or accepted).

Workflow: Integration guide.

Authentication: staff Bearer JWT with permission runtime.write.

Authentication

• Auth: staff Bearer JWT (Authorization: Bearer <access_token>) with the permissions below.
• Required permissions: runtime.write
