runner.group-set-container-image ​
Set runner_group.config.container_image and, for ECS-backed groups, re-register the task definition so the next launch picks up the image.
One-shot 'change the image' verb — config write + task-def re-register.
Overview ​
| Property | Value |
|---|---|
| Workflow type | Linear |
| Library | App-runners |
| Version | 1.0 |
Input Schema ​
| Field | Type | Required | Default | Description |
|---|---|---|---|---|
runner_group_uuid | uuid | Yes | — | UUID of the RunnerGroup this action operates on, picked from the organization's list of runner groups. |
organization_uuid | uuid | Yes | — | UUID of the caller's organization, injected server-side from the authenticated request; scopes the operation to the correct tenant. |
container_image | string | Yes | — | Fully-qualified image reference, e.g. ghcr.io/ltinteg/ltinteg-agent-runner:latest. When the runner group has registry_account_uuid set, this MUST be a plain repo:tag (no registry host) — the platform prepends the account's registry endpoint. |
