runner.update_task_definition ​

Update runner ECS task definition

Register a fresh task definition revision for environment updates.

Also upserts the Secrets Manager pull-secret when the runner group has a registry_account_id configured, so that refreshing an existing group retroactively enables cross-cloud image pulling without a full reprovision.

Input Schema ​

FieldTypeRequiredDefaultDescription
runner_group_uuiduuidYes—UUID of the RunnerGroup this action operates on, picked from the organization's list of runner groups.
organization_uuiduuidNo—UUID of the caller's organization, injected server-side from the authenticated request; scopes the operation to the correct tenant.
workflow_run_idstringNo——
workflow_run_uuidstringNo—Internal engine correlation/run identifier for this DAG execution (ADR-015/E1 plumbing), not a foreign key to any business entity. No list/query workflow applies.

Output Schema ​

FieldTypeRequiredDefaultDescription
runner_group_uuiduuidNo—UUID of the RunnerGroup this workflow operates on, picked from the organization's list of runner groups. Optional on this shared passthrough schema because the same field also appears as an output-only echo.
organization_uuiduuidNo—UUID of the caller's organization, injected server-side from the authenticated request; scopes the operation to the correct tenant.
registry_account_uuiduuidNo—UUID of the container registry account this runner group resolves images against, picked from the organization's registry accounts. Optional — falls back to default/unauthenticated image resolution when absent.
actor_uuiduuidNo—UUID of the user or service actor who triggered this action, injected server-side from the authenticated request when available; used for audit/attribution only.
workflow_run_idstringNo——
workflow_run_uuidstringNo—Legacy alias of workflow_run_id: an internal engine correlation/run identifier for this DAG execution (ADR-015/E1 plumbing), not a foreign key to any business entity. No list/query workflow applies — this is engine-generated, never user-supplied.
workflow_uuidstringNo—Engine workflow-run identifier associated with this record; not a platform entity foreign key despite the name. No list/query workflow applies — this is engine-generated, never user-supplied.
