## What

Docker/SSH outpost service-connection fails because the SSH key/config is missing or unused on the worker (including K8s multi-replica).

## Want

- Docker/SSH outpost service-connection fails because the SSH key/config is missing or unused on the worker (including K8s multi-replica)

Start at the authentik.outposts.tasks.outpostcontroller task mentioned in the related Kubernetes issue and reproduce the Docker/SSH service-connection failure with multiple worker replicas. Compare the related issues #3679, #4314, and #22968 to trace how the worker receives SSH key/configuration. Done means the connection succeeds reliably, including in a Kubernetes multi-replica deployment.
