delete-stalled-concourse-worker
In certain situations its possible for workers to stay in a stalled state. This application can be run to prune those workers.
GKE use case
At Brandwatch we run Concourse on Kubernetes (GKE) using preemptbile VMs. When VMs are preempted we are left with stalled workers, and so run this as a cronjob every minute to clean them up.
