How was dokku installed?:
From the DO droplet on-click gallery. Dont know have the image was composed.

How reproducible:
In my case the app was deploying fine untill I added a DOKKU_SCALE file to scale a worker to 1 instance. Then deploys started failing immediately.

Steps to Reproduce:
1. Add DOKKU_SCALE file to root of rails app
2. Deploy
3. See error :-).

Actual Results:
remote: Error response from daemon: Cannot kill container 483221d17cc9e401e8397f23d994065b0807434b3d62746de3f9218ba0722073: notrunning: Container 483221d17cc9e401e8397f23d994065b0807434b3d62746de3f9218ba0722073 is not running

Expected Results:
A successful deploy
