In my case, I found that–for whatever reason–there was one docker container with a “Dead” Status. Removing that “Dead” container followed by a ./launcher start app worked!
Note that I also found that restarting the docker service and even restarting the server did not resolve this issue. Only the following did:
First let’s get a list of all the docker containers. This is a staging box I’m using for a Discourse POC for our org, and it appears to have accumulated a ton of Discourse-related containers. One stands out with a Status = “Dead”
