Why Docker Swarm services restart and stop indefinitely?

Question

Docker

For no apparent reason or error, services in a Docker Swarm cluster stop and are re-created without stopping.
Services have flags restart on-failure

What could be the problem? I've looked all over and can't figure it out.

Answer 1

You need to look at the statuses with which the tasks fell off
docker stack ps <stack_name> --no-trunc
