Docker-Compose Restart Policy
I looked thru the docs for docker-compose and I see that Version 3 has a deploy restart policy but it’s only for swarm. I tried setting restart_policy on my service but got this error:
ERROR: The Compose file './docker-compose.yml' is invalid because: Unsupported config option for services.web: 'restart_policy'
Is there any way to set a restart policy on services created using docker-compose outside of a swarm?

Version 2 supports restart policies, using the
restart keyword, and should work fine for you if you don’t need Swarm (which you said you don’t need/want).
version: '2' services: web: image: apache restart: always
Compose format version 3 has a parameter called
restart_policy, but so far as I can tell from documentation it is only valid as part of
deploy, which is only used when deploying to a Swarm. So version 3 is probably not useful in your case.
It’s looks like a gap in documentation
In 3rd version we can still use “restart” inside services same as before in v.2 (except for deploy into swarm)
version: '3' services: my-service: restart: on-failure:5
