Changing docker startup options without re-creating container

With command line

If the container is running and you want to modify it’s settings:

docker update --restart=<policy> <name>

If the container is not running and you want to start it:

docker container run --restart=<policy> <name>

Policy can be any of those:

• no
• always
• unless-stopped
• on-failure

With docker-compose

It can be set in docker-compose file like that:

version: "3"
services:
  app:
    image: linkace/linkace:simple
    restart: unless-stopped
