How to update docker stack without restarting all services
Redeploying the stack with changed configuration(docker-compose.yml file) solves the problem see https://docs.docker.com/engine/reference/commandline/stack_deploy/#extended-description.There they stated "Create and update a stack from a compose or a dab file on the swarm." Also i dont see any command like 'docker stack update'. So this can solve the problem.
