How to disable docker swarm mode?

Question

I have enabled docker swarm for local testing. Now, whenever trying to deploy using docker-compose up I see the following warning:

WARNING: The Docker Engine you're using is running in swarm mode.

Compose does not use swarm mode to deploy services to multiple nodes in a swarm. All containers will be scheduled on the current node.

To deploy your application across the swarm, use docker stack deploy.

How can I disable docker swarm mode?

Answer 1

docker swarm leave is used when you want a worker node to leave from swarm , while docker swarm leave --force is for a manager node to leave the swarm.

Answer 2

docker swarm leave should do the trick

Answer 3

If docker swarm leave and docker swarm leave --force do not working and return

 Error response from daemon: context deadline exceeded

you can remove /var/lib/docker/swarm and restart service.. for example in centos

systemctl restart docker

Answer 4

docker swarm leave --force

docker network prune

1st command to stop the swarm and then remove all the networks. This should work.
