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?

Swarm mode orchestration has the objective to make the current state match your target definition. So "stop all the containers" brings your current state out of the target state goal and swarm will try to correct that. You could do this by changing your target, but that needs to be done per service.
To add a worker to this swarm, run the following command: docker swarm join \ --token SWMTKN-1-49nj1cmql0jkz5s954yi3oex3nedyz0fb0xx14ie39trti4wxv-8vxv8rssmk743ojnwacrr2e7c \ 192.168. 99.100:2377 To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.
The safe way to remove a manager from a swarm is to demote it to a worker and then direct it to leave the quorum without using --force . Only use --force in situations where the swarm will no longer be used after the manager leaves, such as in a single-node swarm.
Docker Engine 1.12 introduces swarm mode that enables you to create a cluster of one or more Docker Engines called a swarm. A swarm consists of one or more nodes: physical or virtual machines running Docker Engine 1.12 or later in swarm mode. There are two types of nodes: managers and workers.

To remove worker2, issue the following command from worker2 itself: $ docker swarm leave Node left the default swarm. The node will still appear in the node list, and marked as down. It no longer affects swarm operation, but a long list of down nodes can clutter the node list. To remove an inactive node from the list, use the node rm command.
And in any case, when stopping a container, Swarm mode automatically starts another container, with a different hash at the end of container name.
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? 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.

docker swarm leave should do the trick
