Clear container logs¶

To clear the logs of a container your can:

echo "" > $(docker inspect --format='{{.LogPath}}' <container_name_or_id>)

if the container is not running. Otherwise, you can configure docker to limit the size of the logs as explained in stackoverflow.

Start the manager:

docker swarm init

Connect the workers with the command provided by:

docker swarm join-token worker

Create an overlay network:

docker network create --driver overlay mynet

Start deploying your services or stacks:

docker stack deploy -c mystack.yml mystack

Remove unused files:

docker system prune

Leave swarm and remove the temp directory:

docker swarm leave
systemctl stop docker
# recommended to also rm the node from the swarm
rm -rf /tmp/docker/*
systemctl stop docker
# rejoin swarm

In the master node, the folder /var/lib/docker might also contain data that can be deleted.
