Cleaning up Dockers

I prefer

docker system prune --volumes

see my experience: [HOWTO] free / prune space used by dockers

If you use watchtower, you can also tell watchtower to cleanup

add an env variable:

WATCHTOWER_CLEANUP=true

Here the docker-compose file to run in Portainer or from CLI

Code

version: "2"
services:
  watchtower:
    container_name: watchtower
    image: containrrr/watchtower
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    environment:
      - WATCHTOWER_CLEANUP=true
      - WATCHTOWER_POLL_INTERVAL=86400 #check for updates once per day
    restart: unless-stopped

An update to the guide here another option to get information on used Docker space is to run;

docker system df this will give you information on 'Reclaimable' space

docker system prune -a as per the guide this will remove unused images, stopped containers and clean up your Docker install, another option is to run;

docker image prune -a this will remove all unused images, and any images with stopped containers

docker container prune -a this will remove all stopped containers.

That helped me and saved a lot of time. Thank you so much.

Hello,

I encouter the same problem with the GUI OMV interface coming again after logging.

I followed the guide identifying the deepest folder taking place and then ran the command docker system prune --volumes

Something happened in term of place but I still get the same error and am not able to log into the GUI interface.

Best regards,

Harold

Thank's for tips

I use the labels to update only the constianers I want.

WATCHTOWER_LABEL_ENABLE    true
WATCHTOWER_SCHEDULE    0 0 0 * * 0

in the container
labels:
      com.centurylinklabs.watchtower.enable: true
