OS Drive almost full due to Docker

  • Hi there,


    Currently running Erasmus (3.0.71) off a 8gb usb stick beautifully.


    I have noticed over the last 3 weeks or so a steady reduction in disk space on the OS drive.
    I am running 2 docker containers (rutorrent and resilio) and I think that something in the containers folder is taking up more space (3.7gb of 8gb as below).


    I ran

    Code
    sudo du -hs /var/lib/docker/containers
    
    
    3.7G    /var/lib/docker/containers



    I'm really quite new to linux but my guess is it could be a log file. Is there an easy way to remove the log via the webui?
    I have tried looking in logs in the docker plugin in (on the webui) but omv crashes.


    Many thanks in advance


    Further investigation reveals it is the resilio-sync log file (about 3.7gb).


    I got some info from the redhat website


    Used the following to clear the contents of the log file (for the already running container)

    Code
    cat /dev/null > /var/lib/docker/containers/CONTAINER_ID/CONTAINER_ID-json.log

    I then have stopped and modified the docker container in the webui.


    I have read also that I can restrict the log file size using the following to 50mb


    Code
    --log-opt max-size=50m

    I have added it as an extra argument for the container. Will let you know if it works :)

  • Stumbled upon the same problem as of yesterday. I had recently installed resilio-sync via linuxserver.io docker container.


    For me /var/lib/docker/containers was taking more than 12G, due to the resilio one.


    I'm glad you found a solution, I will try to apply it on my setup.


    Off topic question, why resilio-sync and not syncthing? Is it because of the load syncthing is putting on the server (my reason to try resilio-sync)?


  • Let me know how you go.

  • Just want to say thank you for finding this and sharing it.


    I have 2 servers with 72GB SSD's for the OS's, and recently installed Resilio-Sync. The log files were over 68gb and maxed out my OS drives, not letting me access the webUI.


    I FTP'd in to the servers and found the large log files and deleted. After I saw they were creating 500mb log files withing an hour I found your post.


    just added this Argument to both docker containers and at 50mb they auto delete the log file and start over.


    Thanks!
