Experimental Docker Support in Home Edition (64bit)




  • Joseph Honnoll

    I'm kinda new to Linux so what's the use of this feature?

  • Joseph Honnoll

    Thanks. Not a feature for me but for others yeah

  • Vince Pelss

    This looks like a very interesting.

    I think this is going to keep me busy for days!

    Forrest, it looks like when you guys added Flatpak and renamed the forum it broke your link above, the new link appears to be https://neverware.zendesk.com/hc/en-us/community/topics/360000017388-Flatpaks-Docker-VMs-etc

  • Forrest Smith

    Thanks dragon!

    I have recently replaced Mac OS Mojave on my 2015 MacBook Air with CloudReady and I'm determined to make the switch permanent!  One key item was the ability to spin up Docker containers, which this support article covers off on.  However, I also needed to have 'docker-compose' to spin up my development environment.

    After a lot of searching I found the solution that works and wanted to post the link/details here in case someone else was looking for a solution.

    The approach that worked for me was to Install Docker Compose as a Container.

    After following those steps, I was able to spin up my dev environment with one command.

    Hopefully this helps someone else out who may be looking.


    P.S. To the CloudReady team: THANKS FOR THE GREAT WORK! Crazy that Apple's native OS will not support more than 1 external display (only DP 1.1) even though the hardware supports DP 1.2. CloudReady allows me to have two external displays with an extended desktop. Thanks again!

  • Forrest Smith

    Thrilled to hear you're using Docker on CloudReady, and that it gives you more on the hardware that you have. That's why we make it so, cheers!

    Has anybody tried Onlyoffice-document-server as a docker? Possibly together with Nextcloud, or by itself? 

    I'd like Onlyoffice to try:

    1. Using onlyoffice in the browser. Whether connected or not.

    2. Using the logins to dropbox/box/webdav etc. witthout having to store the credentials online in personal.onlyoffice.com. 

    3. Possibly used in conjunction with a locally installed Onlyofice-desktopeditors to store encrypted externally? 

    Any other experiences? 





  • J. Muller

    Has anybody tried nextcloud or nextcloud+onlyoffice in docker on Cloudready-docker?

    I would be interested in:

    1.. Using access to a local nextcloud that can store in remote webdav/nextcloud/box/gdrive that is always encrypted. 

    2. Possibly using local onlyoffice with added blockchain encryption to remote as well.

    3. Running nextcloud apps like their epub-reader, dicom medical photoviewer etc.

    Last time I tried Docker was a few months back, and it had problems.

    I am happy to say I was able to run it successfully now on version 72.4.61.  I made a sample image, ran it and everything worked flawlessly.  I followed the initial learn/use documentation at Docker that Forrest had posted at the beginning of this thread.  Thank you!

  • Forrest Smith

    That's awesome!
    Thanks for the feedback Nero - appreciate you taking the time to let us know it got better.
    If you ever end up doing something interesting with docker on CR please share the details in a new post - I always want to lean more about how folks find that feature useful.

  • C. Nero

    One can create images fine.  But I cannot login to Docker to tag images or to push an image out there.  The problem is the read only file system.

    When using the docker login command (once you have created a login account at docker),

    the login succeeds (if the login had failed I will give another error msg), but then it fails when the credentials cannot be saved:

    Error saving credentials: mkdir /root/.docker: read-only file system

    Anybody knows a way to get around this?

  • C. Nero

    Another problem.   The stateful_partition is almost used up by docker.  How does one increase the size of the stateful_partition?  

    du -s  /mnt/*
    1866156 /mnt/stateful_partition
    localhost / # du -s  /mnt/stateful_partition/docker/
    825604  /mnt/stateful_partition/docker/

    docker is using up almost half of the stateful_partition.  I have created only about 200MB of images.

    At this point until docker login can be made to work, this no space is a moot problem.  

    Is there a way to delete the files and directories under docker that I created while playing with it.  Suggestions?


  • Forrest Smith

    You can remount as read write:

    sudo mount -o rw,remount /

    and it should prevent the first issue.


    As for the size of the stateful partition - if you install from USB to a disk, it'll expand to fill all available space, but on an installer USB the space is limited.

    As for deleting files and directories from Docker, I would guess that normal Docker commands/controls would do the trick.

  • C. Nero

    1. So far, I didn't have to compromise the security my the root rw.  I would prefer to keep it that way.  Hopefully the developers would eventually figure out how to store the credentials in some normal place like the rest of the applications do.


    2. Yes I am running from usb.  I do not have enough space on my windows lap top to install cloudready there.

    I will try the various docker commands.  So far removing most of the images I build did not reduce it.  But I will keep trying...

    Thanks for responding.

    There aren't really other applications - the browser is first-part built by Neverware and has special privileges, and there are virtually no other executables running outside the browser/browser's control besides Docker and Flatpaks. It's sort of an all-or-nothing security model, and Docker doesn't fit in perfectly at this point.

    You can alwasy make a new USB installer to start fresh if there's storage space loss building up over time. That'd be my backup-plan suggestion. 

  • C. Nero

    If I increase size of partition 16 by, say 2GB, will I get that increase in the stateful_partition space automatically?  Perhaps at the build?

  • C. Nero

    I think I can simply do,

       stop docker

       rm -rf /mnt/jstateful_partitiion/docker

    to remove all of docker's store.


       start docker

    all initial files are created there taking about 245MB.


  • Forrest Smith

    Glad you found a way to clear Docker's stateful content.


    I believe that if you can expand partition 16 then the OS will automatically recognize it as available.
