Docker GUI plugin now stable

  • can i update a running dockerimage?
    for examble i use emby and my docker image is older version. can i update the image and save the options from the old image?

    omv 6.x | 64 bit | omvextrasorg 6.x |
    used plugins: omv-extras | portainer | rsnapshot | antivirus
    used container: portainer/portainer | nextcloud/all-in-one | linuxserver/swag | paperless-ngx | jellyfin/jellyfin | lmscommunity/logitechmediaserver | adguard/adguardhome |

  • can i update the image and save the options from the old image?

    This depends entirely on the docker image you are using if it has the capability to mount folders into the container at startup to allow for persistent files. It also requires that you started your container with this kind of folder mapping. If the image has this support I would open the "copy" dialogue in the docker plugin and take screenshots of all parameters/variables that were used when the container was started. Next I would stop the running container, pull a new version of the docker image and fire up a new container with the same settings (except the name) as the old container and it should be all set. If everything is working as intended, remove the old container.


    However if there is no folder mapping support or it wasn't enabled at container creation there might be ways to get the configuration anyhow. Then I would start a shell inside the container via "docker exec -it <container_name> bash" Next depending on which underlying OS is used in the container I would install a ssh client/server and use scp to transfer any configuration files necessary (no idea which files that might be for emby since I don't use it) to the host OS. How to install ssh in the container varies on what is the underlying OS of the container so I'm afraid I can't help you out with that part.


    I hope this information will help you with upgrading your emby docker container without too much problems.

  • There is no such support in the plugin today. Personally I've made a similar setup as you want to achieve manually using the macvlan network driver. For those containers I'm not using the plugin... Additionally there is a docker openvpn image I'm using that relies on iptables to make sure all traffic on specific containers are forced via the vpn tunnel. Not sure if my setup really marches your requirements but let me know if you want more details.


    By the way, adding support for user specific networking is probably quite complex and not something I will be able to fix unfortunately. It is on the top of my own wishlist though :)


    Just to clarify, I'm not using macvlan with vlan trunking, but rather to give the containers their own layer2 access and providing them with their own IP numbers on the same network as my docker host. I have multiple vlans in my network but haven't had the need to isolate the containers on that level yet.

    Imo is not necessary to use vlan. You can use the internal current network and not having docker generate the iptables rules, with that you avoid masquerading, then you have to add a global static route in router to reach those containers. Then is easy to use the policy routing by ip at the firewall rules (pfsense) or in the load balancer (openwrt). youll also need probably to assign static ips to the container.


    If you want to configure containers with more network options you can try portainer which is a very good redo of dockerui

    Yes, I actully got around to doing this manually myself.. short hint for people who need this:


    Create the network (do not create the .30 interface! docker does this for you.)

    Code
    docker network create -d macvlan --subnet=10.0.10.0/24 --gateway 10.0.10.1 -o parent=eth0.30 vpnvlan


    Then just fire up dockers as you need, every container needs to have its own ip and there will be no need to exposing ports as all of the container ports gets exposed (exposing ports is also not supported by macvlan).



    Code
    docker run --name mydocker --net=vpnvlan --ip=10.0.10.2 .......


    Obviously this requires an trunked vlan 30 on eth0...

  • Hello,


    Using OMV and the Docker plugin for a few days now, very impressed. Thanks alot!


    I got one question: when I modify settings for a container, then the extra arguments are always gone, so I need to re-enter them. From what I've read in this thread, all settings of a container are taken from Docker, so no settings are stored in the plugin.
    So is this loss of extra arguments by design or a bug?


    Thanks for your help!

  • EDIT : I have been able to find a way around the problem.
    It is a problem with docker and my updated kernel (4.8) and aufs


    The simplest workaround is to do
    1) Install docker


    apt-get install docker-engine


    2) Try to see that docker doesn't start
    /usr/bin/dockerd




    3) Move one file from docker (for aufs) so docker won't complain about aufs
    mv /var/lib/docker/aufs /var/lib/docker/aufs_bk


    4) See that docker starts normally
    /usr/bin/dockerd


    Hello,


    I have tried to install the docker plugin( OMV 3) from the omv extra and it doesn't work.


    Can you please tell me what I have to do?



    Thank you

  • i found a side with options for a docker image.
    how do i push the options in?

    Code
    docker run -t -d -p 9980:9980 -e "domain=example.com" --cap-add MKNOD collabora/code

    i set the image in the GUI in host mode and whot i do with the other options?

  • Hello…


    Is it possible for the Docker to have an option to disable a Container? What we have now is STOP but it runs again after a restart or fresh boot up. it would be nice if there is a DISABLE/ENABLE feature

    • Offizieller Beitrag

    The restart policy is possible to modify without recreating the container. Unfortunately involves stopping docker engine service editing the Json configuration file and starting again docker engine. This means all containers are brought down for editing a specific policy of a specific container. Not viable for the plugin, but the modify button does a pretty close job to it.

  • Does the "modify" button works OK for all of you? For who answers... do you use OMV in port 80/443 or custom port?


    When I try to save the "Modify" form, it brings me an error: "Error: "Failed to connect to localhost port 80: Connection refused" - Code: 7"

  • Modify doesn't work for me also, something goes wrong I think
    but error is different

  • Is the docker plugin working under 3.0.63? I am running a fresh install with kernel: 4.9.0-0.bpo.1-amd64.
    Currently I am having an issue with just initializing the plugin. If I initialize it theres tons of errors that keep telling me to apply changes or revert. If I apply more of the same errors occurs.


    So I am seeing if this is just an issue with erasmus being beta still. Also its weird that some of the errors will say that I don't have a filesystem in place but I browsed to get the location I used.


    Thanks

    I had something related and it was caused because of storage driver in Docker configuration. Try using others. I had aufs and now in newer kernels only overlayfs works for me.

    • Offizieller Beitrag

    aufs is not available in any of the Debian 4.x kernels.

    Please try ctrl-shift-R and read this before posting a question.

    Please put your OMV system details in your signature.
    Please don't PM for support... Too many PMs!

  • so here is what happens if I enable the plugin and set location of docker base path (I just set it to my storage partition)





    then after I click ok on that if I hit apply configuration changes I get the following error.


    this is the error about filesystem not existing.
    Any help would be awesome.
    Again this is a fresh install of OMV 3.


    Thanks.
