docker mount windows share

you are getting and the fin sysinfo output. As you can see, I'm not asking out of the blue and have invested tons of time researching and testing. This fails as when I try to create the container including tyhe above string, I get the error: > /usr/bin/docker-current: Error response from daemon: error setting label on mount source /share/files: SELinux relabeling of /share/files is not allowed: operation not supported. https://hub.docker.com/r/alinmear/docker-conanexiles/, https://hub.docker.com/r/alinmear/docker-conanexiles/dockerfile, Attempt 1: Mounting Share to Host using CIFS then Attaching Mounted Folder as Volume to Container, Attempt 2: Mounting Share to Host using CIFS then Attaching Mounted Folder as Volume to Container Excluding SysLinux Parameters, Attempt 3: Using the NetShare Docker Plugin, Attempt 4: Mounting Share Inside of Container Using CIFS, Deleting the container & its volumes then adding new, Updating apt-get then installing cifs-utils, Creating /.smbcredentials with credentials (obviously), Removed the pre-existing commented line of "# UNCONFIGURED FSTAB FOR BASE SYSTEM", Added the string "//myserver/files$ /filestest cifs iocharset=utf8,credentials=/.smbcredentials,file_mode=0777,dir_mode=0777,context="system_u:object_r:container_file_t:s0" 0 0", Also tried "chmod 0777 /files" then "mount -a" again. Finally, as you know; my main concern was the ability for a few containers to have full access to Windows shares. or if you accidentally replied No, then the adapter fail to set up properly and Call mount -a, Windows share is here and accessible. SElinux is the only protection your file system has against container breakout, so disabling it makes you system a lot more at risk. What potential ramifications may this have on my other containers? The text was updated successfully, but these errors were encountered: I believe this is SELinux blocking the access. The container I plan to initially test this on was already added with the parameter "--cap-add SYS_ADMIN --cap-add DAC_READ_SEARCH ". might fail to work. Those elevated prompts are sometimes appear minimized on the taskbar. It is now read-only. man mount.cifs), I got the above error again. We had cases when Check your password. You would need to refer to the same When attempting to use it by executing "docker volume create -d cifs --name myserver/files$" (which is a valid shared path), I got the error: Error response from daemon: create myserver/files$: create myserver/files$: Error looking up volume plugin cifs: legacy plugin: plugin not found. If I connect to the container, I can cd into /files, however simply trying to execute "ls" fails with the error: ls: cannot open directory '. Any suggestions you have would be greatly appreciated. So thats where Im at. GOing to try adding "--privileged" Thanks. Do not proceed to next steps if you have not fixed the issue If you see the shares but can not access them, then most likely you hit some edge case. ': Permission denied. If you have questions on resolving issues with steps above, try searching the issue queue or most common reason is Windows Firewall blocking it. Other special symbols are not an issue, but in case your password contains some other special Current workaround would be to run the container with privileged mode(Not secure), Powered by Discourse, best viewed with JavaScript enabled, Best Solution to Mount a Windows Share within a Container, How to share Docker volumes across hosts - JAXenter, Updated apt-get then installed nano & cifs-utils, Created the file /.smbcredentials with credentials inside of it then ran chmod against it, Created a new folder in the root named /filestest and set it to 0777 with chmod, Edited /etc/fstab and added the below string. Where it says: does that mean I have to create the /conanexiles folder somewhere? Im using the exact same mount command that succeeds inside the same container, but when the host is an ubuntu machine. Check for Windows Network Settings Issues, elaborate post on superuser about issues with File/Printer sharing on Windows, Microsoft account should use Microsoft account password, not the one that is used to unlock PC. In worst case try removing Docksal VM with fin vm remove, uninstall VirtualBox, reboot, install Enable it in network settings and I have followed your examples and I'm nearly there but I'm just having a problem telling it to mount the volume. I need to better understand how the networking with the container works, but Im not sure its the networking thats at fault. This repository has been archived by the owner. This means the problems could have to do with your Fedora setup. You could copy the /etc/fstab as part of your docker build process. Check that you can create shares, but do not create Docksal shares manually (If error with vm I've posted everywhere about this and you are the only one who's helped at all. VirtualBox and start vm again. I had to run the container in privileged mode in rancher to get this to work. re-installing Windows. You signed in with another tab or window. then create an issue on GitHub (see step 6), so we could investigate and fix. If I can get it working, I'll be golden. So for the "--context="system_u:object_r:container_file_t:s0"" parameter you mentioned above, where would you propose it be tested? Disable SELinux I haven't heard of SilverBlue, but will check it out first. I ran across containx/docker-volume-netshare which is a Docker plugin that supposedly allows easier mounting of shares with containers so thought i'd try it out. What is the suggested method for mounting a Windows Share to a container so that the container has full Read/Write access to the files/folders within? I would put it in the fstab with something like this: /myserver/files$ /filestest cifs iocharset=utf8,credentials=/.smbcredentials,file_mode=0777,dir_mode=0777,context="system_u:object_r:container_file_t:s0" 0 0, Ha - apologies and actually glad you brought it up as I although somewhat new to "container technology" :), I don't want to sound like an idiot. That is why I as suggesting that you mount the share with the label I suggested, Then you could just run containers off of the volume. Ive tried this on Debian with a Debian container and mounted a share of my Windows PC, following your description. This is the IP that VirtualBox adapter assigns to your host machine. When connecting to the container after creation, I found that it did create /filestest yet I got the same error when trying to list files within it. The The issue is that I have a couple of other containers which I want to mount Windows shares, but they do not have apt-get or yum and seemingly rely on pip for installations which to my knowledge cannot install cifs-utils. If share creation fails, Docker will not be able to access your files. start is not related to mounting or shares, then see regular troubleshooting guide.). So you are actually executing the mount from within the container? Docksal can not fix it for you, because there are dozens of reasons why it Update 2 There are many additional things that I want to do with it, however continue to hit a single roadblock. If there is no shares but IP opens While in the docker container on the windows host, I can successfully ping the host that has the CIFS folder 192.168.1.12 in my case, but I cant mount the CIFS folder (//192.168.1.12/something) from that host. Do you think that the default network settings (bridge) can exhibit such behavior? docksal-c, docksal-d etc. Ive done a ton of research and testing without finding a solution so far so wanted to make an all-inclusive post. I first added the string below when building a typical container as the posts said it was required: cap-add SYS_ADMIN --cap-add DAC_READ_SEARCH \. It also seems to be able to update the game from within the container indicating that it has internet access through some invisible medium; I just don't know how to directly interact with the files inside this container or if even I should. When mounting the share to the host (1st options above) or at the end of the string within /etc/fstab (last option above) thus yielding something like the below: //myserver/files$ /filestest cifs iocharset=utf8,credentials=/.smbcredentials,file_mode=0777,dir_mode=0777 0 0 --context="system_u:object_r:container_file_t:s0". The part about volumes is what I am not too sure of. As for disabling SELinux, most of my containers do have volume mounts, but all were initially made with ":z" as I found early on that I had to use it in order for many of them to have read/write access to the mounted paths. Or is that file how to create the docker container (beyond my skills at the moment). Try running fin vm restart. Discussions on GitHub. Only one issue remaining if you don't mind. This will only happen if there is no configuration already existing (the case of a clean container initialization). Make sure that you see and can In the container ls /usr/src/app, everything is here, touch a file somewhere in these folders, it appears in the Windows Explorer. If there is a folder with configurations found at /tmp/docker-conanexiles this folder will be copied to the config folder of the server. When I start the container with docker-compose up from within the correct folder on the linux server the container appears to run referencing file paths and it seems to log events as a normal dedicated server should. Any suggestions you have would be greatly appreciated. You can also contribute changes to this page using the link in the top right corner. Ive tried installing its DEB which I seemingly cannot do with Atomic, installing it using rpm-tree (Atomic doesnt have yum/apt-get), trying to install it using docker plugin install containx/docker-volume-netshare, building it from source, and finally just copying and running its binary. If you get errors when trying to open it, then there is an issue with VirtualBox network adapter. Being very new to docker how would you go about this? If both IPs are working, then its not the network access issue. So in principle everything works. Pay attention to them and reply Yes. //143.1.1.1/data\\040import /mnt/import cifs rw,credentials=/etc/smbcredentials,uid=1000,gid=1000,file_mode=0777,dir_mode=0777 0 0, docker run --cap-add SYS_ADMIN --cap-add DAC_READ_SEARCH testbuild. Refer to the mount.cifs(8) manual page (e.g. I am in the process of building an image with the code included and I would like to automate the mounting of the windows share but I can't get it to work in the dockerfile and I don't see any way to mount it as a volume to the container in rancher. CIFS mounts are a bit tricky and error messages not always helpful. In this step you need to check access to Docksal IP. if you are stuck, you can also create an issue on GitHUb to ask a question. I've read a lot about it being bad practice to do this. A section for each is below with detail and results. Mounted my Windows PC to /home/tekki/mypc, then. I would look at replacing docker commands with podman where ever possible, ALso suggest running some of your containers as non root using podman. Can I check if you have to run the container as privileged? worked like a charm. If you have existing containers running with volume mounts, you might need to do some relabeling. Is the password correct? CIFS Parameters --security-opt label=disabled. And whats this Dollar sign in fstab? When creating the container I wish to access it, I add a volume by including the below string: -v /share/files:/files:z \ (Added :z since use Atomic with SysLinux). If the issue with share creation does not go away and you think Would you mind elaborating a bit? 2. In that case, Docker also will not be able to access your files. My docker image is ubuntu based so maybe Ill have more luck with the NetShare plugin. Once done, I followed the same steps above and the share mounted successfully as I was able to create a new file in the share using vi. I've tried installing it's DEB which I seemingly cannot do with Atomic, installing it using rpm-tree (Atomic doesn't have yum/apt-get), trying to install it using "docker plugin install containx/docker-volume-netshare", building it from source, and finally just copying and running it's binary. The closest I got was by downloading and testing the binary as after setting its permissions, I could execute "docker-volume-netshare -h" and see the help and other notes. This is the same as the above test, but I remove ":z" from the end of the string resulting in: I am able to create the container successfully, however; cannot access the files. it not password or policies, then see step 6. access shares that Docksal should have created for your local drives. To load my windows share inside my Docker volume permanently, this is what worked for me: Windows Share= //192.xxx.xx.xx/windows_share/ Docker Volume: volume=/docker_volume username=""/password="" added to file /etc/smbcredentials. Provide a Config Given my post, would it make more sense / be easier to manage something other than Atomic Fedora? That is an unusual practice, the standard is to mount the shares on the host, and then volume mount them into the container. try opening that IP again. Open explorer and navigate to \\192.168.64.1\. Sharing data between Docker containers across different hosts is a tricky business. You checked out the first step and there seems to be no If you dont see those shares altogether, then there is an issue with shares creation. symbols and you see errors that contain Invalid argument: In this case, try simplifying your password. You could either disable SELinux within docker (Although I would prefer you to play with podman), Or mount your cifs share with --context="system_u:object_r:container_file_t:s0". Do you think Atomic CentOS make any different regarding the above issue or perhaps something like CoreOS, UNRAID, RancherOS, or even a full Linux OS? I think that did it. So far, I've tried the below methods without success. A section for each is below with detail and results Basically, I use CIFS to mount the Windows share with 0777 to an empty path on the host like /shares/files. I run Docker via Atomic (Fedora 29) on a dedicated system which I've used for a few months now and absolutely love it. Everything works as expected. Thanks for the feedback. The closest I got was by downloading and testing the binary as after setting its permissions, I could execute "docker-volume-netshare -h" and see the help and other notes. Press J to jump to the feed. Ubuntu has different packages, but the method is the same: Your image needs this, however you want: dnf -y install autofs samba-client samba-common, //artoo/video /mnt/video cifs soft,credentials=/etc/smbcred.txt,uid=1000,gid=1000 0 0, username=myusername password=mypassword domain=mydomain. Note: I tested mounting to a folder which pre-exists in the container as well as defining a new one when creating the container. This all being said, since the last update of Conan Exiles I haven't had much luck with a server I know to have been working prior to the update so I am a little unsure if it's funcom needing to fix something or my lack of skill and understanding of all things docker. We are using rancher to manage everything so I don't seem to have the ability to use docker-compose, I've solved the problem by adding this to the dockerfile, CMD ["sh","-c","mount -a && pm2-runtime app.js"]. issue on GitHub and we will investigate the edge case. I should note that I was able to mount the CIFS shared folder inside the docker image, when the host was Ubuntu, but not when the host was Windows. fix is to stop Docksal VM, remove those shares manually using Windows UI and start VM back again. I had assumed this would be a pretty easy thing to do but I've been at it for hours now and I can't get it working. My Docker host is a dedicated system for Docker containers for my home lab's use. Really appreciate the reply - thanks! This is my workflow to successfully mount a share from 192.168.1.110 into a container running on another Windows machine: Add username and password, save. Also, how does this https://hub.docker.com/r/alinmear/docker-conanexiles/dockerfile relate to the container? I posted an issue in their GitHub repo and tried a variety of other things, but didnt get a response after weeks and had no further luck. I found a couple of posts suggesting this could work, so gave it a shot. Open an issue Update I cringe when i see the Docker word so often. I found a couple of posts suggesting this could work, so gave it a shot. Also, the host is in my home lab where I am the only local user. people had mysterious issues related to shares mounting. man mount.cifs). I'll give podman a shot assuming it is supported on the container host OS I choose plus add all containers as non-root unless I cannot get it to work otherwise. Thanks again as I really appreciate your reply! When attempting to use it by executing "docker volume create -d cifs --name myserver/files$" (which is a valid shared path), I got the error: Error response from daemon: create myserver/files$: create myserver/files$: Error looking up volume plugin cifs: legacy plugin: plugin not found. your only option would be to remove vm with fin vm remove and start it again. and then connect to it with an interactive bash the volume isn't mounted but mount -a works so I'm assuming I just need to ammend the run command to tell it to mount this volume I have already configured?
