            QUESTION

            A working how-to for data extraction of non-root named volume permissions working with linux and win
            Asked 2018-Oct-10 at 16:38

            I'm trying a simple workflow without success and it take me a loooooot of time to test many solutions on SO and github. Permission for named folder and more generaly permissions volume in docker is a nightmare link1 link2 imho.

            So i restart from scratch, trying to create a simple proof of concept for my use case.

            I want this general workflow :

            • user on windows and/or linux build the Dockerfile
            • user run the container (if possible not as root)
            • the container launch a crontab which run a script writing in the data volume each minute
            • users (on linux or windows) get the results from the data volume (not root) because permissions are correctly mapped

            I use supercronic because it runs crontab in container without root permission.

            The Dockerfile :

            ...

            Let me divide the answer into two parts Linux Part and Docker part. You need to understand both in order to solve this problem.

            Linux Part

            It is easy to run cronjobs as user other than root in Linux.

            This can be achieved by creating a user in docker container with the same UID as of that in the host machine and copying the crontab file as /var/spool/cron/crontabs/user_name.

            From man crontab

            crontab is the program used to install, deinstall or list the tables used to drive the cron(8) daemon in Vixie Cron. Each user can have their own crontab, and though these are files in /var/spool/cron/crontabs, they are not intended to be edited directly.

            Since Linux identifies users by User Id, inside docker the UID will be bound to the newly created user whereas in host machine the same will be binded with host user.

            So, You don't have any permission issue as the files is owned by the host_user. Now you would have understood why I mentioned creating user with same UID as of that in host machine.

            Docker Part

            Docker considers all the directories(or layers) to be UNION FILE SYSTEM. Whenever you build an image each instruction creates a layer and the layer is marked as read-only. This is the reason Docker containers doesn't persist data. So you have to explicitly tell docker that some directories need to persist data by using VOLUME keyword.

            You can run containers without mentioning volume explicitly. If you do so, docker daemon considers them to be UFS and resets the permissions. In order to preserve the changes to a file/directory including ownership. The respective file should be declared as Volume in Dockerfile.

            From UNION FILE SYSTEM

            Indeed, when a container has booted, it is moved into memory, and the boot filesystem is unmounted to free up the RAM used by the initrd disk image. So far this looks pretty much like a typical Linux virtualization stack. Indeed, Docker next layers a root filesystem, rootfs, on top of the boot filesystem. This rootfs can be one or more operating systems (e.g., a Debian or Ubuntu filesystem). Docker calls each of these filesystems images. Images can be layered on top of one another. The image below is called the parent image and you can traverse each layer until you reach the bottom of the image stack where the final image is called the base image. Finally, when a container is launched from an image, Docker mounts a read-write filesystem on top of any layers below. This is where whatever processes we want our Docker container to run will execute. When Docker first starts a container, the initial read-write layer is empty. As changes occur, they are applied to this layer; for example, if you want to change a file, then that file will be copied from the read-only layer below into the read-write layer. The read-only version of the file will still exist but is now hidden underneath the copy.

            Example:

            Let us assume that we have a user called host_user. The UID of host_user is 1000. Now we are going to create a user called docker_user in Docker container. So I'll assign him UID as 1000. Now whatever files that are owned by docker_user in Docker container is also owned by host_user if those files are accessible by host_user from host(i.e through volumes).

            Now you can share the binded directory with others without any permission issues. You can even give 777 permission on the corresponding directory which allows others to edit the data. Else, You can leave 755 permissions which allows others to copy but only the owner to edit the data.

            I've declared the directory to persist changes as a volume. This preserves all changes. Be careful as once you declare a directory as volume further changes made to that directory while building the will be ignored as those changes will be in separate layers. Hence do all your changes in the directory and then declare it as volume.

            Here is the Docker file.
