Open Stack


Hello Vincent,

To allow a user from a container to access files on OpenStack, you can use the --volume or -v option when creating the container to mount a host file or directory as a volume inside the container. For example:

Copy code
docker run -it --volume /path/on/host:/path/in/container image_name

This will mount the host file or directory located at /path/on/host as a volume inside the container at /path/in/container. The user inside the container will be able to access the files in the volume at /path/in/container.

You can also use the --mount option to mount a volume. This option provides more control over the volume, such as specifying the volume driver and options. For example:

Copy code
docker run -it --mount type=bind,source=/path/on/host,target=/path/in/container image_name

This will also mount the host file or directory located at /path/on/host as a volume inside the container at /path/in/container, and the user inside the container will be able to access the files in the volume at /path/in/container.

Note that the /path/on/host must be an absolute path and must exist on the host system. The /path/in/container can be any path inside the container and does not need to exist prior to the mount.

It's also important to note that the user inside the container must have the appropriate permissions to access the mounted files. You can use the --user option to specify the user that the container should run as, or you can set the ownership and permissions of the mounted files on the host system to allow the user inside the container to access them.

Hope it works for you..
