We have a much stronger capability. Using standard podman-mount +and podman-umount, we can take advantage of the entire linux tool chain, rather +then just cp. + +If a user wants to copy contents out of a container or into a container, they +can execute a few simple commands. + +You can copy from the container's file system to the local machine or the +reverse, from the local filesystem to the container. + +If you want to copy the /etc/foobar directory out of a container and onto /tmp +on the host, you could execute the following commands: + + mnt=$(podman mount CONTAINERID) + cp -R ${mnt}/etc/foobar /tmp + podman umount CONTAINERID + +If you want to untar a tar ball into a container, you can execute these commands: + + mnt=$(podman mount CONTAINERID) + tar xf content.tgz -C ${mnt} + podman umount CONTAINERID + +One last example, if you want to install a package into a container that +does not have dnf installed, you could execute something like: + + mnt=$(podman mount CONTAINERID) + dnf install --installroot=${mnt} httpd + chroot ${mnt} rm -rf /var/log/dnf /var/cache/dnf + podman umount CONTAINERID + +This shows that using `podman mount` and `podman umount` you can use all of the +standard linux tools for moving files into and out of containers, not just +the cp command. + +## SEE ALSO +podman(1), podman-mount(1), podman-umount(1) |
