NAME
podman-cp - Copy files/folders between a container and the local filesystem
Description
We chose not to implement the cp feature in podman even though the upstream Docker
project has it. 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.
