Copying files in and out of a container
Podman enables users to move files into and out of a running container. This result is achieved using the podman cp command, which can move files and folders to and from a container. Its usage is quite simple and will be illustrated in the next example.

$ podman run -d --name alpine_cp_test alpine sleep 1000
Now, let's grab a file from the container – we have chosen the /etc/os-release file, which provides some information about the distribution and its version ID:
$ podman cp alpine_cp_test:/etc/os-release /tmp

$ cat /tmp/os-release NAME="Alpine Linux" ID=alpine VERSION_ID=3.14.2 PRETTY_NAME="Alpine Linux v3.14" HOME_URL=https://alpinelinux.org/ BUG_REPORT_URL="https://bugs.alpinelinux.org/"
In the opposite direction, we can copy files or folders from the host to...
