Install podman & useful podman commands

I would show you how to install podman the alternative docker. The difference between docker and podman is

  • docker: Running the docker daemon to operate the containers.
  • podman: Do not need to run a daemon to operate the containers. As a initial setting, users need to run it by root authority. But after a setting, they can use podman from user authority. That's useful.

How to install and run podman with rootless

On Fedora

$ sudo dnf install -y podman

Then to run podman from user authority, add below lines to the files

$ cat /etc/subuid
...
your_account_name:100000:65536
$ cat /etc/subgid
...
your_account_name:100000:65536

There a compatibility between them, just replacing docker something with podman something. But podman does not support docker-compose.

$ podman info --debug
