Test
Test the setup by running a "podman run hello-world" command.
[root@podman root]#podman run hello-world
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash

About Manas Ranjan Tripathy
You're actually installing the podman from ol7_developer, and not ol7_addons repo that you're enabling. You may want to mention the need to add and/or enable the dev repo!
