Create a Container Network

podman network create lab_net
podman network ls

Add Container to the Network

Now, when you create your containers, you simply need to add the --network lab_net flag to attach them to your new network.

Let’s create two Fedora containers, server-app and client-app, and attach them both to lab_net.

Run the first container (server-app): We’ll run this in detached mode (-d) so it stays running in the background.

podman run -dt --name server-app --network lab_net fedora

Run the second container (client-app): We’ll start this one interactively so we can immediately test the connection.

podman run -it --rm --name client-app --network lab_net fedora /bin/bash

Notice the --rm flag here. This is a handy option that automatically removes the container when you exit its shell, keeping your environment clean.

dnf install -y iputils # Installs ping
ping server-app
