To start off, log into your server and refresh the local package index as follows.

$ sudo apt update

2) Install Cockpit Web Console

The Cockpit web console packages are provided by the official Ubuntu repositories. You can verify this by running the following command.

$ apt search cockpit

So, install Cockpit using the APT package manager as shown.

$ sudo apt install cockpit -y

The command installs the Cockpit web console alongside other additional packages, libraries, and dependencies.

Once installed, you can verify if cockpit is installed by running the following command:

$ apt -qq list cockpit
OR

In case, you planning to manage kvm virtual machines with cockpit then install following package

3) Install Cockpit Support for Podman

By default, Cockpit does not provide support for podman. If you wish to administer and manage podman containers using Cockpit, install the cockpit-podman package which provides support for podman.

$ sudo apt install cockpit-podman y

4) Start Cockpit Web Console Service

Unlike other services or daemons, Cockpit does not start automatically once installed. Therefore, start the Cockpit systemd service as shown.

$ sudo systemctl start cockpit

Next, verify that the Cockpit service is running as follows.

$ sudo systemctl status cockpit

The output confirms that the Cockpit service is up and running.

Cockpit listens on TCP port 9090. You can verify this is the case by running the following ss command.

$ ss -tunlpe | grep cockpit

If the firewall is enabled on your Ubuntu 22.04 system, then allow 9090/tcp port so it’s web console can be accessed from outside

$ sudo ufw allow 9090/tcp
$ sudo ufw reload

5) Access Cockpit Web Console

Cockpit is now fully installed and the only thing remaining is to access it and use it to manage your server.

To access Cockpit Web console, browse the following address.

https://server-ip:9090

You will get a warning that the website you are accessing is not private and that you could fall victim to hackers. Do not fret, as this happens since the server is encrypted by a self-signed SSL certificate which is not recognized by CA.
