Juju is an open-source application modeling tool that is used for deploying, managing, and scaling complex applications. Fedora CoreOS is a lightweight and secure operating system designed for running containerized workloads.
In this tutorial, we will show you how to install Juju on Fedora CoreOS latest version.
First, update the system and install the snap package manager with the following command:
sudo rpm-ostree install snapd
After the successful installation of the snapd package, we need to enable it. Use the following command:
sudo systemctl enable --now snapd.socket
Now that we have snapd installed and enabled on our system, we can use it to install Juju by running the following command:
sudo snap install juju --classic
Juju is now installed on our system. To initialize the Juju environment, we will run the following command:
sudo juju init
Now that Juju is installed and initialized, it's time to connect to a cloud. Juju can be used to manage your cloud-based infrastructure. For example, you can easily deploy and manage applications on public clouds like Amazon Web Services (AWS), Microsoft Azure, or Google Cloud Platform (GCP).
To authenticate with a cloud, you will need to run the following command:
sudo juju add-cloud
You will be prompted for the cloud information. Follow the instructions to add your cloud credentials.
With the Juju environment set up and connected to your cloud, you can deploy your applications. For example, if you want to deploy a web application, you can use the following command:
sudo juju deploy my-web-application
In this tutorial, we walked you through the process of installing Juju on Fedora CoreOS and connecting it to a cloud. Juju is a powerful tool that makes it easy to manage complex applications and infrastructure. Once you have mastered the basics, you can use Juju to build and deploy applications efficiently.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
