Juju is an open-source tool that helps to deploy, manage, and scale applications on any cloud infrastructure. In this tutorial, we will guide you through the installation process of Juju on Fedora Server Latest.
Before starting the installation process, make sure the following prerequisites are met:
To ensure your system is up-to-date, execute the following command:
sudo dnf update
This command will install all the latest updates and packages on your system.
To install Juju, use the following commands:
sudo dnf install juju
During the installation process, you will be prompted to confirm the installation of additional packages. Type 'Y' and hit the Enter key to proceed.
After Juju is installed, initialize it with the following command:
juju init
This command will initialize Juju, create a new Juju YAML configuration file, and generate your credentials file.
You can configure Juju by editing the Juju YAML configuration file ~/.local/share/juju/credentials.yaml located in your home directory.
gedit ~/.local/share/juju/credentials.yaml
Add your cloud provider API credentials and specify your default region.
For example, the following YAML code shows a sample configuration for AWS provider:
aws:
access-key: ACCESS_KEY
secret-key: SECRET_KEY
region: us-west-2
default-region: us-west-2
Save the file and close the editor.
Next, we will bootstrap an environment. You can use the following command to add a new environment:
juju add-cloud
Then follow the instructions on the screen to configure your cloud provider.
Once you have configured your environment, use the following command to bootstrap it:
juju bootstrap
You will be prompted to confirm the bootstrap process. Type 'Y' and hit the Enter key to proceed.
After Juju is installed and the environment is initialized, you can deploy applications using Juju charms. Juju charms are pre-configured packages that describe how to deploy and configure an application.
The following command uses the 'mysql' charm to deploy a MySQL database:
juju deploy mysql
This command will deploy MySQL with default configuration.
Use the following command to view the status of your applications:
juju status
Congratulations! You have successfully installed and configured Juju on Fedora Server Latest. You can now use Juju to deploy, manage, and scale applications on any cloud infrastructure.
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!
