How to Install Salt on Fedora CoreOS Latest

Salt is an open-source configuration management tool used for automation of IT infrastructures. In this tutorial, we will learn how to install Salt on Fedora CoreOS.

Prerequisites

Before proceeding with the installation, make sure that you have:

• A running instance of Fedora CoreOS latest
• Root or sudo-level access to your instance
• Basic knowledge of the command-line interface

Step 1: Update the System

Connect to your Fedora CoreOS instance via SSH and update the system by running the following command:

sudo dnf update -y

Step 2: Install Salt

To install Salt, we need to add the SaltStack repository into the list of our system repositories. Run the following command to download and install the SaltStack repository:

sudo dnf install https://repo.saltstack.com/py3/fedora/fedora32/py3-fedora-repo-latest.noarch.rpm 

After adding the SaltStack repository, run the following command to install Salt:

sudo dnf install salt-minion -y

Step 3: Configure Salt

After installing Salt, we need to configure the Salt minion. The Salt minion is the system that receives commands from the Salt master and executes them.

To configure the Salt minion, open the /etc/salt/minion file with your preferred text editor:

sudo nano /etc/salt/minion

Update the master parameter to the IP address or the hostname of the Salt master. Add the following line:

master: <salt-master-IP>

Save and close the file.

Step 4: Start the Salt Minion Service

After configuring the Salt minion, start the Salt minion service by running the following command:

sudo systemctl start salt-minion

To make sure that the service starts automatically at boot time, run the following command:

sudo systemctl enable salt-minion

Step 5: Verify the Installation

To verify if the Salt minion is connected to the Salt master, run the following command on the Salt master:

sudo salt-key -L

This command will list all the Salt minions that have requested to connect to the Salt master. You should see your Salt minion listed.

Conclusion

In this tutorial, we have learned how to install and configure Salt on Fedora CoreOS using the SaltStack repository. We have also learned how to start and verify the Salt minion service.
