How to Install Loki on Fedora CoreOS Latest

Loki is an open-source log aggregation system that is optimized for Kubernetes environments. In this tutorial, we will cover the steps needed to install Loki on a Fedora CoreOS Latest environment.

Prerequisites

Before we begin, you will need:

Step 1: Update Packages

First, update the package index on your Fedora CoreOS latest instance using the following command:

Then, install Loki using the following command:

sudo dnf install loki

Step 3: Configure Loki

To configure Loki, you need to edit the loki.yaml configuration file. Run the following command to open the file in your preferred text editor:

sudo nano /etc/loki/local-config.yaml

In the configuration file, you will see different sections for configuring Loki. For example, you can customize the log retention period by adjusting the retention_period parameter.

After you have made all the necessary changes, save and close the file.

Step 4: Start Loki

Now we can start Loki using systemctl.

sudo systemctl start loki

To verify that Loki has been successfully started, you can run:

sudo systemctl status loki

You should see a message indicating that Loki is running.
