Installing Traefik on Fedora CoreOS

Introduction

Traefik is a popular open-source tool that serves as a reverse-proxy and load-balancer for your containerized applications. With a simple configuration, Traefik can route incoming traffic to the appropriate container, while also providing services such as load-balancing, metrics, and monitoring.

In this tutorial, we will guide you through the installation process of Traefik on the latest version of Fedora CoreOS. We will be using the official Traefik Docker image, which requires Docker to be installed.

Prerequisites

Before we begin, make sure you have the following prerequisites:

• A running instance of Fedora CoreOS Latest.
• Docker installed on your system.

    [entryPoints.http.redirect]
    entryPoint = "https"
  [entryPoints.https]

[docker]
endpoint = "unix:///var/run/docker.sock"

[acme]
email = "[email protected]"

entryPoint = "https"
onHostRule = true

[[acme.domains]]

Save and close the file.

Step 2: Create a Traefik Docker Compose File

sudo mkdir /opt/traefik

Then, create a new Docker Compose file docker-compose.yml under /opt/traefik, by running the following command:

sudo nano /opt/traefik/docker-compose.yml

Copy and paste the following configuration to the file.
