How to Install Traefik on POP! OS Latest

Traefik is a popular open-source reverse proxy and load balancer that simplifies HTTP transactions for web applications. It enables easy communication between an HTTP client and multiple servers over a network. In this tutorial, we’ll show you how to install Traefik on POP! OS Latest.

Step 1 - Install Docker

Traefik supports Docker, which allows us to run it as a container. So, before we can install Traefik, we must install Docker first. Follow these steps to install Docker on your POP! OS Latest:

  1. Open a terminal window on your POP! OS Latest.

  2. Update the package list by running the following command:

sudo apt-get update
  1. Install the necessary packages by running the following command:
sudo apt-get install docker.io docker-compose
  1. Verify that Docker has been installed by running the following command:
docker version

You should see output that shows the installed version of Docker on your system.

Step 2 - Create a Traefik Configuration File

To use Traefik, we need to create a configuration file that specifies how it should behave. Create a new file named traefik.yml in your home directory using the following command:

nano ~/traefik.yml

Paste the following configuration into the file:

global:
  sendAnonymousUsage: true

api:
  insecure: true

entrypoints:
  web:
    address: ":80"

providers:
  docker:
    endpoint: "unix:///var/run/docker.sock"
    watch: true

log:
  level: "INFO"

This configuration enables Traefik's API, exposes the web entrypoint on port 80, and sets up a Docker provider that watches for changes.

Step 3 - Run Traefik as a Container

Now that Docker is installed and the Traefik configuration file is created, we can run Traefik as a container. Follow these steps:

  1. Open a terminal window.

  2. Run the following command to start Traefik as a container:

sudo docker run -d -p 80:80 -v /var/run/docker.sock:/var/run/docker.sock -v ~/traefik.yml:/traefik.yml traefik:v2.2

Let's break down this command:

  • -d runs the container in the background
  • -p 80:80 maps the container’s port 80 to the host’s port 80
  • -v /var/run/docker.sock:/var/run/docker.sock mount the Docker socket into the container so that it can monitor the Docker daemon
  • -v ~/traefik.yml:/traefik.yml mount the Traefik configuration file we created earlier into the container
  • traefik:v2.2 specifies which version of Traefik to run
  1. Verify that Traefik is running by running the following command:
sudo docker ps

You should see a container with the name traefik and the status Up, which means that Traefik is running.

Conclusion

Traefik is a powerful tool that simplifies managing HTTP transactions for web applications. In this tutorial, you learned how to install Traefik on POP! OS Latest using Docker. Now that you have Traefik installed, you can configure it further by specifying additional options in the traefik.yml file.
