Traefik is a popular reverse proxy and load balancer that supports automatic discovery of services, dynamic configuration, and Let's Encrypt integration. In this tutorial, we will guide you through the steps to install Traefik on Kali Linux.
Before we proceed, make sure that you have the following:
Traefik is designed to run in a Docker container, so we need to first install Docker. Run the following command in your terminal:
sudo apt-get update
sudo apt-get install docker.io
After the installation is complete, start the Docker service using the following command:
sudo systemctl start docker
You can verify that Docker is running by running the following command:
sudo docker ps
This should display the list of running Docker containers.
Docker Compose is a tool for defining and running multi-container Docker applications. It allows us to define the Traefik service and its dependencies in a configuration file. To install Docker Compose, run the following command in your terminal:
sudo apt-get install docker-compose
Next, we need to create a Traefik configuration file. Create a new file called docker-compose.yml and paste the following code:
version: '3'
services:
traefik:
image: traefik:v2.5
command:
- --providers.docker=true
- --api.dashboard=true
- --providers.docker.exposedbydefault=false
- --entrypoints.web.address=:80
ports:
- '80:80'
- '8080:8080'
volumes:
- /var/run/docker.sock:/var/run/docker.sock
This configuration file defines a traefik service that uses the official Traefik Docker image. It also sets up Traefik to listen on port 80 for incoming requests and on port 8080 for the Traefik dashboard. Lastly, it maps the Docker Unix socket into the container so that Traefik can discover other services.
Now that everything is set up, it's time to start Traefik. Run the following command in the same directory where you created the docker-compose.yml file:
sudo docker-compose up -d
This command starts the Traefik service in the background (-d) and prints the container ID.
You can verify that Traefik is running by visiting http://localhost:8080/dashboard/ in your web browser. This should display the Traefik dashboard.
Congratulations! You have successfully installed Traefik on Kali Linux using Docker and Docker Compose. You can now use Traefik to reverse proxy and load balance your services.
Note: Make sure to secure the dashboard using appropriate authentication methods, as it provides access to your Traefik configuration.
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!
