My Docker Traefik configuration

Just to keep my Docker reverse-proxy configuration

Getting starting

You need to install Docker - Install Docker

And docker-compose - Install docker-compose

Installation

Install apache2-utils package

$ sudo apt-get install -y apache2-utils

Generate the password with htpasswd

$ htpasswd -nb admin your_secret_password

Use the output to configure users in your traefik.toml file

In the same file set your email for Let's Encrypt configuration and domains you want to get certificate

Create a docker network for the proxy to share with containers

$ docker network create proxy

Check that network was created

$ docker network ls

We will add others containers to this network to be proxied

Create an empty file named acme.json

$ touch acme.json

And fix the permission to this file so only root user can read and write this file.

$ chmod 600 acme.json

Then you can run "startProxy.sh" script

$ ./startProxy.sh

You will be prompted to fill a domain name. This domain will be used to access your Traefik dashboard from your browser

It's done your Traefik reverse-proxy is working. You can add docker containers to Traefik

Warnings

To be able to use labels in docker-compose.yml file you need to get the 1.16.1 docker-compose version (https://stackoverflow.com/questions/47094460/docker-compose-having-problems-with-labels)

In order to clone your project you should choose another port than 22. If you have a firewall, allow the chosen port and let the Gitlab container redirect it to port 22. (Ex: 0.0.0.0:2222 -> 22/tcp)

The clone command then will be a little different. Here's an example:

$ git clone ssh://git@git.domain.com:<port>/<team>/<project>
