Ansible galaxy role to deploy Traefik in docker

The purpose of this Ansible role is to allow you to manage a Traefik reverse proxy.

With this role you will be able to generate deploy a Traefik container on you server, configure desired HTTP/HTTPS redirections and generate HTTPS associated certificates (thanks to Let's Encrypt).

Requirements

The following packages have to be installed and well configured on the host :

• Docker-ce

Role Variables

  endpoint_name:
    # Fontend match on host to trigger the redirection
    host: "test.localhost"
    # Backend url to redirect to

    # If true generate let's encrypt certificate for specified host
    host_gen_cert: true
