In this article we'll install Traefik as dynamic reverse proxy on Linux

It's recommended that you have read the previous steps of this course. You'll find the overview at the end of this blogpost.

Course ingredients:

Install Traefik as dynamic reverse proxy

First create a subdomain and point it via DNS entry to your server. You'll need the subdomain for the Traefik dashboard that monitors your services.

sudo apt-get install apache2-utils
## Install apache2-utils package, which includes an htpasswd utility for encrypted passwords

Do you want to continue? [Y/n] y

htpasswd -nb admin secure_password
## Generate encrypted password

Output in Terminal looks like this: admin:$apr1$rcda74Hq$mbjdZMZTG.KWn8vfN/SNK/

mkdir /var/traefik
## Create a folder for Traefik
cd /var/traefik
## Navigate into the new Traefik folder
nano traefik.toml 
## Create and edit file traefik.toml
    address = ":80"
      to = "websecure"
      scheme = "https"

    address = ":443"

  dashboard = true

  email = "your_email@your_domain"
  storage = "acme.json"

  watch = true
  network = "web"

  filename = "traefik_dynamic.toml"

nano traefik_dynamic.toml ## Create and edit file traefik_dynamic.toml

  users = [

  rule = "Host(`monitor.your_domain`)"
  entrypoints = ["websecure"]
  middlewares = ["simpleAuth"]
  service = "api@internal"
    certResolver = "lets-encrypt"

docker network create web ## Create a Docker network for Traefik

touch acme.json ## Create new empty file acme.json which Traefik will use for Let's Encrypt information

chmod 600 acme.json ## Grant permissions to the owner of the file only.

Start your Traefik container with the following command:

docker run -d \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v $PWD/traefik.toml:/traefik.toml \
  -v $PWD/traefik_dynamic.toml:/traefik_dynamic.toml \
  -v $PWD/acme.json:/acme.json \
  -p 80:80 \
  -p 443:443 \
  --network web \
  --name traefik \
  --restart always \

--restart always ## This option will restart the container a reboot of the server.


Stop and disable apache2 or it will block Traefik from working. Attention: If your server needs to be rebooted then apache2 will be restarted if it is not disabled.

sudo systemctl stop apache2 ## stop the service  
sudo systemctl disable apache2 ## disable the service  

Also good to know:

sudo systemctl start apache2 ## start the service  
sudo systemctl enable apache2 ## enable the service
