Beginner, Docker, Traefik, Tutorial

Intro

After a Basic Setup with fix Configuration, here an example where we put some Variables in a “.env” File.

Requirements:

Linux Host with Docker see here, Public IP Adress and rechable Port 80 & 443

two FQDN pointing to your IP:

  • traefik.yourdomain.de
  • whoami.yourdomain.de

Env Vars

let’s run the following Commands which generates a “.env” File. It will also create a User “dashboard” and ask you twice for the Password

echo 'domain="your.domain.de"'      > .env
echo 'traefik="traefik.${domain}"'  >> .env
echo 'whoami="whoami.${domain}"'    >> .env
echo 'mail="name@${domain}"'        >> .env
echo -n 'dashboardaccount="' >> .env; echo -n $(htpasswd -nB dashboard) |sed -e s/\\$/\\$\\$/g >> .env; echo '"' >> .env

.env

and here is the Content of my .env File.
