Mise en place d'un serveur Traefik (Reverse Proxy)

Prérequits : 

Premièrement, à des fins de tests, nous allons générer l'image docker suivante :

Dockefile: 

# Docker Who display him name

FROM debian:latest

RUN echo "<?php" >> /var/www/html/index.php
RUN echo "\$h = getenv('HOSTNAME');" >> /var/www/html/index.php
RUN echo "echo \$h" >> /var/www/html/index.php
RUN echo "?>" >> /var/www/html/index.php
#
WORKDIR /app
VOLUME /app/logs
EXPOSE 80
CMD ["/usr/sbin/apache2ctl", "-D", "FOREGROUND"]

Création de l'image  : 

docker build  -t web_name .

Nous venons de créer une image nommée web_name. C'est un serveur web qui renvoie simplement le nom du conteneur qui l'execute. 

 

Installation et configuration de traefik :

/srv/traefik.toml :
