Bonjour,
je viens vers vous pour avoir quelques informations.
J'ai lu beaucoup ces derniers temps, et je vois que beaucoup utilise le couple Traefik / Nginx
Il y a t'il une raison à cela ?
Si oui, je suis entrain de tenter de faire un docker-compose qui fasse cohabiter tout cela.
Mais, je n'y arrive pas.
J'utilise le travail de Hardware au niveau de traefik.
Je tente d'y intégrer un Nginx pour l'utilisation de Nextcloud / Wordpress et autre.
C'est vraiment du test et pour tenter de comprendre.
De cette manière j'accède bien à rainloop.
Mais pour la parti webserver, j'ai juste crée un fichier de base html, mais je tombe sur un Bad Gateway
