Servidor intermediari invers

Using Docker to Set up Nginx Reverse Proxy With Auto SSL Generation

Ús del docker

Crida a un servidor nginx (https://sub.things.cat):

docker run --rm --name nginx-dummy -e VIRTUAL_HOST=sub.things.cat -e LETSENCRYPT_HOST=sub.things.cat -e VIRTUAL_PORT=80 --network net -d nginx:latest

Crida a un servidor NextCloud (https://sub0.things.cat/):

docker run --name nextcloud0 --network net -e VIRTUAL_HOST="sub0.things.cat" -e LETSENCRYPT_HOST="sub0.things.cat" -d nextcloud:19.0.2

Accés a la consola bash del docker nextcloud0:

docker exec -it nextcloud0 bash -l

Per a obtenir la informació disponible del docker en funcionament:

docker inspect nextcloud0

Per a obtenir la IP interna del docker en funcionament:

docker inspect nextcloud0 | grep IPAddress

docker-compose.yml

Abans de posar en marxa el docker cal crea la xarxa que connecta el reverse-proxy amb letsencrypt:

docker network create net

Podeu veure quins dockers són connectats a la xarxa interna:

docker network inspect net

Un cop heu copiat l'arxiu docker-compose.yml a una carpeta del sistema:

docker-compose up -d
