nginx

nginx-proxy

the following details how to use nginx-proxy to host multiple docker containers (nginx-proxy guide)

• create docker network

    docker network create nginx-proxy
  

• install nginx-proxy container

    docker run -d --name nginx-proxy \
        -p 80:80 \
        --net nginx-proxy \
        -v /var/run/docker.sock:/tmp/docker.sock \
        jwilder/nginx-proxy
  

letsencrypt companion

in order to use the letsencrypt companion container with nginx-proxy we need to modify the nginx-proxy run command slightly

```
docker run -d --name nginx-proxy \
	-p 80:80 -p 443:443 \
	--net nginx-proxy \
	-v /etc/nginx/certs \
	-v /etc/nginx/vhost.d \
	-v /usr/share/nginx/html \
	-v /var/run/docker.sock:/tmp/docker.sock:ro \
	jwilder/nginx-proxy
```

then we can run the letsencrypt-nginx-proxy-companion container

```
docker run -d --name nginx-proxy-letsencrypt \
	--volumes-from nginx-proxy \
	-v /var/run/docker.sock:/var/run/docker.sock:ro \
	-e "DEFAULT_EMAIL=root@pyratebeard.net" \
	jrcs/letsencrypt-nginx-proxy-companion
```

to start the application containers add the VIRTUAL_HOST and LETSENCRYPT_HOST variables using my log container as an example

```
docker run -d --name "$CONTAINER_NAME" \
    --expose 1313 \
    --net nginx-proxy \
    -e VIRTUAL_HOST=log.pyratebeard.net \
    -e LETSENCRYPT_HOST=log.pyratebeard.net \
    -v $(pwd):/src \
    $CI_REGISTRY_IMAGE
```
