NGINX-PROXY

nginx-proxy sets up a container running nginx and docker-gen. docker-gen generates reverse proxy configs for nginx and reloads nginx when containers are started and stopped.

See Automated Nginx Reverse Proxy for Docker for why you might want to use this.

Nginx-proxy Usage - to enable SSL support

To use it with original nginx-proxy container you must declare 3 writable volumes from the nginx-proxy container:

• /etc/nginx/certs to create/renew Let's Encrypt certificates
• /etc/nginx/vhost.d to change the configuration of vhosts (needed by Let's Encrypt)
• /usr/share/nginx/html to write challenge files.

Example of use:

• First start nginx with the 3 volumes declared:

$ docker run -d -p 80:80 -p 443:443 \
    --name nginx-proxy \
    -v /path/to/certs:/etc/nginx/certs:ro \
    -v /etc/nginx/vhost.d \
    -v /usr/share/nginx/html \
    -v /var/run/docker.sock:/tmp/docker.sock:ro \
    --label com.github.jrcs.letsencrypt_nginx_proxy_companion.nginx_proxy \
    jwilder/nginx-proxy

The "com.github.jrcs.letsencrypt_nginx_proxy_companion.nginx_proxy" label is needed so that the letsencrypt container knows which nginx proxy container to use.

• Second start this container:

$ docker run -d \
    -v /path/to/certs:/etc/nginx/certs:rw \
    -v /var/run/docker.sock:/var/run/docker.sock:ro \
    --volumes-from nginx-proxy \
    jrcs/letsencrypt-nginx-proxy-companion

Then start any containers you want proxied with a env var VIRTUAL_HOST=subdomain.youdomain.com

$ docker run -e "VIRTUAL_HOST=foo.bar.com" ..
