Nginx – Lets encrypt SSL certificate in Docker container via nginx-proxy

Apache2dockerdocker-composenginxssl

currently I am using nginx-proxy to route my subdomains to different docker containers. Now, I would like to add a SSL certifcate to my Owncloud container but I am failing to set it up correctly.

What I have done:

  1. Getting a certificate via certbot

I tried to get a SAN certificate by executing ./certbot-auto certonly where I have entered every single subdomain I would like to use. The certificate was generated successfully into etc/letsencrypt/live/www.mydomain.com

  1. Mounting the certificate to the owncloud container and setting up nginx-proxy

Have a quick look at my docker-compose.yml:

nginx-proxy:
  image: jwilder/nginx-proxy
  ports:
  - "80:80"
  - "443:443"
  volumes:
  - /var/run/docker.sock:/tmp/docker.sock

owncloud:
  image: owncloud
  expose:
  - 80
  - 443
  environment:
  - "VIRTUAL_HOST=owncloud.mydomain.com,www.owncloud.mydomain.com"
  - "VIRTUAL_PROTO=https"
  - "VIRTUAL_PORT=443"
  volumes:
  - "owncloud-data:/var/www/html"
  - "/etc/letsencrypt/live/www.mydomain.com:/root/ssl"

And here is an excerpt of my /etc/apache2/sites-available/default-ssl.conf (of course the one from the owncloud container)

<IfModule mod_ssl.c>
    <VirtualHost _default_:443>
            ServerAdmin webmaster@localhost

            DocumentRoot /var/www/html

            ErrorLog ${APACHE_LOG_DIR}/error.log
            CustomLog ${APACHE_LOG_DIR}/access.log combined

            SSLEngine on

            SSLCertificateFile      /root/ssl/cert.pem
            SSLCertificateKeyFile /root/ssl/privkey.pem
            <FilesMatch "\.(cgi|shtml|phtml|php)$">
                            SSLOptions +StdEnvVars
            </FilesMatch>
            <Directory /usr/lib/cgi-bin>
                            SSLOptions +StdEnvVars
            </Directory>

            BrowserMatch "MSIE [2-6]" \
                            nokeepalive ssl-unclean-shutdown \
                            downgrade-1.0 force-response-1.0
            # MSIE 7 and newer should be able to use keepalive
            BrowserMatch "MSIE [17-9]" ssl-unclean-shutdown

    </VirtualHost>
</IfModule>

Whenever I try to connect to https://www.owncloud.mydomain.com I get the ERR_CONNECTION_REFUSED error.

Any ideas? Thank you.

Finally, I found out that my docker-compose.yaml was not correct. Here is my new config:

nginx-proxy:
  image: jwilder/nginx-proxy
  ports:
  - "80:80"
  - "443:443"
  volumes:
  - /var/local/nginx/certs:/etc/nginx/certs
  - /etc/letsencrypt:/etc/letsencrypt
  - /var/run/docker.sock:/tmp/docker.sock

owncloud:
  image: owncloud
  expose:
  - 443
  environment:
  - "VIRTUAL_HOST=owncloud.mydomain.com,www.owncloud.mydomain.com"
  volumes:
  - "owncloud-data:/var/www/html"

A link to my fullchain.pem and privkey.pem is within /var/local/nginx
