Dockerized nginx image with letsencrypt image integrated

Nginx-letsencrypt

This is a nginx docker image with letsencrypt implemented. Before starting the nginx deamon, this image will check if certificates for the hostname domain. If there is a certificate, it will do a certbot renew command to check if the certificates needs to renew it and renew it when needed. If the certificate is not the it will create it and other domains in the environment variable LETS_ENCRYPT_DOMAINS with the email in the LETS_ENCRYPT_EMAIL variable as the lets encrypt registration and recovery contact. The environment variable LETS_ENCRYPT_DOMAINS can be a comma separated list of domains that should be in the certificate.
