NGINX-LE - Nginx web and proxy with automatic let's encrypt

Simple nginx image (alpine based) with integrated Let's Encrypt support.

How to use

get docker-compose.yml and change things:
- set timezone to your local, for example TZ=UTC. For more timezone values check /usr/share/zoneinfo directory
- set LETSENCRYPT=true if you want automatic certificate install and renewal
- LE_EMAIL should be your email and LE_FQDN for domain
- for multiple FQDNs you can pass comma-separated list, like LE_FQDN=aaa.example.com,bbb.example.com
- alternatively set LETSENCRYPT to false and pass your own cert in SSL_CERT, key in SSL_KEY and SSL_CHAIN_CERT
- use provided etc/service-example.conf to make your own etc/service.conf. Keep ssl directives as is:
```
ssl_certificate SSL_CERT;
ssl_certificate_key SSL_KEY;
ssl_trusted_certificate SSL_CHAIN_CERT;
```
make sure volumes in docker-compose.yml changed to your service config
you can map multiple custom config files in compose for any service*.conf (see docker-compose.yml for service2.conf)
pull image - docker-compose pull
if you don't want pre-built image, make you own. docker-compose build will do it
start it docker-compose up

image uses alpine's certbot package.
script/entrypoint.sh requests LE certificate and will refresh every 10 days in case if certificate is close to expiration (30day)
script/le.sh gets SSL
