Environment variables and defaults

DH_SIZE
default: 2048 (which takes a long time to create), for demo or unsecure applications you can use smaller values like 512
SSL_DOMAIN
- the domain name you would like to run on - used to generate certificate e.g. local.dev.club.stuff

Running marvambass/nginx-ssl-secure Container

This Dockerfile is not really made for direct usage. It should be used as base-image for your nginx project. But you can run it anyways.

You should overwrite the /etc/nginx/external/ with a folder, containing your nginx *.conf files, certs and a dh.pem. If you forget the dh.pem file, it will be created at the first start - but this can/will take a long time!

localhost.conf provides an example for running local.dev.club.stuff

docker run -d \
-p 80:80 -p 443:443 \
-e 'DH_SIZE=512' \
-e 'SSL_DOMAIN=local.dev.club.stuff'
-v `pwd`/etc/nginx/:/etc/nginx/external/ \
-v [some-absolute-path]:/usr/share/nginx/html/ \
elgreg/nginx-ssl-secure:latest

Follow the output instructions for adding the new root minica CA to your OS, e.g.

sudo security add-trusted-cert -d -r trustRoot -k /Library/Keychains/System.keychain etc/nginx/minica.pem

Update your /etc/hosts to point 127.0.0.1 local.dev.club.stuff

Cheat Sheet

Creating the dh4096.pem with openssl

To create a Diffie-Hellman cert, you can use the following command

openssl dhparam -out dh4096.pem 4096

Creating a high secure SSL CSR with openssl

This cert might be incompatible with Windows 2000, XP and older IE Versions

openssl req -nodes -new -newkey rsa:4096 -out csr.pem -sha256

Creating a self-signed ssl cert

Please note, that the Common Name (CN) is important and should be the FQDN to the secured server:

openssl req -x509 -newkey rsa:4086 \
-keyout key.pem -out cert.pem \
-days 3650 -nodes -sha256
