Full Description

Overview

Demonstration dockerfile that shows how self-signed certificates can be securely generated at build time (or run time, with a little bit of tweaking). Deploying the image will give you a simple website running on NGINX, using the certificates that were generated during the build.

Building the image

In its most basic form, you can build the image via -
docker build --tag foo/bar .

You can also modify the contents of the generated certificate by providing one or more of the following arguments, for example:
docker build --build-arg SAN="DNS:foo.com,DNS:*.foo.com,IP:111.111.111.111" --build-arg SUBJECT="/C=US/ST=AK/L=Ketchikan/O=Evil Corp/CN=Overlord" --tag foo/bar

Argument Description Default
SAN Subject Alternative Name(s) to be added to the certificate. DNS:localhost,IP:127.0.0.1
SUBJECT Subject field to be added to the certificate. /C=AU/ST=NSW/L=Sydney/O=Localhost/CN=localhost
CN Common Name to be added to the certificate. localhost

How to Use

  1. Start a container -
    docker run -p 443:443 -d nathonfowlie/demo.createselfsignedcertificate
  2. Navigate to https://docker and gaze in wonder at my incredible web development skills.

If all goes well, you'll see an animated gif, and your browser will be complaining about trust issues :)
