HelloWorld: A Elixir Demo application

This is a very simple demo Elixir application written purely to do the fallowing things:

• Play around with Cowboy (Erlang HTTP server).
• Create a release using Distillery (maybe in combination with Docker).

More expirements may fallow (the above list will be updated).

Docker

Building the docker container and run it:

docker build --rm -t hello_world .
docker run --rm -d -p 8080:8080 -t hello_world

Creating certs (only needed if you dont use Docker)

Requirement for creating self-signed certificate is openssl. Find out if you have openssl installed by running the fallowing:

$ which openssl
/usr/bin/openssl

It returns openssl not found if you don't have openssl installed.

Creating the key and the crt files in ./cert:

$ mkdir cert && cd cert
$ openssl req -newkey rsa:2048 -nodes -keyout hello_world.key -x509 -days 365 -out hello_world.crt -subj "/C=NL/ST= /L= /O= /CN= "

TODO

• Use a self-signed SSL sertificate so I can serve using HTTPS.
• Use Docker.
• Remove Server Response Header using a Cowboy Stream.
• Redirect http to https.
• Create a docker-compose file.
• Use Conform for setting run-time configuration. (Experimented with it, but at this time not needed.)
