simple node https redirector

node redirector.md

Redirects all http requests to https requests. Three files. Uses docker to build and run.

Once files are in place this command builds:

docker build -t node-redirector .

Run the docker image:

docker run -i --rm --name=redirector -p 80:80 node-redirector

Here are the files:
