2MB HTTP to HTTPS redirect Docker microservice

I have released an ultra small 2MB HTTP to HTTPS / httpsredirect microservice which is available on Docker Hub at https://hub.docker.com/r/q4uw/httpredirector/.

The Docker image has several advantages to the existing httpsredirect images on Docker hub.

It is ultra small at 2MB
It allows both HTTPS and WWW canonical name redirection
It allows hostname redirect restriction preventing 3rd parties from using you as a redirect service.

The existing redirection images on Dockerhub allow anyone to use your server as a redirection service. This is true of geldim/https-redirect which has 500K+ pulls and camptocamp/https-redirect which has 10k+ pulls.

Basic usage

docker run --rm -ti \
  -e FORCE_SSL=TRUE \
  -e FORCE_WWW=TRUE \
  -p 80:8080 \
  q4uw/httpredirector:0.0.2

Verify it is working:

curl -I localhost
 
HTTP/1.1 307 Temporary Redirect
Date: Sat, 10 Dec 2016 07:19:01 GMT
Server: Warp/3.2.9
Location: https://www.localhost/

Full instructions and source code

Full instructions are available on the Docker hub page https://hub.docker.com/r/q4uw/httpredirector/.

The Github repository and source code is at https://github.com/ajevans85/httpredirector.

Note for Google Cloud

If you plan to use this image on Google Cloud please see https://stackoverflow.com/questions/41181496/google-cloud-mixed-http-https-application-load-balancing/ for configuring a cloud load balancer to use the redirection service which I originally developed this image for.
