Service that prints the received HTTP headers in JSON

Use the container

It's a simple docker container that listens on 8080

You can build it yourself or use the latest image hosted at dockerhub:

docker run -p 8080:8080 javipolo/http-show-headers:latest

and test

$ curl http://localhost:8080
{
  "Accept": "*/*", 
  "Content-Length": "", 
  "Content-Type": "text/plain", 
  "Host": "localhost:8080", 
  "User-Agent": "curl/7.58.0"
}

Deploy or upgrade in kubernetes with helm

Copy or modify values.yaml and deploy as usual:

helm upgrade -i http-show-headers -f values.yaml helm/

and test

$ curl https://your-hostname.org/http-show-headers
{
  "Accept": "*/*", 
  "Accept-Encoding": "gzip",
