Simple REST Service that echos the requests back. This service runs inside a container so there is almost no overhead in getting started.
- Easy test reverse proxy routes and paths.
- Use this service as a dummy to see if request reach your service correctly.
- Use it to test load balancers by peeking at the out and see the host/ip.
- Use it for Hello World demo projects that respond the request back.
docker run -ti --rm -p 5050:5050 vad1mo/hello-world-rest
Be patient, because it takes some time until all dependencies are downloaded and the container actually repsonses to requests.
> curl localhost:5050/foo/bar
