Hello World REST Service

Simple REST Service that echos the requests back. This service runs inside a container so there is almost no overhead in getting started.

What is this sevice good for?

• 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.

Start

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.

Example

> curl localhost:5050/foo/bar
/:path1/:path2 - Hello to foo/bar ! Host:0bd595c5b46a/172.18.0.3

Usage

Send request to curl localhost:5050/xx/yy and see it bouncing back.

Responses

    render "/ - Hello World! Host:${InetAddress.getLocalHost()}"

}

    render "/:path1/:path2 - Hello to $pathTokens.path1/$pathTokens.path2 ! Host:${InetAddress.getLocalHost()}"
}
get("/:path1/:path2/:path3") {
    render "/:path1/:path2/:path3 - Hello to $pathTokens.path1/$pathTokens.path2/$pathTokens.path3 ! Host:${InetAddress.getLocalHost()}"
}
