onaci/echo

A simple container-service that echoes HTTP(s) request information to the response body

go-echo

Simple golang HTTP echo server. Also has a Prometheus metrics endpoint at http://localhost:2112/metrics.

Can be used as a container image:

docker run -dit -p 80:80 -p 2112:2112 cirri/echo:latest

For use with cirri --infra (using caddy, caddy-docker-proxy and some DNS magic):

docker run -dit --network cirri_proxy \
		--name echo_dev \
			cirri/echo:latest

maps the echo to `https://echo_dev.${STACKDOMAIN}` and the metrics to `https://echo_dev.${STACKDOMAIN}/metrics` using the `virtual.port` and `virtual.metrics` labels in the image.

Quickstart

    go run echo.go -p 8080

Click http://localhost:8080/hello and the response should be similar to this:

    {
        "Body": {
            "String": ""
        },
        "ContentLength": 0,
        "Header": {
            "Accept": [

            ],

            "User-Agent": [
                "HTTPie/0.9.4"
            ]
        },
