gysel / go-http-echo-server

An HTTP echo server in Golang. Pretty dumb. Dumbest.

Golang HTTP Echo Server

The dumbest HTTP server you can find. Send a request and have it echoed back to you.

Usage

go run echoserver.go

Then point your browser to http://localhost:8080.

The port will be set to 8080 by default. If you want to run the server on another port, pass it using the PORT environment variable or as a parameter:

go run echoserver.go 8090

Docker

Follow the instructions below to dockerize the server.

Build image

docker build -t go-http-echo-server .

If you don't want to use the default port (8080), make sure you change that in the Dockerfile before building the image.

Run container

docker run -d -p 8080:8080 go-http-echo-server

Kubernetes

Run the bash script to push the image into a registry (localhost:32000 by default) and deploy it to Kubernetes.

./deploy.sh

Or use the existing Docker image:

IMAGE=docker.pkg.github.com/gysel/go-http-echo-server/http-echo-server
kubectl create deployment echo-server --image=$IMAGE
kubectl expose deployment echo-server --port=80 --target-port=8080

Please note that GitHub requires you to log in even when the image is public. (See https://github.community/t5/GitHub-Actions/docker-pull-from-public-GitHub-Package-Registry-fail-with-quot/td-p/32782)
