http-echo

HTTP Echo is a go web server that echos back the arguments given to it. This is especially useful for demos or a more extensive "hello world" application in Docker or Kubernetes.

Inspired by hashicorp/http-echo. Building multi-architecture docker images with Docker Buildx. Apple chip/arm64's users cheers :).

NOTE: There are some differences between jxlwqq/http-echo and hashicorp/http-echo:

Difference	jxlwqq/http-echo	hashicorp/http-echo
default expose port	:8080	:5678
args	"--text=hello"	"-text=hello"
build with	gin, pflag	net/http, flag
multi-platform support	yes	no

Local

The default port is 8080, but this is configurable via the --addr flag:

# go build
make go-build
# start the server
./http-echo --text="hello world" --addr=:8080

Then visit http://localhost:8080/ in your browser.

Docker

To run the server in Docker:

# docker pull
docker pull jxlwqq/http-echo:latest
# docker run
docker run -p 8080:8080 jxlwqq/http-echo:latest --text="hello world"

Then visit http://localhost:8080/ in your browser.

Kubernetes

To run the server in Kubernetes:

kubectl apply -f samples/kubernetes/hello-world/deployment.yaml
kubectl apply -f samples/kubernetes/hello-world/service.yaml
kubectl port-forward services/http-echo 8080:8080

Then visit http://localhost:8080/ in your browser.

Istio

To run the server with Istio in Kubernetes:

kubectl apply -f samples/istio/http-echo/echo-v1-deployment.yaml
kubectl apply -f samples/istio/http-echo/echo-v2-deployment.yaml
kubectl apply -f samples/istio/http-echo/echo-service.yaml

kubectl apply -f samples/istio/http-echo/istio-gateway.yaml
kubectl apply -f samples/istio/http-echo/istio-virtual-service.yaml
kubectl apply -f samples/istio/http-echo/istio-destination-rule.yaml

Then visit http://localhost in your browser.
