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 |
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.
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.
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.
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.
