msolimans/icho repository overview

⁠Icho

Simple echo server that echos messages, its supports both gRPC and Http

⁠Build locally
$ git clone https://github.com/msolimans/icho 
$ cd icho 
$ go build -mod=vendor
⁠Docker
$ docker pull msolimans/icho 
$ docker run -ti --rm -p 8888:8888 -p 9999:9999 msolimans/icho
⁠Testing

Open you browser and point to http://localhost:8888/echo⁠, you should see {response: "hello world"}

If you want to override response you can do that through query string, something like

http://localhost:8888/echo?text=foo⁠

If you want to echo based on http POST, try the following:

$ curl  --request POST --data-raw '"foo message"' \
    http://localhost:8888/echo
  {"response":"foo message"}

If you want to override response through environment variable

$ docker run -ti --rm \
   -e ECHO_TEXT="foo response" \
   -p 8888:8888 -p 9999:9999 \
   msolimans/icho
$ curl http://localhost:8888/echo
{"response":"foo response"}

If you want to override ports, you can pass http and grpc ports like below

$ docker run --rm -ti \
-p 7777:7777 \
-p 6666:6666  \
msolimans/icho -http=6666 -grpc=7777

Starting REST service :6666 
Starting gRPC service :7777

If you want to try gRPC, open proto file under icho directory in any of the gRPC client tools and use port 9999

Here's gRPC Client, https://github.com/uw-labs/bloomrpc⁠

⁠For Kubernetes:

Create deployment resource:

$ touch icho.yml 
$ vim icho.yml

Add the following:

apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    run: icho
  name: icho
spec:
  replicas: 1
  selector:
    matchLabels:
      run: icho
  template:
    metadata:
      labels:
        run: icho
    spec:
      containers:
      - image: msolimans/icho
        name: icho
        ports:
        - containerPort: 8888

Create deployment:

$ kubectl create -f icho.yml

Expose deployment as a NodePort service:

$ kubectl expose deploy \
  --name ichosvc \
  --target-port=8888 --port=8888 \
  --type=NodePort \
  icho

open your browser http://localhost:8888/echo⁠

If you're using minikube, open it using:

$ minikube service ichosvc
⁠docker-compose
$ git clone https://github.com/msolimans/icho
$ cd icho 
$ docker-compose up
