制作 hey 镜像

1. 容器中执行 go get

docker run golang go get -v github.com/rakyll/hey

2. 将容器打镜像

docker commit $(docker ps -lq) zhaojizhuang66/heyimage

3. docker 中使用

docker run zhaojizhuang66/heyimage hey -n 10 -c 2 'https://json-head.now.sh/'

4. k8s 中使用

kubectl apply -f - <<EOF
apiVersion: v1
kind: Pod
metadata:
  labels:
    run: hey
  name: hey
spec:
  containers:
    # This could be any image that we can SSH into and has curl. radial/busyboxplus:curl
  - image: zhaojizhuang66/heyimage
    imagePullPolicy: IfNotPresent
    name: hey
    resources: {}
    stdin: true
    tty: true

等待 Pod Ready 后执行

kubectl exec -it hey bash

root@hey:/# hey -n 10 -c 2 'https://json-head.now.sh/'
