含curl的 busybox

已上传至我的仓库

apiVersion: v1
kind: Pod
metadata:
  name: busybox
  namespace: default
spec:
  containers:
    - image: yauritux/busybox-curl
      command:
        - sleep
        - "3600"
      imagePullPolicy: IfNotPresent
      name: busybox
  restartPolicy: Always

常用测试命令格式

kubectl -n <namespace> exec -it <POD> -c <CONTAINER> -- <COMMAND>

貌似只有这个版本 busybox:1.28.3 nslookup 好用一些

apiVersion: apps/v1
kind: Deployment
metadata:
  name: busybox-deployment-v1
spec:
  replicas: 3
  selector:
    matchLabels:
      app: busybox-v1
  template:
    metadata:
      labels:
        app: busybox-v1
    spec:
      containers:
      - name: busybox-host
        image: busybox:1.28.3
        command: ["sleep"]
        args: ["1000"]
      #nodeName: 10.71.8.33
      #dnsPolicy: Default
      #dnsPolicy: ClusterFirstWithHostNet

也可以安装一个自己的工具容器

docker run -it --name=nginx nginx /bin/bash

mv /etc/apt/sources.list /etc/apt/sources.list.bak
echo  "deb http://mirrors.tuna.tsinghua.edu.cn/debian/ buster main contrib non-free" >/etc/apt/sources.list
echo  "deb http://mirrors.tuna.tsinghua.edu.cn/debian/ buster-updates main contrib non-free" >>/etc/apt/sources.list
echo  "deb http://mirrors.tuna.tsinghua.edu.cn/debian/ buster-backports main contrib non-free" >>/etc/apt/sources.list
echo  "deb http://mirrors.tuna.tsinghua.edu.cn/debian-security buster/updates main contrib non-free" >>/etc/apt/sources.list

apt-get update && apt-get install -y curl telnet vim iputils-ping net-tools
docker commit nginx my_nginx_image # 或者带版本号 docker commit nginx my_nginx_image:v1.0
docker save my_nginx_image -o my_nginx.tar

docker load -i my_nginx.tar
