命令

1. k8s拉去私有仓库image

    kubectl create secret docker-registry registry-secret --docker-server=registry.cn-shenzhen.aliyuncs.com --docker-username=mengqingfang@*** --docker-password= --docker-email=mengqingfang@zingsq -n default
       
    --docker-server: 仓库地址
    --docker-username: 仓库登陆账号
    --docker-password: 仓库登陆密码
    --docker-email: 邮件地址(选填)
    -n 命名空间
       
       
       ... 
        spec:
          serviceAccountName: test
          imagePullSecrets:
          - name: registry-secret
          containers:
          - name: test
            image: registry.cn-shenzhen.aliyuncs.com/koza/test:latest
   
    kubectl create secret docker-registry registry-secret --docker-server=registry.cn-shenzhen.aliyuncs.com --docker-username=hukun@zingsq --docker-password=hukun123 --docker-email=hukun@zingsq.cn -n default
   

2. 强制删除一个pod

   kubectl delete pod xxxxxx --grace-period=0 --force
   

3. 命令行补全

   source <(kubectl completion bash)
   echo "source <(kubectl completion bash)" >> ~/.bashrc
   

4. 强制重启一个pod

    kubectl get pod install-helm  -n gitlab-managed-apps -o yaml | kubectl replace --force -f -
   

5. k8s中pod设置访问外网

   dnsPolicy: Default

    apiVersion: apps/v1
    kind: Deployment
    metadata:
      name: alpine
    spec:
      selector:
        matchLabels:
          app: alpine
      replicas: 1
      template:
        metadata:
          labels:
            app: alpine
        spec:
          containers:
          - image: alpine
            name: alpine
            command: ["top","-b"]
          dnsPolicy: Default
