  • kubernetes之十一: Secret 使用

    Secret 使用类似于 ConfigMap,支持两种形式的使用:

    • 将 Secret 作为环境变量暴露给容器进程使用。
    • 将 Secret 通过volume 数据卷提供给容器进程使用。

    为啥还要 Secret?

    Secret 顾名思义,是用于存储加密数据的

    [root@master01 template]# kubectl create secret
    Create a secret using specified subcommand.
    
    Available Commands:
      docker-registry Create a secret for use with a Docker registry
      generic         Create a secret from a local file, directory or literal value
      tls             Create a TLS secret
    

     

    案例1: 创建通用的secret

    kubectl create secret generic nginx-ssl --from-file=ca.key
    --from-file=ca.cert

    案例2: 创建docker-registry

    kubectl create secret docker-registry my-secret --docker-server=192.168.31.112  --docker-username=admin  --docker-password=123456 
    --docker-email=it@aa.com -n test

     

    案例3: 创建tls的secret

    openssl genrsa -out rest.key 2048

    openssl req -new -x509 -key rest.key -out rest.crt -subj /C=CN/ST=Beijing/L=Biejing/O=DevOpes/CN=restapi.aa.com kubectl create secret tls --cert=rest.crt --key=rest.key

      

    挂载方式

    1)通过环境变量的方式

    apiVersion: v1
    kind: Pod
    metadata:
      name: secret1-pod
    spec:
      containers:
      - name: secret1
        image: busybox
        command: [ "/bin/sh", "-c", "env" ]
        env:
        - name: USERNAME
          valueFrom:
            secretKeyRef:
              name: mysecret
              key: username
    
        - name: PASSWORD
          valueFrom:
            secretKeyRef:
              name: mysecret
              key: password
    

     

    [root@k8s-master01 ~]# kubectl create secret generic shibo-secret --from-file=./username.txt --from-file=./password.txt    
    
    
    
    apiVersion: v1
    kind: Pod
    metadata:
      name: secret-env-pod
    spec:
      containers:
      - name: mycontainer
        image: redis
        env:
          - name: SECRET_USERNAME
            valueFrom:
              secretKeyRef:
                name: shibo-secret
                key: username
          - name: SECRET_PASSWORD
            valueFrom:
              secretKeyRef:
                name: shibo-secret
                key: password
      restartPolicy: Never
    

      

     

    2)通过volumemount挂载

       volumeMounts:
          - mountPath: /home/nginx/nginx/conf/cert/
            name: nginx-ssl
    volumes:
       - name: nginx-ssl
         secret:
            secretName: nginx-ssl
    
    apiVersion: v1
    kind: Pod
    metadata:
      name: mypod
    spec:
      containers:
      - name: mypod
        image: redis
        volumeMounts:
        - name: data
          mountPath: "/etc/data"
          readOnly: true
      volumes:
      - name: data
        secret:
          secretName: shibo-secret
          items:
          - key: username
            path: my-group/my-username
    
    
    需要注意,在这种情况下:
    username 存储在 /etc/data/my-group/my-username中
