Secret 解决了密码、token、密钥等敏感数据的配置问题,而不需要把这些敏感数据暴露到镜像或者 Pod Spec中。Secret 可以以 Volume 或者环境变量的方式使用
① Service Account:用来访问 Kubernetes API,由 Kubernetes 自动创建,并且会自动挂载到 Pod 的/run/secrets/kubernetes.io/serviceaccount目录中
② Opaque:base64编码格式的Secret,用来存储密码、密钥等
③ kubernetes.io/dockerconfigjson:用来存储私有 docker registry 的认证信息
Service Account 用来访问 Kubernetes API,由 Kubernetes 自动创建,并且会自动挂载到 Pod的/run/secrets/kubernetes.io/serviceaccount目录中
Opaque 类型的数据是一个 map 类型,要求 value 是 base64 编码格式:
$ echo-n"admin" | base64 YWRtaW4=
$ echo-n"1f2d1e2e67df" | base64 MWYyZDFlMmU2N2Rm
解密

secrets.yml
apiVersion: v1 kind: Secret metadata: name: mysecret type: Opaque data: password: MWYyZDFlMmU2N2Rm username: YWRtaW4= |
apiVersion: v1 kind: Pod metadata: labels: name: seret-test name: seret-test spec: volumes: - name: secrets secret: secretName: mysecret containers: - image: hub.atguigu.com/library/myapp:v1 name: db volumeMounts: - name: secrets mountPath: " readOnly: true |
apiVersion: extensions/v1beta1 kind: Deployment metadata: name: pod-deployment spec: replicas: 2 template: metadata: labels: app: pod-deployment spec: containers: - name: pod-1 image: hub.atguigu.com/library/myapp:v1 ports: - containerPort: 80 env: - name: TEST_USER valueFrom: secretKeyRef: name: mysecret key: username - name: TEST_PASSWORD valueFrom: secretKeyRef: name: mysecret key: password |
使用 Kuberctl 创建 docker registry 认证的 secret
$ kubectl create secret docker-registry myregistrykey --docker-server=DOCKER_REGISTRY_SERVER --docker-username=DOCKER_USER --docker-password=DOCKER_PASSWORD --docker-email=DOCKER_EMAILsecret "myregistrykey" created. |
在创建 Pod 的时候,通过imagePullSecrets来引用刚创建的 `myregistrykey
apiVersion: v1 kind: Pod metadata: name: foo spec: containers: - name: foo image: roc/awangyang:v1 imagePullSecrets: - name: myregistrykey |
