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。
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
$ kubectl run nginx --image hub.hlc.com/library/myapp:v1 pod/nginx created $ kubectl get pods NAME READY STATUS RESTARTS AGE testnuinx 1/1 Running 0 105s $ kubectl exec nginx -- ls /run/secrets/kubernetes.io/serviceaccount ca.crt namespace token
I、创建说明
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
secrets.yml
apiVersion: v1
kind: Secret
metadata:
name: mysecret
data:
password: MWYyZDFlMmU2N2Rm
username: YWRtaW4=
II、使用方式
1、将 Secret 挂载到 Volume 中
apiVersion: v1 kind: Pod metadata: labels: name: seret-test name: seret-test spec: volumes: - name: secrets secret: secretName: mysecret containers: - image: hub.hlc.com/library/myapp:v1 name: db volumeMounts: - name: secrets mountPath: "readOnly: true" readOnly: true
II、使用方式1、将 Secret 挂载到 Volume 中2、将 Secret 导出到环境变量中
apiVersion: apps/v1 kind: Deployment metadata: name: pod-deployment spec: replicas: 2 selector: matchLabels: app: pod-deployment template: metadata: labels: app: pod-deployment spec: containers: - name: pod-1 image: hub.hlc.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
$ kubectl exec pod-deployment-5877f7ddf8-rhs5j -it -- bash $ echo $TEST_USER admin $ echo $TEST_PASSWORD 1f2d1e2e67df
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_EMAIL secret "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
