我目前陷入困境，不知道如何继续。

这是我的 Spring Boot application.properties

...
spring.datasource.driverClassName=org.postgresql.Driver
spring.datasource.url=jdbc:postgresql://${POSTGRES_HOST}:5432/postgres
spring.datasource.username=${POSTGRES_USER}
spring.datasource.password=${POSTGRES_PASSWORD}
spring.datasource.testWhileIdle=true
spring.datasource.validationQuery=SELECT 1
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=update
spring.jpa.hibernate.naming-strategy=org.hibernate.cfg.ImprovedNamingStrategy
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.PostgreSQLDialect

#Setup SSL
server.port: 8443
server.ssl.key-store: ${TLS_CERTIFICATE}
server.ssl.key-store-password: ${TLS_PASSWORD}
server.ssl.keyStoreType: PKCS12
server.ssl.keyAlias fundtr
...

我的 Spring Boot 应用程序部署 yaml：

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: f-app
  namespace: default
spec:
  replicas: 1
  template:
    metadata:
      name: f-app
      labels:
        app: f-app
    spec:
      containers:
      - name: f-app
        image: eu.gcr.io/..../...
        env:
          - name: POSTGRES_USER
            valueFrom:
              configMapKeyRef:
                name: postgres-config
                key: postgres_user
          - name: POSTGRES_PASSWORD
            valueFrom:
              configMapKeyRef:
                name: postgres-config
                key: postgres_password
          - name: POSTGRES_HOST
            valueFrom:
              configMapKeyRef:
                name: hostname-config
                key: postgres_host
          - name: TLS-CERTIFICATE
            valueFrom:
              secretKeyRef:
                name: f-tls
                key: Certificate.p12
          - name: TLS-PASSWORD
            valueFrom:
              secretKeyRef:
                name: f-tls
                key: password

这就是我在 Kubernetes 中创建秘密的方式：

kubectl create secret generic f-tls --from-file=Certificate.p12 --from-literal=password=changeit

当它部署时，我得到

State:         Waiting
  Reason:      CrashLoopBackOff
Last State:    Terminated
  Reason:      ContainerCannotRun
  Message:     oci runtime error: container_linux.go:247: starting container process caused "process_linux.go:295: setting oom score for ready process caused \"write /proc/13895/oom_score_adj: invalid argument\""

当我从部署 yaml 中删除 Secrets 时，它工作正常，但我不明白它是这个问题的根本原因。我正在使用谷歌云平台容器引擎。

这是我的 deployment.yaml，它使用存储在 Kubernetes 机密中的 p12 密钥和密码，就像在您的示例中一样创建。我可以进行 SSL curl 调用。我获取安装为只读卷的 p12 密钥和密码文件的内容。希望能帮助到你。

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: deployment-name
spec:
  replicas: 3
  selector:
    matchLabels:
      app: app-name

  strategy:
    rollingUpdate:
      maxSurge: 1
      maxUnavailable: 1
    type: RollingUpdate
  minReadySeconds: 30

  template:
    metadata:
      labels:
        app: app-name
    spec:
      volumes:
        - name: application
          emptyDir: {}
        - name: secrets
          secret:
            secretName: key.p12

      containers:
        - name:  php-fpm
          image: index.docker.io/docker_account/docker_image:image_tag
          imagePullPolicy: IfNotPresent
          ports:
            - containerPort: 9000

          volumeMounts:
            - name:      application
              mountPath: /app
            - name:      secrets
              mountPath: /api-p12-keys
              readOnly:  true

      imagePullSecrets:
        - name: docker-auth

这个答案特定于 Springboot 应用程序，这就是问题所在。

第 1 步：从您的密钥库或 p12 文件创建一个通用密钥

kubectl create secret generic f-tls-secret --from-file=Certificate.p12 --from-literal=password=changeit

第 2 步：使用部署对象将秘密挂载到您的 pod

spec:
  containers:
  - image: eu.gcr.io/..../...
    volumeMounts:
      - name: tls
        mountPath: /workspace/resources/

  volumes:
    - name: tls
      secret: 
        secretName: f-tls-secret
  1. 在 application.properties 文件中配置 SSL
#Setup SSL
 server.port: 8443
 server.ssl.key-store: classpath:resources/Certificate.p12
 server.ssl.key-store-password: ${TLS_PASSWORD}
 server.ssl.keyStoreType: PKCS12
 server.ssl.keyAlias fundtr
