如何在 k8s 的环境中设置数组结构属性？

Question

要在secret中定义clients来存储client name和password，如何在env和secret中定义一个client数组来存储这些数据？

在application.yml中应该是这样的：

app:
  clients:
    client1: password1
    client2: password2
      ......

我试图在app-deployment.yml中定义它，但似乎不允许

env:
  - name: APPLICATION_CLIENTS
    value:
      - name: client1
        valueFrom:
          secretKeyRef:
            name: clients
            key: client1-password
      - name: client2
        valueFrom:
          secretKeyRef:
            name: clients
            key: client2-password

错误：

invalid type for io.k8s.api.core.v1.EnvVar.value: got "array" expected "string"

Answer 1

创建一个 secret 并将其作为 env 安装在 pod 中，然后在代码中读取该 env var 以获取密码值和用户名的方法，而不是创建配置映射或秘密直接将其定义为 pod

中的 env var

Answer 2

Create a config map and mount that in dev as env and then in deployment.yaml format gives it is as reference :

config map creation with overriding application.yml/application.properties format as both strings or array or lists :

values.yaml :

------------------------------

 spring:
   profiles: default

 server:
   port: 8085
 management:
  endpoints:
    loggers:
      enabled: true
    web:
      exposure:
        include: loggers, health, prometheus
 sites:
      - publications: test1
      - publications: test2

config.yaml :

-------------------------

apiVersion: v1
kind: ConfigMap
metadata:
  name: {{ include "project.fullname" . }}
  labels:
    app.kubernetes.io/name: {{ include "project.fullname" . }}
    helm.sh/chart: {{ include "project.chart" . }}
    app.kubernetes.io/instance: {{ .Release.Name }}
    app.kubernetes.io/managed-by: {{ .Release.Service }}
data:
  application.yml: |-
    spring:
      profiles: {{ .Values.spring.profiles }}
    server:
      port: {{ .Values.server.port }}
    management:
      endpoints:
        loggers:
          enabled: {{ .Values.management.endpoints.loggers.enabled }}
        web:
          exposure:
            include: {{ .Values.management.endpoints.web.exposure.include }}
        sites:
{{ toYaml .Values.sites | indent 10 }} #list of items in values.yaml

deployment.yaml

-----------------------

apiVersion: apps/v1
kind: Deployment
metadata:
  name: {{ .Values.name }}
  namespace: {{ .Values.namespace }}
  labels:
    app: {{ .Values.name }}
spec:
  replicas: {{ .Values.replicaCount }}
  selector:
    matchLabels:
      app: {{ .Values.name }}
  template:
    metadata:
      annotations:
        prometheus.io/scrape: "true"
        prometheus.io/path: "/actuator/prometheus"
        prometheus.io/port: {{ .Values.server.port | quote }}
        sidecar.istio.io/inject: "false"
      labels:
        app: {{ .Values.name }}
    spec:
      volumes:
        - name: config
          configMap:
            name: {{ include "project.fullname" . }}
      containers:
        - name: {{ .Chart.Name }}
          volumeMounts:
            - name: config
              mountPath: "/app/config"
          image: {{ .Values.image.repository }}:{{ .Values.image.tag }}
          imagePullPolicy: {{ .Values.image.pullPolicy }}
          resources:
            requests:
              memory: {{ .Values.image.resources.requests.memory }}
              cpu: {{ .Values.image.resources.requests.cpu }}
            limits:
              memory: {{ .Values.image.resources.limits.memory }}
              cpu: {{ .Values.image.resources.limits.cpu }}
      imagePullSecrets:
        - name: "{{ .Values.image.imagePullSecrets }}"
    

now while running application from docker command or pom, change the path from where the application is picking config file while running. 


Example in pom : 

       <plugin>
                <groupId>com.google.cloud.tools</groupId>
                <artifactId>jib-maven-plugin</artifactId>
                <version>2.2.0</version>
                <configuration>

                    <to>
                        <image><image-url></image>
                    </to>
                    <container>
                        <creationTime>${maven.build.timestamp}</creationTime>
                        <mainClass>mypackage.MainApplication</mainClass>
                        <args>
                            <arg>--spring.config.location=/app/config/application.yml</arg>
                        </args>
                    </container>

                </configuration>
                <executions>
                    <execution>
                        <phase>package</phase>
                        <goals>
                            <goal>build</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
