我目前正在为OpenShift设计模板,并且在我初始化实例化应用程序时,我的ImageChange触发器被删除了。我的模板包含以下对象

  • ImageStream
  • BuildConfig
  • 服务
  • 路线
  • Deploymentconfig

我想这条路线是不相关的,但是到目前为止,它看起来是这样(为了更好地概述,我将对象分离开来,但是它们都是我模板中的所有项目)

ImageStream

- kind: ImageStream 
    apiVersion: v1
    metadata:
      labels:
        app: my-app
      name: my-app
      namespace: ${IMAGE_NAMESPACE}

BuildConfig

- kind: BuildConfig
    apiVersion: v1
    metadata:
      labels:
        app: my-app
        deploymentconfig: my-app
      name: my-app
      namespace: ${IMAGE_NAMESPACE}
      selfLink: /oapi/v1/namespaces/${IMAGE_NAMESPACE}/buildconfigs/my-app
    spec:
      runPolicy: Serial
      source:
        git:
          ref: pre-prod
          uri: 'ssh://git@git.myreopo.net:port/project/my-app.git'
        sourceSecret:
          name: git-secret
        type: Git
      strategy:
        type: Source
        sourceStrategy:
          env:
            - name: HTTP_PROXY
              value: 'http://user:password@proxy.com:8080'
            - name: HTTPS_PROXY
              value: 'http://user:password@proxy.com:8080'
            - name: NO_PROXY
              value: .something.net
          from:
            kind: ImageStreamTag
            name: 'nodejs:8'
            namespace: openshift
      output:
          to:
            kind: ImageStreamTag
            name: 'my-app:latest'
            namespace: ${IMAGE_NAMESPACE}

服务

- kind: Service
    apiVersion: v1
    metadata:
      name: my-app
      labels:
        app: my-app
    spec:
      selector:
        deploymentconfig: my-app
      ports:
        - name: 8080-tcp
          port: 8080
          protocol: TCP
          targetPort: 8080
      sessionAffinity: None
      type: ClusterIP

DeploymentConfig

现在DeploymentConfig中已经很奇怪的是,在spec.template.spec.containers [0] .image下,我必须指定存储库的完整路径以使其正常工作,否则在提取图像时会出错。 (即使文档说my-app:latest是正确的)

- kind: DeploymentConfig
    apiVersion: v1
    metadata:
      labels:
        app: my-app
        deploymentconfig: my-app
      name: my-app
      namespace: ${IMAGE_NAMESPACE}
      selfLink: /oapi/v1/namespaces/${IMAGE_NAMESPACE}/deploymentconfigs/my-app
    spec:
      selector:
        app: my-app
        deploymentconfig: my-app
      strategy:
        type: Rolling
        rollingParams:
          intervalSeconds: 1
          maxSurge: 25%
          maxUnavailability: 25%
          timeoutSeconds: 600
          updatePeriodSeconds: 1
      replicas: 1
      template:
        metadata:
          labels:
            app: my-app
            deploymentconfig: my-app
        spec:
          containers:
            - name: my-app-container
              image: "${REPOSITORY_IP}:${REPOSITORY_PORT}/${IMAGE_NAMESPACE}/my-app:latest"
              imagePullPolicy: Always
              ports:
                - containerPort: 8080
                  protocol: TCP
                - containerPort: 8081
                  protocol: TCP
              env:
                - name: MONGODB_USERNAME
                  valueFrom:
                    secretKeyRef:
                      name: my-app-database
                      key: database-user
                - name: MONGODB_PASSWORD
                  valueFrom:
                    secretKeyRef:
                      name: my-app-database
                      key: database-password
                - name: MONGODB_DATABASE
                  value: "myapp"
                - name: ROUTE_PATH
                  value: /my-app
                - name: MONGODB_AUTHDB
                  value: "myapp"
                - name: MONGODB_PORT
                  value: "27017"
                - name: HTTP_PORT
                  value: "8080"
                - name: HTTPS_PORT
                  value: "8082"
        restartPolicy: Always
        dnsPolicy: ClusterFirst
        triggers:
          - type: ImageChange
            imageChangeParams:
              automatic: true
              from: 
                kind: ImageStreamTag
                name: 'my-app:latest'
                namespace: ${IMAGE_NAMESPACE}
              containerNames:
                - my-app-container
          - type: ConfigChange

我使用部署应用程序

oc process -f ./openshift/template.yaml ..Parameters... | oc apply -f -

但是当我使用oc new-app时,结果是一样的。

奇怪的是。该应用程序已部署并且运行良好,但是映像更改将无效。因此,我导出了DeploymentConfig,发现它缺少ImageChangeTrigger,而触发器部分处于

triggers:
  - type: ConfigChange

起初,我认为这是由于以下事实:当我尝试应用DeploymentConfig时,可能尚未构建完成,因此我首先创建了一个构建并等待其完成。之后,我部署了其余的应用程序(Service,Route,DeploymentConfig)。结果是一样的。如果我使用Webgui并从中更改DeploymentConfig

为此,填写名称空间,应用程序和标签(最新),然后点击应用所有应有的功能。我只是不知道为什么最初会忽略触发器。如果有人知道我错了,那就太好了

我使用的版本是

oc:v3.9.0

kubernetes:1.6.1版

openshift v3.6.173.0.140

答案 0 :(得分:1)

好的,答案很简单。原来,这只是DeploymentConfig的yaml文件中的缩进错误。代替

    dnsPolicy: ClusterFirst
    restartPolicy: Always
    terminationGracePeriodSeconds: 30
    triggers:
      - type: ImageChange
        imageChangeParams:
          automatic: true
          containerNames:
            - alpac-studio-container
          from:
            kind: ImageStreamTag
            name: alpac-studio:latest
      - type: ConfigChange

必须是

    dnsPolicy: ClusterFirst
    restartPolicy: Always
    terminationGracePeriodSeconds: 30
triggers:
  - type: ImageChange
    imageChangeParams:
      automatic: true
      containerNames:
        - alpac-studio-container
      from:
        kind: ImageStreamTag
        name: alpac-studio:latest
  - type: ConfigChange

因此,触发器必须与例如模板和策略
