Question

我为Kubernetes Api版本获得了一个奇怪的正则表达式验证失败 - ＆＃34; extensions / v1beta1＆＃34;在创建部署时。

kubectl --kubeconfig=/var/go/.kube/mcc-pp-config --context=sam-mcc2-pp --namespace=sam-mcc2-pp apply -f k8s-config-sam-mcc2-pp/sf-spark-worker-deployment.yaml --record

Error from server (BadRequest): error when creating "k8s-config-sam-mcc2-pp/sf-spark-worker-deployment.yaml": Deployment in version "v1beta1" cannot be handled as a Deployment: quantities must match the regular expression '^([+-]?[0-9.]+)([eEinumkKMGTP]*[-+]?[0-9]*)$'

这是我正在使用的Kubernetes yaml：

kind: Deployment
apiVersion: extensions/v1beta1
metadata:
  name: sf-spark-master
spec:
  replicas: 1
  progressDeadlineSeconds: 30
  selector:
    matchLabels:
      app: sf-spark-master
  strategy:
    type: RollingUpdate
    rollingUpdate:
      maxSurge: 1
      maxUnavailable: 0
  template:
    metadata:
      labels:
        app: sf-spark-master
        deployment: '$BUILD_VERSION'
    spec:
      containers:
        - name: sf-spark-master
          env:
            - name: ENVIRONMENT
              value: '$ENVIRONMENT'
            - name: INIT_DAEMON_STEP
              value: 'setup_spark'
          image: '$DOCKER_REGISTRY_HOST/salesiq-article-cache-stub:build-$BUILD_VERSION'
          ports:
            - containerPort: 8080
              protocol: TCP
            - containerPort: 7077
              protocol: TCP
            - containerPort: 6066
              protocol: TCP
          resources:
            limits:
              memory: '$SPARK_MASTER_MEMORY'
              cpu: '$SPARK_MASTER_CPU'

Kubectl版本的输出给出：

Client Version: version.Info{Major:"1", Minor:"6", GitVersion:"v1.6.4", GitCommit:"d6f433224538d4f9ca2f7ae19b252e6fcb66a3ae", GitTreeState:"clean", BuildDate:"2017-05-19T18:44:27Z", GoVersion:"go1.7.5", Compiler:"gc", Platform:"linux/amd64"}
Server Version: version.Info{Major:"1", Minor:"5", GitVersion:"v1.5.7", GitCommit:"8eb75a5810cba92ccad845ca360cf924f2385881", GitTreeState:"clean", BuildDate:"2017-04-27T09:42:05Z", GoVersion:"go1.7.5", Compiler:"gc", Platform:"linux/amd64"}

Answer 1

此错误是由部署YAML中使用的以下变量引起的

$BUILD_VERSION
$SPARK_MASTER_MEMORY
$SPARK_MASTER_CPU

这不是部署的apiVersion问题。

无法读取这些变量的值。

Answer 2

如果您在YAML中使用变量，则无法直接使用该YAML。

由于此$符号，它会出错。

但您可以使用envsubst命令在此问题中构建您的部署，您已在$ export ENVIRONMENT="ENV_DATA" $ export DOCKER_REGISTRY_HOST="REGISTRY" $ export BUILD_VERSION="TAG" $ export SPARK_MASTER_MEMORY="5Gi" $ export SPARK_MASTER_CPU="256Mi"命令的帮助下发布了该部署。

此命令将替换YAML中的ENV变量。

让我们说，你已经设置了这个ENVs，

deployment.yaml

现在，使用以下命令替换ENV变量并创建$ cat deployment.yaml | envsubst | kubectl create -f - deployment "sf-spark-master" created

 def store_dir
   "uploads/logo/#{model.id}"
 end

希望这会有所帮助
