Kubernetes apiVersion extensions/v1beta1 fails regex validation

1/31/2018

I'm getting a weird regex validation failure for Kubernetes Api version - "extensions/v1beta1" while creating a deployment.

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]*)
#x27;

This is the Kubernetes yaml that I'm using:

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'

The output for Kubectl version gives:

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"}

If you use variable in your YAML, you can't use that YAML directly.

Its gives error, because of this $ symbol.

But you can build your deployment from this YAML, you have posted in your question, with the help of envsubst command.

This command will replace your ENV variable in YAML.

Lets say, you have already set this ENVs,

$ export ENVIRONMENT="ENV_DATA"
$ export DOCKER_REGISTRY_HOST="REGISTRY"
$ export BUILD_VERSION="TAG"
$ export SPARK_MASTER_MEMORY="5Gi"
$ export SPARK_MASTER_CPU="256Mi"

Now, substitute ENV variable and create deployment.yaml using following command

$ cat deployment.yaml | envsubst | kubectl create -f -
deployment "sf-spark-master" created

Hope this will help

This error is caused by following variables used in deployment YAML

$BUILD_VERSION
$SPARK_MASTER_MEMORY
$SPARK_MASTER_CPU

This is not the problem of apiVersion of Deployment.

It failed to read the value of these variables.
