ValidationError:缺少必填字段“选择器"在io.k8s.api.v1.DeploymentSpec中 [英] ValidationError: missing required field "selector" in io.k8s.api.v1.DeploymentSpec

问题描述

我创建了Hyper-V机器，并尝试使用Sawtooth YAML文件在Minikube上部署Sawtooth:

解决方案

您需要修复部署 yaml 文件.从错误消息中可以看到， Deployment.spec.selector 字段不能为空.

更新 yaml (即添加 spec.selector )，如下所示:

 规范:复制品:1选择器:matchLabels:app.kubernetes.io/名称:sawtooth-0模板:元数据:标签:app.kubernetes.io/名称:sawtooth-0 

• 为什么 selector 字段很重要?

选择器字段定义部署如何查找要管理的Pod.在这种情况下，您只需选择在Pod模板中定义的标签( app.kubernetes.io/name:sawtooth-0 ).但是，只要Pod模板本身满足该规则，就可以使用更复杂的选择规则.

更新:

k8s服务的 apiVersion 是 v1 :

 <代码>-apiVersion:v1#在此处更新种类:服务元数据:app.kubernetes.io/名称:sawtooth-0规格:类型:ClusterIP选择器:app.kubernetes.io/名称:sawtooth-0…… 

I've created Hyper-V machine and tried to deploy Sawtooth on Minikube using Sawtooth YAML file : https://sawtooth.hyperledger.org/docs/core/nightly/master/app_developers_guide/sawtooth-kubernetes-default.yaml

I changed the apiVersion i.e. apiVersion: extensions/v1beta1 to apiVersion: apps/v1, though I have launched Minikube in Kubernetes v1.17.0 using this command

minikube start --kubernetes-version v1.17.0

After that I can't deploy the server. Command is

kubectl apply -f sawtooth-kubernetes-default.yaml --validate=false

It shows an error with "sawtooth-0" is invalid.

解决方案

You need to fix your deployment yaml file. As you can see from your error message, the Deployment.spec.selector field can't be empty.

Update the yaml (i.e. add spec.selector) as shown in below:

  spec:
    replicas: 1
    selector:
      matchLabels:
        app.kubernetes.io/name: sawtooth-0
    template:
      metadata:
        labels:
          app.kubernetes.io/name: sawtooth-0

• Why selector field is important?

The selector field defines how the Deployment finds which Pods to manage. In this case, you simply select a label that is defined in the Pod template (app.kubernetes.io/name: sawtooth-0). However, more sophisticated selection rules are possible, as long as the Pod template itself satisfies the rule.

• Reference

Update:

The apiVersion for k8s service is v1:

- apiVersion: v1 # Update here
  kind: Service
  metadata:
    app.kubernetes.io/name: sawtooth-0
  spec:
    type: ClusterIP
    selector:
      app.kubernetes.io/name: sawtooth-0
    ... ... ...
