问题描述

我已经创建了 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出，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:匹配标签:app.kubernetes.io/name:sawtooth-0模板:元数据:标签:app.kubernetes.io/name:sawtooth-0

• 为什么 selector 字段很重要?

selector 字段定义了 Deployment 如何找到要管理的 Pod.在这种情况下，您只需选择在 Pod 模板 (app.kubernetes.io/name:sawtooth-0) 中定义的标签.然而，更复杂的选择规则是可能的，只要 Pod 模板本身满足规则.

• 参考

更新:

k8s服务的apiVersion是v1:

- apiVersion: v1 # 在这里更新种类:服务元数据:app.kubernetes.io/name:sawtooth-0规格:类型:集群IP选择器:app.kubernetes.io/name: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
    ... ... ...
