deployment - 部署无效:spec.template.metadata.labels:无效值

Question

将我的服务部署到生产中:

envsubst < ./kubernetes/pre-production/aks.yaml | kubectl apply -f -

我收到以下错误:

The Deployment "moverick-mule-pre" is invalid: spec.template.metadata.labels: Invalid value: map[string]string{"commit":"750a26deebc3582bec4bfbb2426b3f22ee042eaa", "app":"moverick-mule-pre"}: selector does not match template labels

我的yaml文件是:

apiVersion: apps/v1beta1
kind: Deployment
metadata:
  name: moverick-mule-pre

  replicas: 2
  strategy:
    type: RollingUpdate
    rollingUpdate:

apiVersion: v1

您需要在Deployment的selector中添加spec。
而且，这些selector应该与PodTemplate中的labels匹配。

apiVersion: apps/v1beta1
kind: Deployment
metadata:
  name: moverick-mule-pre
spec:
  replicas: 2
  selector:
    matchLabels:
      app: moverick-mule-pre
      commit: $CI_COMMIT_SHA
  strategy:
    type: RollingUpdate
    rollingUpdate:
      maxSurge: 1
      maxUnavailable: 1
  template:
    metadata:
      labels:
        app: moverick-mule-pre
        commit: $CI_COMMIT_SHA

否则，您将得到如下错误

The Deployment "moverick-mule-pre" is invalid:

• spec.selector: Required value
• spec.template.metadata.labels: Invalid value: map[string]string{...} selector does not match template labels
