部署无效:spec.template.metadata.labels:值无效

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:

部署"moverick-mule-pre"无效:spec.template.metadata.labels:无效值:map [string] string {"commit":"750a26deebc3582bec4bfbb2426b3f22ee042eaa","app":"moverick-mule-pre"}:selector与模板不匹配 labels

我的yaml文件是:

apiVersion: apps/v1beta1
kind: Deployment
metadata:
  name: moverick-mule-pre
spec:
  replicas: 2
  strategy:
    type: RollingUpdate
    rollingUpdate:

      maxUnavailable: 1
  template:
    metadata:
      labels:
        app: moverick-mule-pre

apiVersion: v1
kind: Service
metadata:
  name: moverick-mule-pre
spec:
  ports:
  - port: 80
  selector:
    app: moverick-mule-pre

Answer 1

您需要添加selector的spec部署.

而且,这些selector应该与labelsPodTemplate相匹配.

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,您将收到如下错误

部署"moverick-mule-pre"无效:

• spec.selector:必需的值
• spec.template.metadata.labels:无效值:map [string] string {...} selector与模板不匹配labels
