部署到kubernetes

Question

我想在kubernetes上部署前端和后端应用。我写了yaml文件(我从 helm temlate中得到的)。

# Source: quality-control/templates/ingress.yaml
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: RELEASE-NAME-quality-control
  labels:
    app.kubernetes.io/name: quality-control
    helm.sh/chart: quality-control-0.1.0
    app.kubernetes.io/instance: RELEASE-NAME
    app.kubernetes.io/managed-by: Tiller
spec:
  rules:
    - host: "quality-control.ru"
      http:
        paths:
          - path: /
            backend:
              serviceName: RELEASE-NAME-quality-control
              servicePort: http

但是在部署的时候，我得到一个错误。

Error: release quality-control failed: Deployment.apps "quality-control-frontend" is invalid: [spec.selector: Required value, spec.template.metadata.la                             bels: Invalid value: map[string]string{"app.kubernetes.io/instance":"quality-control", "app.kubernetes.io/name":"quality-control-frontend"}: `selector`                              does not match template `labels`]

Answer 1

在第一个部署对象中有一个缩进的问题。

改为

spec:
    replicas: 1
    selector:
    matchLabels:
      app.kubernetes.io/name: quality-control-frontend
      app.kubernetes.io/instance: RELEASE-NAME

到

spec:
    replicas: 1
    selector:
      matchLabels:
        app.kubernetes.io/name: quality-control-frontend
        app.kubernetes.io/instance: RELEASE-NAME

另外，服务列表也存在缩进的问题，需要将其从

- apiVersion: v1
    kind: Service
    metadata:
    name: quality-control-backend
    labels:
        app.kubernetes.io/name: quality-control-backend
        helm.sh/chart: quality-control-0.1.0
        app.kubernetes.io/instance: RELEASE-NAME}
        app.kubernetes.io/managed-by: Tiller

到

- apiVersion: v1
    kind: Service
    metadata:
      name: quality-control-backend
      labels:
        app.kubernetes.io/name: quality-control-backend
        helm.sh/chart: quality-control-0.1.0
        app.kubernetes.io/instance: RELEASE-NAME
        app.kubernetes.io/managed-by: Tiller
