k8s .netcore webapi

.netcore webapi 迁移到到 k8s

1.  k create deployment aaa --image=aaa-image:1.2  -r=2,  然后把生成的 deploy, -oyaml, 删除不必要信息，保存为yaml

apiVersion: apps/v1

kind: Deployment

metadata:

  labels:

    app: my-app

  name: my-app

  namespace: app-ns

spec:

  replicas: 2

  selector:

    matchLabels:

      app: my-app

  template:

    metadata:

      labels:

        app: my-app

    spec:

      volumes:

        - name: app-json

          configMap:

            name: app-json

      containers:

      - image: my-app:1.2.0.188

              #- image: nexus-cn:443/mcr.microsoft.com/dotnet/aspnet:7.0

              #   command: [ "/bin/bash", "-c", "--" ]

              # args: [ "while true; do sleep 30; done;" ]

        imagePullPolicy: IfNotPresent

        name: fso-nms-vehicle

        terminationMessagePath: /dev/termination-log

        terminationMessagePolicy: File

        lifecycle:

          postStart:

            exec:

              command:

              - "/bin/sh"

              - "-c"

              - "cp /app2/app.json /app/appsettings.Int2.json"

        volumeMounts:

          - name: app-json

            mountPath: /app2

        env:

        - name: ASPNETCORE_ENVIRONMENT

          value: "Int2"

这里用到了 lifecycle， 但是这个不保证在应用执行之前执行。所以这样不合适

还要用 subpath.
