如何将docker-compose转换为kubernetes？

Question

我有一个使用nginx，php-fpm，mysql的示例项目： https://gitlab.com/x-team-blog/docker-compose-php

这是docker-compose文件：

subscribeNotification()
    .subscribe(onSuccess: { info in
        queryNotification()
            .flatMap({ notification in 
                return getNotificationAttributes(uid: notification.uid, attributes: [.appIdentifier, .content])
            })
            .flatMap({ notifAttrs
                return getAppAttributes(appIdentifier: notifAttrs.appIdentifier, attributes: [.displayName])
            })
            .subscribe {
                // have all the result from last two calls
            }
       })

我想在Google Cloud中使用Kubernetes，为此，我创建了几个文件：

永久卷数据库-claim0-persistentvolumeclaim.yaml：

version: '3'

services:
  php-fpm:
    build:
      context: ./php-fpm
    volumes:
      - ../src:/var/www

  nginx:
    build:
      context: ./nginx
    volumes:
      - ../src:/var/www
      - ./nginx/nginx.conf:/etc/nginx/nginx.conf
      - ./nginx/sites/:/etc/nginx/sites-available
      - ./nginx/conf.d/:/etc/nginx/conf.d
    depends_on:
      - php-fpm
    ports:
      - "80:80"
      - "443:443"

  database:
    build:
      context: ./database
    environment:
      - MYSQL_DATABASE=mydb
      - MYSQL_USER=myuser
      - MYSQL_PASSWORD=secret
      - MYSQL_ROOT_PASSWORD=docker
    volumes:
      - ./database/data.sql:/docker-entrypoint-initdb.d/data.sql

我还创建了秘密：

kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: database-claim0
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 400Mi

然后我创建了一个服务：

kubectl create secret generic mysql --from-literal=MYSQL_DATABASE=mydb --from-literal=MYSQL_PASSWORD=secret --from-literal=MYSQL_ROOT_PASSWORD=docker --from-literal=MYSQL_USER=myuser

现在我想创建database-deployment.yaml，但是我不知道我在docker-compose之类的复制sql文件的volumeMounts部分中必须写什么：

apiVersion: v1
kind: Service
metadata:
  name: database
  labels:
    app: database
spec:
  type: ClusterIP
  ports:
    - port: 3306
  selector:
    app: database

database-deployment.yaml

- ./database/data.sql:/docker-entrypoint-initdb.d/data.sql

UPD： 我的错。我没有先推送图片。

使用kompose

INFO Kubernetes file "nginx-service.yaml" created
INFO Kubernetes file "database-deployment.yaml" created
INFO Kubernetes file "database-claim0-persistentvolumeclaim.yaml" created
INFO Kubernetes file "nginx-deployment.yaml" created
INFO Kubernetes file "nginx-claim0-persistentvolumeclaim.yaml" created
INFO Kubernetes file "nginx-claim1-persistentvolumeclaim.yaml" created
INFO Kubernetes file "nginx-claim2-persistentvolumeclaim.yaml" created
INFO Kubernetes file "nginx-claim3-persistentvolumeclaim.yaml" created
INFO Kubernetes file "php-fpm-deployment.yaml" created
INFO Kubernetes file "php-fpm-claim0-persistentvolumeclaim.yaml" created
