docker - kubernetes kompose up Unsupported env_file key

Question

我正在尝试将一个文档化的项目迁移到 kubernetes，我使用 Kompose 来转换项目
kompose --file docker-compose.yml convert ,

当我运行 kompose up迁移文件后
我得到这个错误
$ kompose up
WARN Unsupported env_file key - ignoring

FATA Error while deploying application: k.Transform failed: image key required within build parameters in order to build and push service 'drkiq'

.env 文件:
SECRET_TOKEN=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
WORKER_PROCESSES=1
LISTEN_ON=0.0.0.0:8000
DATABASE_URL=postgresql://drkiq:yourpassword@postgres:5432/drkiq?encoding=utf8&pool=5&timeout=5000
CACHE_URL=redis://redis:6379/0
JOB_WORKER_URL=redis://redis:6379/0

Dockerized项目链接here !

知道如何将 .env 文件转换为可与 kubernetes kompose 一起使用的格式

docker 撰写文件:

  postgres:
    image: postgres:9.4.5
    environment:
      POSTGRES_USER: drkiq
      POSTGRES_PASSWORD: yourpassword
    ports:
      - '5432:5432'
    volumes:
      - drkiq-postgres:/var/lib/postgresql/data

  redis:
    image: redis:3.0.5
    ports:
      - '6379:6379'
    volumes:
      - drkiq-redis:/var/lib/redis/data

  drkiq:
    build: .
    links:
      - postgres
      - redis
    volumes:
      - .:/drkiq
    ports:
      - '8000:8000'
    env_file:
      - .drkiq.env
  sidekiq:
    build: .
    command: bundle exec sidekiq -C config/sidekiq.yml
    links:
      - postgres
      - redis
    volumes:
      - .:/drkiq
    env_file:
      - .drkiq.env

Answer 1

Kubernetes kompose 支持 env_file从 Docker Compose 3.x 转换Conversion matrix 中描述的版本.

在 Kubernetes 中，您可以使用 ConfigMap存储来自 env_file 的环境变量.对于 SECRET_TOKEN变量，你可以使用 Secrets保存您的私有(private)和敏感数据。

您还可以检查其他工具以进行转换，例如 compose2kube或 k8s-env-gen .

根据附件Docker-composer文件和转换过程中的错误，我可以假设您错过了 drkiq 的图像键值和 sidekiq服务:

更新: docker-compose.yml 文件

version: '2'

services:
  postgres:
    image: postgres:9.4.5
    environment:
      POSTGRES_USER: drkiq
      POSTGRES_PASSWORD: yourpassword
    ports:
      - '5432:5432'
    volumes:
      - drkiq-postgres:/var/lib/postgresql/data

  redis:
    image: redis:3.0.5
    ports:
      - '6379:6379'
    volumes:
      - drkiq-redis:/var/lib/redis/data

  drkiq:
    build: .
    image: drkiq:tag
    links:
      - postgres
      - redis
    volumes:
      - .:/drkiq
    ports:
      - '8000:8000'
    env_file:
      - .drkiq.env
  sidekiq:
    build: .
    command: bundle exec sidekiq -C config/sidekiq.yml
    image: sidekiq:tag
    links:
      - postgres
      - redis
    volumes:
      - .:/drkiq
    env_file:
      - .drkiq.env
