docker - docker-compose.yml无效类型

Question

docker-compose.yml

version: '2.0'
services:
  asdf-db:
    container_name: asdf-db
    build: ./asdf/db
    ports:
      - 5435:5432 # expose ports - HOST:CONTAINER
    environment:
      - POSTGRES_USER=postgres
      - POSTGRES_PASSWORD=postgres
    healthcheck:
      test: exit 0

  asdf-service:
    container_name: asdf-service
    build: ./
    volumes:
      - '.:/usr/src/asdf'
    ports:
      - 5001:5000 # expose ports - HOST:CONTAINER
    environment:
      - APP_SETTINGS=asdf.config.DevelopmentConfig
      - DATABASE_URL=postgres://postgres:postgres@asdf-db:5432/asdf_dev
      - DATABASE_TEST_URL=postgres://postgres:postgres@asdf-db:5432/asdf_test
    depends_on:
      asdf-db:
        condition: service_healthy
      links:
        - asdf-db

当我运行 docker-compose up -d时，出现以下错误消息:

ERROR: The Compose file '.\docker-compose.yml' is invalid because:
Unsupported config option for services.asdf-db: 'healthcheck'
services.asdf-service.depends_on contains an invalid type, it should be an array

我尝试将版本切换到2.1，然后收到以下错误消息:

ERROR: The Compose file '.\docker-compose.yml' is invalid because:
services.asdf-service.depends_on.links contains ["asdf-db"], which is an invalid type, it should be an object

如何将asdf-db更改为对象？

Answer 1

Healthcheck已添加到2.1中，因此您至少需要该版本。

在2.1版本中，您在links中包含depends_on，而它应该处于同一级别。
