docker-compose 多网络私有(private)和互联网

Question

我需要我的容器(本地 grpc_alpine)在连接到内部网络时能够访问互联网。我尝试了以下 yaml 文件:

version: '2'
services:
  gr1:
    image: grpc_alpine
    hostname: gr1
    container_name: gr1
    privileged: true
    stdin_open: true
    tty: true
    volumes:
      - "${PWD}/assets/grpc:/etc/grpc"
    networks:
      - default
      - mynet:
          ipv4_address: "10.10.10.11"
    environment:
      - DEFAULT_GATEWAY=10.10.10.254


networks:

  mynet:
    ipam:
      config:
          - subnet: 10.10.10.0/24
            gateway: 10.10.10.254

但抛出这个问题:

compose.config.config.find: Using configuration files: ./docker-compose.yml ERROR: compose.cli.main.main: The Compose file './docker-compose.yml' is invalid because: services.gr1.networks contains {"mynet": {"ipv4_address": "10.10.10.11"}}, which is an invalid type, it should be a string

Answer 1

您的 yaml 配置存在一个小问题。 networks services 中的选项需要 map 而不是列表。试试这个:

version: '2'
services:
  gr1:
    image: grpc_alpine
    hostname: gr1
    container_name: gr1
    privileged: true
    stdin_open: true
    tty: true
    volumes:
      - "${PWD}/assets/grpc:/etc/grpc"
    networks:
      default:
      mynet:
        ipv4_address: "10.10.10.11"
    environment:
      - DEFAULT_GATEWAY=10.10.10.254

networks:
  mynet:
    ipam:
      config:
        - subnet: 10.10.10.0/24
          gateway: 10.10.10.254
