docker - 错误 : In file './docker-compose.yml' , 服务 'volumes' 必须是映射而不是数组

Question

我的 docker-compose.yml 如下所示，我正在尝试遵循 docker 注册表文档 here 中的 compose 文件.当我运行 docker-compose up 时，出现以下错误。

ERROR: In file './docker-compose.yml', service 'volumes' must be a mapping not an array.

registry:
  restart: always
  image: sudarshan/registry
  ports:
    - 5000:5000
environment:
  REGISTRY_HTTP_TLS_CERTIFICATE: /certs/domain.crt
  REGISTRY_HTTP_TLS_KEY: /certs/domain.key
  REGISTRY_AUTH: silly
  REGISTRY_AUTH_SILLY_SERVICE: SILLY_SERVICE
  REGISTRY_AUTH_SILLY_REALM: SILLY_REALM
volumes:
  - /usr/certs:/certs

我的 docker 版本是

Docker version 1.12.1, build 23cf638

docker-compose 版本是

docker-compose version 1.7.1, build 0a9ab35

在 Ubuntu 16.04 上运行

也试过了

registry:
  restart: always
  image: sudarshan/registry
  ports:
    - 5000:5000
environment:
  REGISTRY_HTTP_TLS_CERTIFICATE: /certs/domain.crt
  REGISTRY_HTTP_TLS_KEY: /certs/domain.key
  REGISTRY_AUTH: silly
  REGISTRY_AUTH_SILLY_SERVICE: SILLY_SERVICE
  REGISTRY_AUTH_SILLY_REALM: SILLY_REALM
volumes:
    - /usr/certs:/certs

问题是您没有正确缩进字段。您的 docker-compose 应该如下所示:

registry:
  restart: always
  image: sudarshan/registry
  ports:
    - 5000:5000
  environment:
    REGISTRY_HTTP_TLS_CERTIFICATE: /certs/domain.crt
    REGISTRY_HTTP_TLS_KEY: /certs/domain.key
    REGISTRY_AUTH: silly
    REGISTRY_AUTH_SILLY_SERVICE: SILLY_SERVICE
    REGISTRY_AUTH_SILLY_REALM: SILLY_REALM
  volumes:
    - /usr/certs:/certs
