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

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

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-compose版本是

也尝试过

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

最佳答案

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
