无法使用 docker-compose 挂载文件

Unable to mount a file with docker-compose

I 运行 docker-compose -f docker-compose.prod.yml up 我立即得到错误:

ERROR: for frontend  Cannot start service frontend: OCI runtime create failed: container_linux.go:348: starting container process caused "process_linux.go:402: container init caused \"rootfs_linux.go:58: mounting \\"/c/Users/James/Projects/mysite/frontend/conf/nginx/mysite.template\\" to rootfs \\"/var/lib/docker/aufs/mnt/e7a2a699ae3e9ede0dd60b7cfdebb7f2d3adf71e8175157f3c9e88d3285796d2\\" at \\"/var/lib/docker/aufs/mnt/e7a2a699ae3e9ede0dd60b7cfdebb7f2d3adf71e8175157f3c9e88d3285796d2/etc/nginx/conf.d/default.conf\\" caused \\"not a directory\\"\"": unknown: Are you trying to mount a directory onto a file (or vice-versa)? Check if the specified host path exists and is the expected type

我的 mysite.template 文件存在。我正在使用 docker-machine 的数字海洋。在开发中,我没有在同一个 OS (ubuntu 16) 上遇到这个问题 运行ning。我在 windows 上使用 docker 工具箱进行开发。

这是来自 docker-compose.prod.yml 的前端配置:

frontend:
image: nginx:stable-alpine
restart: always
networks:
  - web
  - default
volumes:
  - ${PWD}/frontend/conf/nginx/mysite.template:/etc/nginx/conf.d/default.conf
  - ${PWD}/frontend/public:/var/www/html
labels:
  - "traefik.enable=true"
  - "traefik.basic.frontend.rule=Host:mysite.com"
  - "traefik.basic.port=80"

我遵循了 docs 的说明。知道出了什么问题吗?

您只能将主机目录作为卷装载,而不是 Docker 中的单个文件。

在您的 volumes 定义中,而不是: - ${PWD}/frontend/conf/nginx/mysite.template:/etc/nginx/conf.d/default.conf

你应该这样做: - ${PWD}/frontend/conf/nginx:/etc/nginx/conf.d
