docker-compose给出错误：无法找到指定的Dockerfile：Dockerfile [英] docker-compose gives ERROR: Cannot locate specified Dockerfile: Dockerfile
问题描述
我克隆了一个使用docker-compose的docker设置。一位远程开发人员确认它可以正常工作，所以我的问题似乎出在我的设置上。
I've cloned a docker setup which uses docker-compose. One remote developer confirms it works so my problem seems to be with my setup.
我运行了 docker-compose up ，但是目前这给了我：
I ran docker-compose up, but that currently gives me this:
$ docker-compose up
Creating volume "mycompanydocker_mysql-data" with local driver
Creating volume "mycompanydocker_redis-data" with local driver
Creating volume "mycompanydocker_app-data" with local driver
Creating volume "mycompanydocker_mongo-data" with local driver
mycompanydocker_redis_1 is up-to-date
mycompanydocker_mongo_1 is up-to-date
mycompanydocker_mysql_1 is up-to-date
Building app
ERROR: Cannot locate specified Dockerfile: Dockerfile
我的 docker-compose.yml 看起来像这样：
version: '2'
services:
mysql:
build: mysql/.
env_file: env
expose:
- 3306
ports:
- "3306:3306"
volumes:
- mysql-data:/var/lib/mysql
mongo:
build: mongo/.
env_file: env
expose:
- 27017
ports:
- "27017:27017"
volumes:
- mongo-data:/data/db
redis:
build: redis/.
env_file: env
expose:
- 6379
ports:
- "6379:6379"
volumes:
- redis-data:/data
app:
build: app/.
env_file: env
expose:
- 80
ports:
- "80:80"
volumes:
# To mount a local directory, change this
# To use a docker volume
- app-data:/app
# local app
# - ./mycompany:/app
depends_on:
- mysql
- mongo
- redis
volumes:
app-data:
driver: local
mysql-data:
driver: local
redis-data:
driver: local
mongo-data:
driver: local
，树看起来像这样：

我不了解的是 docker-compose 似乎找到了所有 Dockerfile s，但 app 文件夹中的那个除外。我在OSX 10.11.2上安装了以下软件：
The thing I don't understand is that docker-compose seems to find all Dockerfiles, except for the one in the app folder. I've got the following installed on OSX 10.11.2:
-
Docker版本1.10.3，内部版本20f81dd -
docker-compose版本1.6.2，构建4d72027
Docker version 1.10.3, build 20f81dddocker-compose version 1.6.2, build 4d72027
我刚开始使用Docker，有点卡在这里。有人知道什么可能是错误的，或者我该如何调试呢？欢迎所有提示！
I'm just starting out with Docker and I'm kinda stuck here. Does anybody know what could possibly be wrong or how I can debug this? All tips are welcome!
我忘了提到没有隐藏的 .dockerignore 文件：
$ ls -la
total 56
drwx------@ 11 kramer staff 374 25 mrt 14:13 .
drwx------+ 1134 kramer staff 38556 26 mrt 17:27 ..
-rw-r--r--@ 1 kramer staff 8196 26 mrt 08:14 .DS_Store
-rw-r--r--@ 1 kramer staff 23 24 mrt 15:29 .gitignore
-rw-r--r--@ 1 kramer staff 3879 24 mrt 15:29 README.rst
drwxr-xr-x@ 7 kramer staff 238 25 mrt 14:26 app
-rw-r--r--@ 1 kramer staff 868 25 mrt 17:50 docker-compose.yml
-rw-r--r--@ 1 kramer staff 219 24 mrt 15:29 env
drwxr-xr-x@ 3 kramer staff 102 24 mrt 15:29 mongo
drwxr-xr-x@ 3 kramer staff 102 24 mrt 15:29 mysql
drwxr-xr-x@ 3 kramer staff 102 24 mrt 15:29 redis
和 .gitignore 文件也不包含任何特殊内容（不知道是否重要）：
and the .gitignore file doesn't contain anything special either (don't know if it matters):
$ cat .gitignore
.project
.pydevproject
推荐答案
以下是指定dockerfile的方法。抱歉，我无法在注释中执行此操作，因为那里不支持格式化。
Here is how to specify dockerfile. Sorry I cannot do it in comments as formatting is not supported over there.
https://docs.docker.com/compose/compose-file/#context
app:
build:
context: app
dockerfile: Dockerfile
