gunicorn 在使用 docker-compose run 而不是 docker-compose up 调用时可以工作

Question

我正在尝试在 docker-compose 中启动烧瓶应用程序。当我按如下方式运行它时：

docker-compose run web /usr/local/bin/gunicorn restml.app:app -b :8000

gunicorn 开始正常，但是当我将以下行添加到 docker-compose.yml 时

command: /usr/local/bin/gunicorn restml.app:app -b :8000 --error-logfile - --log-level DEBUG

我明白了

web_1    | Traceback (most recent call last):
web_1    |   File "/usr/local/lib/python3.5/site-packages/gunicorn/arbiter.py", line 557, in spawn_worker
web_1    |     worker.init_process()
web_1    |   File "/usr/local/lib/python3.5/site-packages/gunicorn/workers/base.py", line 126, in init_process
web_1    |     self.load_wsgi()
web_1    |   File "/usr/local/lib/python3.5/site-packages/gunicorn/workers/base.py", line 136, in load_wsgi
web_1    |     self.wsgi = self.app.wsgi()
web_1    |   File "/usr/local/lib/python3.5/site-packages/gunicorn/app/base.py", line 67, in wsgi
web_1    |     self.callable = self.load()
web_1    |   File "/usr/local/lib/python3.5/site-packages/gunicorn/app/wsgiapp.py", line 65, in load
web_1    |     return self.load_wsgiapp()
web_1    |   File "/usr/local/lib/python3.5/site-packages/gunicorn/app/wsgiapp.py", line 52, in load_wsgiapp
web_1    |     return util.import_app(self.app_uri)
web_1    |   File "/usr/local/lib/python3.5/site-packages/gunicorn/util.py", line 357, in import_app
web_1    |     __import__(module)
web_1    | ImportError: No module named 'restml'

文件结构为：

web
|-> Dockerfile
|-> requirements.txt
\-> restml
    \->app.py

我的app.py 是

from flask import Flask

app = Flask(__name__)


@app.route('/')
def index():
    return 'Index Page'


@app.route('/hello')
def hello():
    return 'Hello, World'

if __name__ == '__main__':
    app.run()

我的docker-compose.yml 的web 条目是

web:
  build: ./web
  expose:
    - "8000"
  volumes:
    - /usr/src/app/
  env_file: .env
  environment:
     FLASK_DEBUG: 'true'
  command: /usr/local/bin/gunicorn restml.app:app -b :8000 --error-logfile - --log-level DEBUG

当我这样做时

docker-compose run web

我明白了

[2016-10-20 17:20:22 +0000] [1] [INFO] Starting gunicorn 19.6.0
[2016-10-20 17:20:22 +0000] [1] [DEBUG] Arbiter booted
[2016-10-20 17:20:22 +0000] [1] [INFO] Listening at: http://0.0.0.0:8000 (1)

[2016-10-20 17:20:22 +0000] [1] [DEBUG] 1 workers

所以它似乎比其他任何东西都更与docker-compose 相关。

谁能解释一下我该如何解决这个问题？

附加信息

当我运行docker-compose run web ls 时，我明白了，

Dockerfile  requirements.txt  restml

当我运行docker-compose run web ls restml 时，我明白了，

app.py

所有文件都是模式 0644 和文件 0755。

一些死容器仍在后台运行。我删除了所有这些重新启动，现在一切正常。

我删除了它们，

docker ps --all |  grep restml | cut -c138- | xargs docker rm
