码头与pycharm 5 [英] docker with pycharm 5

问题描述

我试图为我们的django应用程序构建一个基于docker的开发框。它的运行顺利。

我的团队成员都不会关心，直到有一个很好的IDE集成，所以我玩新的和闪亮的

我也尝试过像这样的纯python conf：

这就像大混蛋，因为它再次尝试通过数据库链接进行连接，即使我删除它从

调试的下一步是什么？

奖金问题：pyCharm在项目设置中识别已安装的软件包，但是在代码中找不到它，为什么？

更新

我发现pyCharm正在为自己启动容器，并且不使用现有的docker容器。因此，看起来pycharm只能使用单个容器，这根本似乎没有什么用。

解决方案

它事实证明，pycharm 5每个项目只支持一个容器。基本上，这意味着Docker支持在pyCharm 5中是无用的。

I try to build a docker-based development box for our django app. It's running smoothly.

None of my teammembers will care about that until there is a nice IDE integration, therefore I play the new and shiny Docker Support in pycharm 5.

I followed the linked documentation and pycharm does recognise my web container and it's python interpreter.

Here's my docker-compose.yml:

web:
  build: .
  ports:
    - "8000:8000"
  volumes:
    - .:/srv/app
  links:
    - database
    - search
    - cache
  entrypoint: /home/deployer/web-entrypoint.sh


worker:
  build: .
  volumes:
    - .:/srv/app
  command: celery -A core worker -l info
  links:
    - database
    - search
    - cache

database:
  image: postgres:latest
  volumes_from:
    - data
  environment:
    - POSTGRES_USER=app_user
    - POSTGRES_PASSWORD=app_password

data:
  image: busybox
  volumes:
    - /var/lib/postgresql/data

search:
  image: "elasticsearch:1.7"
  command: "elasticsearch --http.bind_host=0.0.0.0"
  ports:
    - "9200:9200"

cache:
  image: "redis:latest"
  ports:
    - "6379"

Unfortunately there is no docker-compose support in pycharm, that's why djangos runserver failed upon connecting to the database. Therefore I copied the (fortunately predictable) aliases from the web container's /etc/host:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'app_db',
        'USER': 'app_user',
        'PASSWORD': 'app_password',
        'HOST': 'docker_database_1',
        'PORT': '5432',
    }
}

HAYSTACK_CONNECTIONS = {
    'default': {
        'ENGINE': 'haystack.backends.elasticsearch_backend.ElasticsearchSearchEngine',
        'URL': 'http://docker_search_1:9200/',
        'INDEX_NAME': 'app',
    },
}

BROKER_URL = 'redis://docker_cache_1:6379/0'
CELERY_RESULT_BACKEND = BROKER_URL

Now the database connection error is no longer there, but the output of my django server gives me this:

a6993f56e61e:python -u /opt/project/manage.py runserver docker:8001 --traceback
Performing system checks...

System check identified no issues (0 silenced).

Django version 1.8.6, using settings 'core.settings.dev'
Starting development server at http://docker:8001/
Quit the server with CONTROL-C.
Error: [Errno -2] Name or service not known

Process finished with exit code 1

No stack trace, just this.

What's strange: python -u /opt/project/manage.py - what's this? The folder does not exist on both host and the container.

My Django Server conf:

I tried as well a pure-python conf like this:

This is like mega-confusing because it tries again to connect via the "database" link, even if I remove it from the settings at all.

What would be the next steps for debugging?

Bonus question: pyCharm does recognize the installed packages in the project settings, but it can't find it in the code, why?

UPDATE

I found out that pyCharm is starting the container for itself and is not using the existing docker container. Hence it looks like pyCharm can only work with a single container, which does not seem to be that useful at all.

解决方案

It turns out that pycharm 5 supports only one container per project. Basically that translates to "Docker support is useless in pyCharm 5".

Multi-container management on top of docker compose is requested here and is awaiting YOUR upvote:
