在远程主机上的Docker flask uwsgi 404
更新2
我configuration我的路由在从create_app调用的configure_blueprints。 我不想把所有的视图处理程序放在uwsgi.py中。 它们存储在单独的模块中。
def configure_blueprints(app): from .root import root_bp ... blueprints = [ (root_bp, None), ... ] for bp, endpoint in blueprints: app.register_blueprint(bp, url_prefix=endpoint) return app def create_app(config_fn=None): app = Flask(__name__, template_folder='../templates', static_folder='../static') ... configure_blueprints(app) return app 应用程序/根/ views.py
root_bp = Blueprint('root_bp', __name__) @root_bp.route('/') def root(): if not current_user.is_authenticated: return redirect('/login/') return render_template('index.html')
这里是SIMPLE_SETTINGS=app.config,instance.docker python3 manage.py list_routes输出SIMPLE_SETTINGS=app.config,instance.docker python3 manage.py list_routes
2017-03-01 06:48:11,381 - passlib.registry - DEBUG - registered 'sha512_crypt' handler: <class 'passlib.handlers.sha2_crypt.sha512_crypt'> ... root_bp.root HEAD,OPTIONS,GET / ...
这是list_routes命令的实现
@manager.command def list_routes(): import urllib output = [] for rule in flask.current_app.url_map.iter_rules(): options = {} for arg in rule.arguments: options[arg] = '[{0}]'.format(arg) methods = ','.join(rule.methods) try: url = flask.url_for(rule.endpoint, **options) except BaseException as e: print('Exc={}'.format(e)) line = urllib.parse.unquote('{:50s} {:20s} {}'.format(rule.endpoint, methods, url)) output.append(line) for line in sorted(output): print(line)
我不明白为什么路由应该放置到一个文件，不能dynamicconfiguration。 如果这不起作用，我该怎么办？
更新
uwsgi.ini
[uwsgi] env = SIMPLE_SETTINGS=app.config,instance.docker callable = app wsgi-file = /var/www/app/uwsgi.py uid = www-data gid = www-data socket = /var/www/app/uwsgi.sock chmod-socket = 666 logto = /var/log/uwsgi/app/app.log chdir = /var/www/app plugin = python3 master = true processes = 1
/var/www/app/uwsgi.py
from app import create_app app = create_app()
我在create_app函数里面configuration蓝图。 我想他们应该在申请开始的时候可用。 另外我使用Flask脚本。
SIMPLE_SETTINGS=app.config,instance.docker python3 manage.py shell
该shell启动没有错误。

我已经研究了所有相关的问题。 我无法解决我的问题。 我通过远程主机上的docker-machine部署我的项目。 这是我的configuration：
Dockerfile

如果您需要任何其他信息，请让我知道。 我尝试了不同的configuration：nginx-proxy image，gunicorn等。我和远程主机有同样的问题。 我还缺less什么？
我花了很多时间，不能用uwsgi socket解决问题。 我决定切换到gunicorn的 HTTP uwsgi Web服务器。 我喜欢安装的简单。

最后一个警告。 我使用了一个小小的修改docker的瓶子片段 。
class ReverseProxied(ProxyFix): def __init__(self, app, config, **kwargs): self.config = config super().__init__(app, **kwargs) def __call__(self, environ, start_response): script_name = environ.get('HTTP_X_SCRIPT_NAME', '') if script_name: environ['SCRIPT_NAME'] = script_name path_info = environ['PATH_INFO'] if path_info.startswith(script_name): environ['PATH_INFO'] = path_info[len(script_name):] scheme = environ.get('HTTP_X_SCHEME', '') if scheme: environ['wsgi.url_scheme'] = scheme # fix for docker to proxy server_name server_name = self.config.get('SERVER_NAME') if server_name: environ['HTTP_X_FORWARDED_HOST'] = server_name return super().__call__(environ, start_response) ... app.wsgi_app = ReverseProxied(app.wsgi_app, app.config)
应用程序/ config.py
SERVER_NAME = 'localhost:8000'
实例/ prod.py
SERVER_NAME = 'your-domain'
现在一切正常。
