我正在尝试使用来自Docker的uWSGI提供Django应用程序。我正在使用supervisor在Dockerfile的末尾为我启动该过程。当我运行该镜像时,它表示uWSGI进程已启动并成功,但是我无法以我认为会显示它的URL来查看该应用程序。也许我没有正确设置/配置东西?
我现在没有监督nginx的启动,因为我当前正在通过Amazon S3提供静态文件,并且想要首先专注于启动和运行wsgi。
我通过执行uwsgi --init uwsgi.ini:local
在本地使用uwsgi成功运行了应用程序,但是将其移至docker时遇到了麻烦。
这是我的Dockerfile

RUN pip install -r /home/docker/code/app/requirements.txt
EXPOSE 8080
CMD ["supervisord", "-c", "/home/docker/code/supervisor-app.conf", "-n"]
这是我的uwsgi.ini
[uwsgi]
# this config will be loaded if nothing specific is specified
# load base config from below
ini = :base
# %d is the dir this configuration file is in
socket = %dmy_app.sock
master = true
processes = 4
[dev]
ini = :base
# socket (uwsgi) is not the same as http, nor http-socket
socket = :8001
[local]
ini = :base
http = :8000
# set the virtual env to use
home=/Users/my_user/.virtualenvs/my_env
[base]
# chdir to the folder of this config file, plus app/website
chdir = %dmy_app/
# load the module from wsgi.py, it is a python path from
# the directory above.
module=my_app.wsgi:application
# allow anyone to connect to the socket. This is very permissive
chmod-socket=666
http = :8080
这是我的supervisor-app.conf文件
[program:app-uwsgi]
command = /usr/local/bin/uwsgi --ini /home/docker/code/uwsgi.ini
从使用boot2docker的MAC,我试图通过$(boot2docker ip):8080访问该应用程序
最终,我希望将此容器上载到AWS Elastic Beanstalk,不仅要运行uWSGI进程,还要运行一个celery worker。
运行容器时,从日志中可以看到主管和uwsgi均已成功启动。我既可以单独使用uwsgi,也可以通过主管使用uwsgi使其在本地计算机上运行,但是由于某种原因,当我将其容器化时,在任何地方都找不到它。
这是我启动Docker容器时记录的内容
2014-12-25 15:08:03,950 CRIT Supervisor running as root (no user in config file)
2014-12-25 15:08:03,953 INFO supervisord started with pid 1

最佳答案
您如何启动Docker容器?
我看不到任何CMD或ENTRYPOINT脚本,因此不清楚如何开始。
通常,除非绝对必要,否则我建议避免使用supervisor之类的方法,只需从CMD行在前台启动uWSGI。尝试将以下内容添加到Dockerfile的最后一行:
CMD ["/usr/local/bin/uwsgi", "--ini", "/home/docker/code/uwsgi.ini"]
然后使用
docker run -p 8000:8000 image_name
运行。您应该从uWSGI得到一些答复。如果可行,我建议您将其他服务(postgres,node,移至单独的容器)。有Node,Python和Postgres的官方图片,可以为您节省一些时间。请记住,Docker容器只在其主进程上运行(该进程必须在前台运行)。
