Production

[jakobholmelund]

Hey

I'm currently getting my django app ready for production. I'm using docker, and i currently using the image grahamdumpleton/mod-wsgi-docker:python-2.7 from https://github.com/GrahamDumpleton/mod_wsgi-docker . I'm running it a bit customized as i am using the command ["python", "sonofatailorapp/manage_prod.py", "runmodwsgi", "config.wsgi", "--port=80", "--log-to-terminal", "--startup-log"] .

As far as i can understand, this method uses the mod_wsgi-express settings to run the server. And now is where it gets confusing to me. The docs says that mod_wsgi-express will automatically generate the settings as specified in the arguments, but i'm at a point where i would like to use other apache modules like mod_pagespeed and i can't seem to find a way doing this with mod_wsgi-express. I really like that i can startup the server through djangos manage.py as it set's up all the right paths for static files and so on. I also can't seem to find full documentation for mod_wsgi-express and maybe that's why i don't get it. At this point i'm not even sure if express is the right way to go in production. Any input would be greatly appreciated !

Cheers

The response

For all the users not wanting to login with a google account:

To get mod_pagespeed incorporated into the image and used will take a few steps which are going to be a little bit fiddly.

What the steps are exactly is going to depend a bit on whether you are using mod_wsgi-docker:python-2.7 or mod_wsgi-docker:python-2.7-onbuild. Which is used dictates how you trigger the download and building of mod_pagespeed into the image so it can be used. I will defer explaining that until you can tell me which Docker image you are using and what your Dockerfile looks like.

Also, hopefully all the compiler bits needed are already a part of the image. From memory mod_pagespeed is written in C++. I think I have g++ as part of the image.

Presuming mod_pagespeed is installed into the module directory of the Apache installation the image provides, then the next step is to incorporate that into the mod_wsgi-express configuration.

Since that is auto generated, what would need to be done is create a Apache configuration file snippet and tell mod_wsgi-express to include that at the end.

python sonofatailorapp/manage_prod.py runmodwsgi config.wsgi --port=80 --log-to-terminal --startup-log \
        —include-file pagespeed.conf

The pagespeed.conf file would then, at a guess, have something like:

    <IfVersion < 2.4>
      LoadModule pagespeed_module ${MOD_WSGI_MODULES_DIRECTORY}/mod_pagespeed.so
    </IfVersion>
    <IfVersion >= 2.4.2>
      LoadModule pagespeed_module ${MOD_WSGI_MODULES_DIRECTORY}/mod_pagespeed_ap24.so
    </IfVersion>

    ModPagespeed on

    AddOutputFilterByType MOD_PAGESPEED_OUTPUT_FILTER text/html

Let me know which Docker image you are using and your Dockerfile and I will see if I can work out the recipe to get it incorporated into a derived image.

I might be mistaken, sorry. But in any case, now we also have a backup.
