Re: Structure for deploying django channels in producting in AWS

Hi Vaisagh,

You do not need nginx/apache in front of daphne to make it work (though it
is usually a good idea to have it to serve static images, like you would
with gunicorn).

Have you tried connecting to the container directly locally from the host
machine or from inside the container itself? Have you tried swapping in
another container with something else on port 8000 to see if that works?
This sounds like a networking issue that's not really specific to Daphne.

Structure for deploying django channels in producting in AWS

2016-11-27 Thread Vaisagh Viswanathan 
Hi,

I'm trying to setup up my django project to use django channels in a 
dockerized setup. The whole setup seems to work fine on a local server and 
when I use runserver instead of daphne.  When I run the setup using daphne, 
the web page gives no response 

The  page isn’t working

* didn’t send any data.

ERR_EMPTY_RESPONSE


I am not sure at what point this is really failing. I tried running daphne 
with verbosity 2 and it seems the connections are not reaching it. 

The setup is like this:

I am running the whole set up on AWS. I have a Redis cluster that I am 
connecting to and using as a channel layer. I assume this is working fine, 
since the runserver seems to be working.

Following this I changed the setup to have two docker containers. The first 
one runs this script and has port 8000 of container mapped to port 80 of 
host machine:

cd myproject
python manage.py collectstatic --no-input
python manage.py migrate
python manage.py createsu
daphne myproject.asgi:channel_layer -b 0.0.0.0 -p 8000 --verbosity 2

The second container simply has this:

cd myproject  
python manage.py runworker


The logs from both containers indicate that they are both waiting for some 
requests to reach them. But nothing seems to be reaching them.

I have no idea what I'm supposed to be fixing here. DO i need to put 
nginx/apache in front of it for daphne to work??

Regards,
Vaisagh
