Django apps not responding anymore... | Railway | Page 1

Hello all! I realized after the latest updates on railway (I don't know if it's related) but I noticed when I deploy my django apps, I see an error Application failed to respond
but nothing on my logs. This is the third time I have this issue and when I deploy the same app in a regular VPS on Digitalocean it turns out fine. What's going on?

Hello?

Could you perhaps post some logs from the build/deployment process? I know you said nothing on your logs, but I assume you were talking about the logs from the app.

rigid bane I only see this: [2023-07-31 00:08:10 +0000] [1] [INFO] Starting gunicorn 21.2....

Can you show me your start command please?

Here is my entire Dockerfile:

FROM python:3.10.8-slim-buster

WORKDIR /usr/src/app

ENV PYTHONDONTWRITEBYTECODE 1
ENV PYTHONUNBUFFERED 1

RUN pip install --upgrade pip
COPY ./requirements.txt /usr/src/app

#

rigid bane Here is my entire Dockerfile: FROM python:3.10.8-slim-buster WORKDIR /usr/src/...

Since you are listening on port 8000, in your service on the railway dashboard, set an environment variable of PORT and set it to 8000

#

That should solve it for you

#

Because the railway container injects a port variable for you that’s random, it won’t always line up with what you expose from your app

fickle rock Jul 31, 2023, 10:02 PM

#

use this please

#

what database type are you using? postgres?

rigid bane Jul 31, 2023, 10:02 PM

#

yes

fickle rock Jul 31, 2023, 10:03 PM

#

one sec

#

okay you are set, please use that dockerfile

frosty wyvern Jul 31, 2023, 10:04 PM

#

If you use Brody’s dockerfile, don’t set the environment variable in your service

fickle rock Jul 31, 2023, 10:05 PM

#

always use my dockerfiles 🙂

frosty wyvern Jul 31, 2023, 10:05 PM

#

fickle rock always use my dockerfiles 🙂

Hush! 🤣🤣

rigid bane Jul 31, 2023, 10:06 PM

#

hooold on now hahaha; I set the PORT var, I'll try if it works, if it doesn't I'll use Brody's one 😄

fickle rock Jul 31, 2023, 10:06 PM

#

please use mine anyway

rigid bane Jul 31, 2023, 10:07 PM

#

hahah, ok now I have ERR_TOO_MANY_REDIRECTS

https://docs.railway.app/deploy/exposing-your-app#provider-specific-instructions

rigid bane Jul 31, 2023, 10:07 PM

#

I have the exact same Dockerfile deployed on DO and with no problems

fickle rock Jul 31, 2023, 10:08 PM

#

please use my dockerfile, you should not be running createsuperuser from the dockerfile

frosty wyvern Jul 31, 2023, 10:08 PM

#

fickle rock please use my dockerfile, you should not be running createsuperuser from the doc...

Yeah, this is a bad idea

rigid bane Jul 31, 2023, 10:09 PM

#

I was just about to ask why did you remove the createsuperuser, I just did it because I created a new DB on railway and I wanted to directly start using the app for testing purposes only

frosty wyvern Jul 31, 2023, 10:10 PM

#

Every time you deploy, it will run that code

rigid bane Jul 31, 2023, 10:10 PM

#

yes but it will do it only if the user does not exist

frosty wyvern Jul 31, 2023, 10:10 PM

#

You would want to use the CLI, and link the service and run the command that way

rigid bane Jul 31, 2023, 10:10 PM

#

but anyways, I removed it, now I'm waiting for the autodeployment

frosty wyvern Jul 31, 2023, 10:10 PM

#

And if it fails to create the user, the deploy will fail, normally

fickle rock Jul 31, 2023, 10:10 PM

#

are you using cloudflare

rigid bane Jul 31, 2023, 10:11 PM

#

yes, and I have 2 environments on railway: production (nafssi.ma) and development (dev.nafssi.ma)

#

I added the 2 CNAMEs with and without proxy, both of them don't work

#

which is weird because I launched a little AI product called debuggr.net last year and it's on railway and built with django and it works just fine

#

you can try it it's fun 😄

#

The difference between debuggr.net and nafssi.ma is that with debuggr, I use the CNAME to point to the generated railway.app link I have, but with nafssi.ma, I used the CNAME value that railway.app provided me when I added the custom domain.

#

frosty wyvern Jul 31, 2023, 10:16 PM

#

Are your SSL settings set to Full?

rigid bane Jul 31, 2023, 10:18 PM

#

I just set them to Full now as per the railway doc

#

but in the debuggr.net project it's set to flexible and it works

#

ok I think I made some progress, I ditched the domain names railway provided me with and I replaced the records by the generated railway domains, set them to proxy, and set the SSL mode to full

#

now it gives me a 500 Error

#

so I'm getting close

frosty wyvern Jul 31, 2023, 10:21 PM

#

Are you using your dockerfile still or Brody’s?

rigid bane Jul 31, 2023, 10:21 PM

#

no Bordy's

frosty wyvern Jul 31, 2023, 10:22 PM

#

Okay. Cool. Do you still have the PORT environment variable set?

rigid bane Jul 31, 2023, 10:22 PM

#

the thing is, I have set DEBUG to True, I have Error 500, and nothing on the logs

#

no I removed the PORT var

frosty wyvern Jul 31, 2023, 10:22 PM

#

Hmmm

#

Shouldn’t be giving trouble at this point… are you able to share the repo? I could look at it in about an hour or so when I get back on my computer

rigid bane Jul 31, 2023, 10:27 PM

#

give me ur email

frosty wyvern Jul 31, 2023, 10:29 PM

#

GitHub username is vfehring

rigid bane Jul 31, 2023, 10:32 PM

#

done

frosty wyvern Jul 31, 2023, 10:32 PM

#

Cool. I’ll look at it in a bit, and see if we can resolve this for you

rigid bane Jul 31, 2023, 10:39 PM

#

Thank you so much! I think if we find the solution, it's gonna be the same for the other projects I have the same issue with (2 other django apps with the exact same issue...)

#

are you guys django developers as well?

frosty wyvern Jul 31, 2023, 10:40 PM

#

I am

#

Well, Django and flask

rigid bane Jul 31, 2023, 10:42 PM

#

Great, I'm a Fractional CTO and I am a Django, Flask and FastAPI dev 😄

#

It's nice to meet you!

frosty wyvern Jul 31, 2023, 10:43 PM

#

Nice! I love Python. I do a lot more than just Python, but it’s one of my favorites

rigid bane Jul 31, 2023, 10:43 PM

#

Me too! I went from Java to Python in 2014

#

Never went back 😄

#

Where are you from Vin?

frosty wyvern Jul 31, 2023, 10:44 PM

#

Houston

rigid bane Jul 31, 2023, 11:50 PM

#

Great

#

I'm from Morocco

#

Casablanca to be exact

frosty wyvern Jul 31, 2023, 11:52 PM

#

Very nice. I have a friend over there

rigid bane Aug 1, 2023, 1:26 AM

#

Very good!

#

And I have a friend in Houston too 😄 an old college roomate who works in AWS now

rigid bane Aug 1, 2023, 11:13 PM

#

any luck?

frosty wyvern Aug 1, 2023, 11:13 PM

#

Haven’t had a chance to look at it. Moved my computer and had a full system meltdown. Will be looking at it tonight for sure
