well first, don't listen to Alex, delete your dockerfile, redoploy, then give me your full build log please
full marten
@random whale Hello Brody, here is the full log:
random whale
looks like you are trying to use a windows specific package, services on railway generally use ubuntu
full marten
actually, i just noticed pywin32
full marten
looks like you are trying to use a windows specific package, services on railway...
i deleted this from requirements.txt
random whale
yep that would be the package in question
full marten
let me see if that work now
random whale
you may have pip freezed every package on your system into the requirements.txt file, please go through that file and delete all packages you don't use in your project
full marten
you may have pip freezed every package on your system into the requirements.txt ...
no i only freezed the one inside the virtual environment of my project
random whale
ah cool
random whale
more or less yeah
full marten
ah cool
ok, so how do i figure out the CNAME on railway?
cause i am gonna point the domain from cloudflare to railway deployment
random whale
do you own a domain?
full marten
yes.
random whale
who's your domain provider
full marten
cloudflare
random whale
perfect
then go to the service settings, add your custom domain, then railway will give you the cname address, use that in the cloudflare DNS settings
make sure you have set SSL/TLS mode to full in cloudflare too
full marten
i can't see any cname address in the settings, the domain is already set
random whale
you would have been given the cname when you added the domain
send me your custom domain please, along with a screenshot of the domains in the railway service, and your DNS settings in cloudflare
full marten
send me your custom domain please, along with a screenshot of the domains in the...
nvm, got it when i re-added the domain
random whale
all works?
full marten
let me see one last thing
full marten
all works?
I guess that part of "DNS takes 72 hours to propgate"?
random whale
do you see that from your custom domain?
full marten
yes.
random whale
then DNS has already propagated, that's an issue with your app
full marten
alright, let me see then
random whale
any errors in the deploy logs
full marten
any errors in the deploy logs
deployment logs
random whale
oh you definitely don't want to be running a development server on railway
full marten
oh snap
random whale
do you have a Procfile?
full marten
how did i not notice this, ok so, what the procedure here?
in the old times, i used to keep the server running using gunicorn+ niginx for load balancing
but I guess railway does handle the server running for me
full marten
you still need gunicorn
ok, let's speak in term of gunicorn, why do i need it?
i thought gunicorn whole idea is to keep a server running, no?
random whale
ok, let's speak in term of gunicorn, why do i need it?
@terse raven your expertise are required
(he's an extremely experienced python dev)
full marten
noice
terse raven
Oi!
full marten
thanks for help Brody 🙂
terse raven
Let me read and catch up
full marten
take your time
random whale
why gunicorn necessary
terse raven
Thanks. I’m caught up. Gunicorn isn’t a process manager, it is a whole production WSGI server. If you just run your manage.py file, it will launch the dev server which is for testing, and as you can see is looking at the wrong port.
With Gunicorn, it will not display error logs on the front end when people hit one, exposing not only your file structure, but also exposing a debug terminal in the browser allowing people to run exploitation code
random whale
whats more so the "what" and not the "why"
full marten
Thanks. I’m caught up. Gunicorn isn’t a process manager, it is a whole productio...
do you mind explaining how gunicorn handle running the server? I thought gunicorn somehow run on a local port too?
random whale
dev, no problems with wanting to understand it, but regardless if you understand or not, you still need gunicorn
terse raven
I would place a railway.json file in your project root and place the following contents in it
{
"$schema": "https://railway.app/railway.schema.json",
"build": {
"builder": "NIXPACKS"
},
"deploy": {
"startCommand": "python manage.py migrate && python manage.py collectstatic --noinput && gunicorn mysite.wsgi",
"restartPolicyType": "ON_FAILURE",
"restartPolicyMaxRetries": 10
}
}
You can also look at the template for how to configure your port
full marten
dev, no problems with wanting to understand it, but regardless if you understand...
yeah, i will create the procfile and add the gunicorn command, but i really want to understand why i need it for the future
random whale
you need it to run your app in a production environment, its as simple as that
full marten
I would place a railway.json file in your project root and place the following c...
Thanks, i will look it up
full marten
you need it to run your app in a production environment, its as simple as that
true, but what kind of address does gunicorn run in this case?
like in dev mode, i run 127.0.0.1 which is the local host
random whale
gunicorn runs on 0.0.0.0 and environment variable PORT by default
terse raven
gunicorn will listen on the PORT env variable
full marten
that true, but isnt that local address too?
or is 0.0.0.0 a different case?
terse raven
It’s not a loop back address like 127.0.0.1
0.0.0.0 binds to all network interfaces in a server environment
random whale
all ipv4* hehe
full marten
0.0.0.0 binds to all network interfaces in a server environment
just had a good read here:
https://www.howtogeek.com/225487/what-is-the-difference-between-127.0.0.1-and-0.0.0.0/
I guess 0.0.0.0 work as a placeholder address, which let all addresses access it
random whale
thats a good enough analogy
full marten
wtf is this embed tho 😭
terse raven
Discord being dumb
full marten
i will re-deploy and give you a feedback!
full marten

why is $schema a not allowed property in json?
random whale
dont worry about that
full marten
was busy for a while, i re-deployed, now i get too many redirects error
terse raven
Do you have your cloudflare ssl settings on “Full”
random whale
make sure you have set SSL/TLS mode to full in cloudflare too
remember when i said this lol
full marten
Do you have your cloudflare ssl settings on “Full”
let me check, but last time it was
terse raven
If it’s anything other than “Full”, it will not work
terse raven
No, don’t use strict
random whale
django may also be a culprit for too many redirects
terse raven
And you used the cname address provided by railway when you added the domain?
terse raven
Not the railway generated domain as the target, correct?
full marten
Not the railway generated domain as the target, correct?
yes
the one they gave me when i set my custom domain (it was a dialog box)
terse raven
Yes, that’s the one you should be using. Unfortunately I’m not on the computer for another 4 1/2 hours, so I can’t really help troubleshoot too much more
full marten
all good fam, thanks for your help 🙂 !
terse raven
Anytime
full marten
alright i fixed everything
i had set SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https') in settings.py for django, which fixed the redirect error.

You’re good. It’s solved
