Deploying for the first time

Hi, I am new to railroad and I am trying to deploy my flask app.

I am getting this error:

Dockerfile:24

-------------------

22 |     # build phase

23 |     COPY . /app/.

24 | >>> RUN  npm install --prefix react-app && npm run build --prefix react-app && pip install -r requirements.txt && pip install psycopg2 && flask db upgrade && flask seed all

25 |

-------------------

ERROR: failed to solve: process "/bin/bash -ol pipefail -c npm install --prefix react-app && npm run build --prefix react-app && pip install -r requirements.txt && pip install psycopg2 && flask db upgrade && flask seed all" did not complete successfully: exit code: 127

 

Error: Docker build failed

In the attached screenshot you can see how I am setting the build command.

Do I need to add a Dockerfile to my project? I never done that before so I am confused on what to do to fix this.

Thank you in advance for reading!

N/A
I don't know where to find my project Id

Hello, how did you come up with this build command?
There's a few flask templates you could reference.
https://railway.app/template/zUcpux

Hey @intro , I'm not completely sure about a solution to you're problem, but here's a good start: you're build script has a bunch of things && together, try doing just one of them at a time and see which ones trigger the error. And yes, using a docker file would probably be a straight forward way to get this to work.

@Finesse it says line 1: npm: command not found so i assume it somehow does not know npm?
It's from a starter project I used before. It comes with user authentication

@intro have you tried not doing a custom build command?
Using the Railway template. (When you first choose a project to deploy, choosing the "deploy flask app" option.

Relevant:
https://railway.app/new/template/zUcpux

to provide you with help we would need to see your repo to understand what's going on with your app

this is the current state of my app:

https://github.com/hannarosenfeld/vault-manager
i used their flask template and modified it a bit. it's still quite simple - see my repo above

you modified it a lot
the template repo didnt have a dockerfile

i added the dockerfile because i obv don't know what i am doing
i just want to deploy my site lol
i need a front and a backend
the backend needs to be flask and the frontend needs to be react

haha no worries, we'll get you sorted
so while we work through this, go ahead and remove the repo from your service so we arent triggering a new build for every little change

remove my github repo from the railway project?

from the railway service
there would be a little x button besides the repo listing in the service settings

this?

yep, you can remove both those

ok just did

okay so you will now want to re-structure your repo into a monorepo
rename react-app to frontend
and then put everything expect readme.md and the frontend folder into a backend folder

should i remove the dockerfile?

ah yes you should, good catch

ok just did
should i push my changes?

yes please

ok done
oh should i have renamed "app" to "backend" ?

if you want to, it is a backend after all

ok done and pushed to main

okay lets get working on the backend first
show me a screenshot of the entire railway project

this?

yep, going forward you will use that service for just your backend, so give it a name that signifies its the service for the backend
later we will create another service for the frontend, but we will cross that bridge when we get to it

ok, and i keep the postgres db?

yes!

give it a name that signifies its the service for the backend

oh i see what you did, you want to change the service name, not the project name
remove the backend suffix from the project name

perfect
rename __init__.py to main.py
and remove the static_folder='../react-app/build', static_url_path='/' stuff from it

ok done and pushed to main

now just do a quick check locally and make sure you can run your backend still

i can

now you will need a railway.json file in your backend, so railway knows how to run the backend service

{
    "$schema": "https://railway.app/railway.schema.json",
    "build": {
        "builder": "NIXPACKS"
    },
    "deploy": {
        "startCommand": "gunicorn main.app"
    }
}

Actually, I am getting an error:

I think it is refering to the .flaskenv

where are you trying to import backend, and why?

i'm not sure.. i am sure though it's from the .flaskenv variable FLASK_APP. Changing it's value changes the value in the error:

remove the file lol

then i can't run the backend anymore

just add

if __name__ == '__main__':
    app.run(debug=True, port=os.getenv("PORT", default=5000))

to the bottom of your main.py file, then you can start the flask server with python main.py

should that be from models import db, user without the period?

no it's User and worked before

the file name has a lower case u

it is refering to the actual user model
changing it to lowercase gives the same error

and yes i know it worked before, but you had an improper directory structure before

yeah it was pretty messy

so please get your codebase working locally before we proceed

since i can't seem to figure this out i will create a minimal flask app and work from there

sounds good

nevermind i am encounterin the same issue here as well when moving my files to the backend as we did earlier

alright no worries, ill be around, just let me know when you are ready to proceed

ok i got a simple app running now. let's take it from here:
https://github.com/hannarosenfeld/vault-manager

i dont think these linked folders will work on railway
i also cant see whats inside of them

apologies, let's try this:
https://github.com/hannarosenfeld/vault-manager

that looks like it shall work

I added the railway file just now

in your backend railway service, set the root directory to /backend then add this repo to the service
ah you had a procfile, so i didnt mention the railway.json file
but now that you have the railway.json leave it, and delete the old style heroku Procfile

done

push the changed then do this

i'm getting the same error i got since the beginning now:

-----

Error: Docker build failed


sorry i realized i still had that old build command in settings. just removed.
building again.

haha beat me to it

the build completed though i can't see my site when i click on the link. deploy logs giving me a bunch of errors. what stands out to me is this: ModuleNotFoundError: No module named 'main.app'; 'main' is not a package

related to the railway file?

oh my bad, it would be main:app

yay it's live now
thank you
i will create my models etc from here and probably be back with more errors at some point ^^

sounds good, let me know when you want to tackle the seprate frontend service
it should be plenty easy to get your original react app running on railway instead of this same react app
for context, frontend solved in a new thread
