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

Error: Docker build failed

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

22 |     # build phase

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!

Project ID: N/A

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.

intro 🇮🇹•15mo ago

@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

2.7182•15mo ago

@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

Brody•15mo ago

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

intro 🇮🇹•15mo ago

this is the current state of my app: https://github.com/hannarosenfeld/vault-manager

intro 🇮🇹•15mo ago

i used their flask template and modified it a bit. it's still quite simple - see my repo above

Brody•15mo ago

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

intro 🇮🇹•15mo ago

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

Brody•15mo ago

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

intro 🇮🇹•15mo ago

remove my github repo from the railway project?

Brody•15mo ago

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

intro 🇮🇹•15mo ago

this?

Brody•15mo ago

yep, you can remove both those

intro 🇮🇹•15mo ago

ok just did

Brody•15mo ago

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

intro 🇮🇹•15mo ago

should i remove the dockerfile?

Brody•15mo ago

ah yes you should, good catch

intro 🇮🇹•15mo ago

ok just did should i push my changes?

Brody•15mo ago

yes please

intro 🇮🇹•15mo ago

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

Brody•15mo ago

if you want to, it is a backend after all

intro 🇮🇹•15mo ago

ok done and pushed to main

Brody•15mo ago

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

intro 🇮🇹•15mo ago

this?

Brody•15mo ago

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

intro 🇮🇹•15mo ago

ok, and i keep the postgres db?

Brody•15mo ago

yes!

intro 🇮🇹•15mo ago

Brody•15mo ago

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

intro 🇮🇹•15mo ago

Brody•15mo ago

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

intro 🇮🇹•15mo ago

ok done and pushed to main

Brody•15mo ago

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

intro 🇮🇹•15mo ago

i can

Brody•15mo ago

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"
    }
}

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

intro 🇮🇹•15mo ago

Actually, I am getting an error: I think it is refering to the .flaskenv

Brody•15mo ago

where are you trying to import backend, and why?

intro 🇮🇹•15mo ago

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:

Brody•15mo ago

remove the file lol

intro 🇮🇹•15mo ago

then i can't run the backend anymore

Brody•15mo ago

just add

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

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

intro 🇮🇹•15mo ago

Brody•15mo ago

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

intro 🇮🇹•15mo ago

no it's User and worked before

Brody•15mo ago

the file name has a lower case u

intro 🇮🇹•15mo ago

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

Brody•15mo ago

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

intro 🇮🇹•15mo ago

yeah it was pretty messy

Brody•15mo ago

so please get your codebase working locally before we proceed

intro 🇮🇹•15mo ago

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

Brody•15mo ago

sounds good

intro 🇮🇹•15mo ago

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

Brody•15mo ago

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

intro 🇮🇹•15mo ago

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

intro 🇮🇹•15mo ago

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

Brody•15mo ago

that looks like it shall work

intro 🇮🇹•15mo ago

I added the railway file just now

Brody•15mo ago

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

intro 🇮🇹•15mo ago

done

Brody•15mo ago

push the changed then do this

intro 🇮🇹•15mo ago

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

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

Brody•15mo ago

haha beat me to it

intro 🇮🇹•15mo ago

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

intro 🇮🇹•15mo ago

intro 🇮🇹•15mo ago

related to the railway file?

Brody•15mo ago

oh my bad, it would be main:app

intro 🇮🇹•15mo ago

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 ^^

Brody•15mo ago

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
