NiceGUI deployment to Railway help with dockerfile
Hi I hope someone can help me. So far I am loving Railway. I already have a Django project and it runs fine. Now I am using nicegui to build an app but I cannot get the deployment to Railway working. App Code is mostly in main.py
How to deploy my nicegui app to railway?
I created a dockerfile and it seems succesfully running but I think uvicorn is not running?
Code is below:
# Pull the official base image
FROM python:3.10-slim-buster
# Set environment variables
ENV PYTHONDONTWRITEBYTECODE 1
ENV PYTHONUNBUFFERED 1
# The port environment variable is set by Railway when the container is run
# But we can default it to 8080 for local development
ENV PORT=8080
# Expose the port
EXPOSE $PORT
# Set work directory in the container
WORKDIR /code
# Install dependencies
COPY requirements.txt /code/
RUN pip install --upgrade pip
RUN pip install -r requirements.txt
# Copy project
COPY . /code/
# Command to run on container start
CMD ["python", "main.py"]
In the console I get the feed:
NiceGUI ready to go on http://localhost:8080, and http://172.17.2.235:8080
But i think i need to expose it with the uvicorn? Can someone help?

Project ID:
3e62bf9f-3eee-4bbd-80e8-83d7d0e2acf1is nicegui a fastapi app?
Hi yes it is fast api and just py i believe
do you have uvicorn in your requirements.txt file?
Need to check i believe it is.
in the main.py file, is the fastapi variable called
app ?No there is no app definition in the main.py it is not needed for niceGUI.
See docs of nicegui it just runs with python main.py and no ref needed for an app variable
send me the docs please
try setting a
PORT service variable to 8080hi i see on their site also this info
You can run it if you only have main.py with
docker run -it --rm -p 8888:8080 \
-v "$PWD":/app zauberzeug/nicegui
i did in the docker file
But we can default it to 8080 for local development
ENV PORT=8080
It is running
NiceGUI ready to go on http://localhost:8080/, and http://172.17.2.235:8080/
I think i have some ip mapping wrong or need to add extra line for uvicorn?
