In a Container is Wave Server neded or i can just make pip install h2o_wave

I'm creating a container with a h2owave app and i'm getting the folowing error:

result = await app(self.scope, self.receive, self.send)
File "/opt/venv/lib/python3.9/site-packages/uvicorn/middleware/proxy_headers.py", line 45, in call
return await self.app(scope, receive, send)
File "/opt/venv/lib/python3.9/site-packages/uvicorn/middleware/asgi2.py", line 7, in call

Hi @rmfjd78, although you did not post the whole error stack trace, by looking at the dockerfile, I assume the problem is your app cannot connect to the Wave server (waved) since I do not see starting it anywhere. You have 2 options how to go about this:

• for Wave > 0.20, waved is packaged together with py distribution so you should be able to simple use wave run your-app within CMD. This is the simplest, least flexible solution.
• Another solution is to run waved and wave app separately (the only option for Wave < 0.19). This approach is a bit more complex, but allows for more config flexibility. From what you have posted, I do not see waved startup. See docs: blog - deploying wave apps on heroku #1234 for guide on how to dockerize Wave.

Since i’m using the lates version of the h2o_wave in my container i have the following problem when i start the container and try to access my App in the browser the page doesn’t load. Do i need to configure anything in the container (proxy, ….) or the wave command needs extra parameters?

[mturoci]

Try this:

# Get base image with python installed.
FROM python:3.8
# Copy over everything.
COPY . .
# Install needed dependencies.
RUN pip install -r requirements.txt
# Run the app.
CMD ["wave", "run", "--no-reload", "app.py"]
