Why does deploying to azure web app fails with no apparent error? How can i retrieve better error logs to fix the issue?

I have a Flask/React webpp that I want to deploy to Azure WebApp but it fails with no apparent reason. I have build and deploy setup like this in packages.json:

    "build": "react-scripts build",
    "deploy": "cd api && az webapp up --sku P1v3",

And invoke them with yarn, yarn deploy completes fine with no errors but yarn deploy gives me the following:

$ yarn deploy
yarn run v1.22.22
$ cd api && az webapp up --sku P1v3

and the log file on the last line doesn't indicate a problem:

also the first error shown on top where it reads Deployment failed because the build process failed suggests that the Oryx container might fail but I'm not sure where or how i would get access to these logs, can someone help me out with this?

UPDATE:

I tried and tried with the above procedure but kept getting stuck and then came across the option to deploy a container from the ACR that runs my application and I figured I would give that a try. So I created a new Dockerfile that would run my application:

FROM node:18.16.0-alpine as build

WORKDIR /app
COPY package.json ./
COPY yarn.lock ./
COPY src/ ./src
COPY public ./public

# Needed since build step is modified in package.json for flask
RUN mkdir ./api

RUN yarn install
ENV NODE_OPTIONS=--openssl-legacy-provider
RUN npx update-browserslist-db@latest
RUN yarn build

FROM python:3.9-buster
RUN  pip install --upgrade pip
COPY api/requirements.txt requirements.txt
RUN  pip install -r ./requirements.txt

COPY api /src/api
COPY --from=build /app/build /src/build
WORKDIR /src/api

# Add the path of the source to the PYTHONPATH to be able to resolve the modules
ENV PYTHONPATH /src

CMD [ "gunicorn", "app:app", "--bind=0.0.0.0:5000" ]

I built it, pushed iyt to the ACR and followed this guide: https://learn.microsoft.com/en-us/training/modules/deploy-run-container-app-service/5-exercise-deploy-web-app?pivots=csharp to setup a new WebApp that run my application in a container image. but i'm unfortunately not having much success either, I just getenter image description here and the kudu logs do not appear to tell me anything either, I tried:

$ tail -f LogFiles/kudu/trace/yvr05dashb_kudu_[Some Id].txt 
2024-10-29T23:21:46  Startup Request, url: /api/deployments/?$orderby=ReceivedTime%20desc&$top=20&api-version=2022-03-01, method: GET, type: request, pid: 87,1,14, ScmType: None

Can someone help me out how I can figure out why the website won't run in the container? Thanks so much!

Solution

  • enter image description here

    Instead of relying on az webapp up, try manually packaging and deploying the application using az webapp deploy with a zip file.

    zip -r app.zip .
az webapp deploy --resource-group ron.eggler_rg_0002 --name jolly-pond-9d2f840394224fd7b4137f53669b613e --src-path app.zip

    Build processes also generate stdout and stderr logs under /LogFiles that can provide additional clues, especially if they contain stack traces or system errors.
