Eu implantei um FastAPI para aplicativos da web do Azure. Eu usei o seguinte yaml:
webapps-actions
name: Build and deploy Python app to Azure Web App - fast-api-port
on:
push:
branches:
- main
workflow_dispatch:
jobs:
build:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- name: Set up Python version
uses: actions/setup-python@v5
with:
python-version: '3.12'
- name: Create and start virtual environment
run: |
python -m venv venv
source venv/bin/activate
- name: Install dependencies
run: pip install -r requirements.txt
# Optional: Add step to run tests here (PyTest, Django test suites, etc.)
- name: Zip artifact for deployment
run: zip release.zip ./* -r
- name: Upload artifact for deployment jobs
uses: actions/upload-artifact@v4
with:
name: python-app
path: |
release.zip
!venv/
deploy:
runs-on: ubuntu-latest
needs: build
environment:
name: 'Production'
url: ${{ steps.deploy-to-webapp.outputs.webapp-url }}
permissions:
id-token: write #This is required for requesting the JWT
steps:
- name: Download artifact from build job
uses: actions/download-artifact@v4
with:
name: python-app
- name: Unzip artifact for deployment
run: unzip release.zip
- name: Login to Azure
uses: azure/login@v2
with:
client-id: ${{ secrets.AZUREAPPSERVICE_CLIENTID_xx }}
tenant-id: ${{ secrets.AZUREAPPSERVICE_TENANTID_xx }}
subscription-id: ${{ secrets.AZUREAPPSERVICE_SUBSCRIPTIONID_xx }}
- name: 'Deploy to Azure Web App'
uses: azure/webapps-deploy@v3
id: deploy-to-webapp
with:
app-name: 'fast-api-port'
slot-name: 'Production'
Posso ver que os arquivos agora existem no servidor:
Entretanto, quando navego até a URL do aplicativo da web, recebo o seguinte:
Como inicio o servidor uvicorn na implantação? De alguma forma, preciso do fastapi para começar.
Adicionei o seguinte na Configuração:

Testei seu código e implantei com sucesso no aplicativo Web do Azure sem problemas.
Recebi o mesmo erro depois de implantar o aplicativo, então, para resolver o problema, configurei o comando de inicialização abaixo na seção de configuração do meu aplicativo Web do Azure.
