Overview


Deploying a Blazor Server app to Azure is straightforward with the right setup. This guide walks through App Service deployment with automated CI/CD.


Prerequisites


  • Azure subscription
  • GitHub repository
  • Azure CLI installed

    • Create the App Service


    
az group create --name MyBlogRG --location eastus
az appservice plan create --name MyBlogPlan --resource-group MyBlogRG --sku B1
az webapp create --name mytechblog --resource-group MyBlogRG --plan MyBlogPlan --runtime "DOTNETCORE:10.0"

    GitHub Actions Workflow


    Add .github/workflows/deploy.yml to automate deployments on every push to main:


    
on:
  push:
    branches: [main]
jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-dotnet@v4
        with:
          dotnet-version: '10.0.x'
      - run: dotnet publish -c Release -o ./publish
      - uses: azure/webapps-deploy@v3
        with:
          app-name: mytechblog
          publish-profile: ${{ secrets.AZURE_PUBLISH_PROFILE }}
          package: ./publish
