Deploy

Goal

This snapshot advances Northline Press by teaching you to prepare Northline Press for Azure Container Apps and managed Postgres.

Every numbered folder is a complete app. Run this stage independently, then compare it with the previous folder.

Prerequisites

Use .NET 8 SDK, a terminal, and Docker for Postgres stages. You should recognize C#, HTTP verbs, and basic HTML.

Port 5080 must be free. Copy .env.example and review appsettings.json before database stages.

• .NET 8 SDK
• A code editor and terminal
• Docker from part 4 onward

Concepts

Production needs HTTPS-only cookies, a strong connection string, and environment-only secrets.

Keep page models thin: Razor Pages accept input, services and EF Core enforce rules, and Razor escapes output by default.

Walkthrough

Review the Dockerfile and DEPLOY.md, set connection strings and CookieSecure in Azure, and never commit production secrets.

Read the example, then open the matching snapshot. The repository includes the surrounding setup and error handling.

CookieSecure=true
ConnectionStrings__DefaultConnection=Host=...

Run and verify

Enter 12-Deploy, restore packages, and run on port 5080.

Open http://127.0.0.1:5080. Watch the terminal for validation and database errors.

docker compose up -d
git clone https://github.com/michaeldunga1/fcc-aspnet-blog.git
cd fcc-aspnet-blog/12-Deploy
cp .env.example .env
dotnet restore
dotnet run --urls http://127.0.0.1:5080

Troubleshooting

If sessions vanish after deploy, check secure cookie settings behind HTTPS ingress.

Restore errors usually mean the SDK is missing or you opened the wrong folder. For Postgres failures, confirm Docker is running and the northline_NN database name matches the snapshot.

• Read the first error first
• Restart after environment changes
• Never commit .env or production secrets

Try this

List every secret that must live only in the host environment.

Test a happy path and one invalid or unauthorized request.

• Make one small change
• Test it in the browser
• Compare with the next snapshot only after it works
