#Microservice

A production GitHub Actions pipeline for a multi-service .NET solution: build only what changed, cache NuGet and Docker layers, publish to GHCR, deploy over SSH with Compose, and the failure modes that cost the most time.

Run Vault in Docker, lock each .NET service down with AppRole and policies, layer KV secrets over appsettings.json with VaultSharp, issue short-lived database credentials, and fix the 403s and sealed-vault errors you will meet.

Set up Caddy as a reverse proxy with automatic HTTPS using Let's Encrypt SSL and Cloudflare DNS validation in Docker Compose.

Centralize routing, authentication and load balancing in .NET Core microservices with Ocelot API Gateway.

Set up Serilog and Seq in ASP.NET Core properly: bootstrap logging, request logging, trace correlation across services, destructuring, Seq queries, alerts, and the reasons your events never show up.
