I have found a way to build Windows container images without Docker - It doesn't use a Dockerfile though.

The way I got this to work is using crane from Google (https://github.com/google/go-containerregistry/blob/main/cmd/crane/doc/crane.md) which lets you append image layers to a base image. You can build Windows images on either Linux or Windows or inside of a container (Linux/Windows) - however, you'll need to build any artefacts (e.g. EXE, DLLs) on a Windows machine since this approach is using Crane to assemble a Windows container image on a Linux host (container).

Here is a quick PoC I did to prove it works (using Docker Desktop with Windows Container mode on my laptop):

dotnet --version
# 7.0.102

Note: currently, release annotations only work with the classic metrics explorer.

# Guidance/Steps:
- Enable Application Insights for the prod web app
- Ensure the App Insights Instrumentation Key is correct in the web app Application Settings, set APPINSIGHTS_INSTRUMENTATIONKEY (to be extra safe, also add Keys:ApplicationInsights:InstrumentationKey with the same value since the code looks that setting up)
- Restart the web app (prod) and navigate to a few URLs in the web app, check that you can see metrics (server response time) appears in App Insights (prod) – reduce time scale to 30 mins

## Add release annotations
- See: https://docs.microsoft.com/en-us/azure/azure-monitor/app/annotations
- Edit the prod stage in the release pipeline

Note: The Azure DevOps Pipelines release gates for Azure Monitor alerts appear to (currently) only support Classic Alerts.

# Guidance/Steps:
Pre-requisites (Lab 5) – app insights enable, server delay introduced

## Setup the alert
- From App Insights (prod), go to Configure / Alerts, then click “View classic alerts” from the top nav bar
- Click “Add metric alert (classic)”
- Enter name “slow-server”
- Select the prod App Insights instance
