Getting started with Dev Containers
summary
Walks through concrete setup steps: VS Code with the dev containers extension, Docker Desktop 4.40, and the template workflow that creates a devcontainer.json committed to the repo. Demonstrates switching PowerShell images (LTS Debian 11 to Debian 12) and seeing PowerShell move from 7.2.19 to PowerShell 7.5, notes a broken postCreate script, shows ~2GB image sizes, and puts a Go API and PowerShell client on the same psummit network so containers talk by name.
