Docker
Docker is actually really easy to use. I would highly recommend the use of Docker-Compose over Docker Desktop.
Docker Desktop
For Windows this requires the installation of WSL2.
Docker-Compose
Compose files are written in YAML, and define the containers, their parameters, and how they operate
To run a compose file, use docker-compose up -d
SQL Server
Volumes & Persisting Data
In theory, you're using this to run a SQL Server instance, so naturally you'll want to persist your data. Doing so is actually pretty easy.
You just need to utilize volumes.
Sample SQL Server Compose File
