I’ve been a fan of docker for years now. As an admin of a windows environment I used to automate legacy windows builds. We had a large docker container that ran in AWS Codebuild to build large artifacts.
I used it on a windows laptop to get to some difficult to install CLI tools like OpenSSL, wget, and curl. You can spend hours and hours digging for windows binaries but a quick docker run and you’ve got a Ubuntu instance and can get to all of your tools.
