A build script should be simple, extensible and compile native.
Generally shell scripts do great job as build scripts. But if your development environment consist of Linux, Windows and Docker environments, shell script do not run out of the box on every platform. As well scripting languages like python need dependencies and are difficult to maintain for different platforms.
The solution would be a script which can run without dependencies on every platform. The solution I picked is “golang”. Runs as script, compiles native, easy to cross compile and does not need any dependencies.
Since all artifacts produces are docker images, the script is called “captain”
