[SOLVED] Can't run $(git rev-parse --short HEAD) in package.json on Virtualbox

Can't run $(git rev-parse --short HEAD) in package.json on Virtualbox

I have a package.json that contains this script:

"scripts": {
    "docker-build": "docker build -t url.com/repository:$(git rev-parse --short HEAD) ."
}

I use this to create automatic tags from Git on mye Docker-images. This works on Mac, but not on a Windows-machine running Docker Quickstart Terminal.

Is it possible to run the $(git rev-parse --short HEAD) command from NPM-script on Windows?

Solution

Unfortunately, even though you might have a bash environment on your windows system, the npm scripts will think they have to run in a Windows shell. (This lack of cross-platform portability is one of the big limitations of npm scripts.)

If having platform-specific scripts is ok, then you could refer to this question for how to do something similar in a windows shell: Batch equivalent of Bash backticks
