export VERSION_NUMBER=1.0.0
Instead of 1.0.0 can we make this one dynamic ? Thanks for you script

Using CodeBuild to build my image, I used CODEBUILD_BUILD_NUMBER as the incremental build number to tag to images. Its a far easier solution and goes a long way to automate.

Or, if you'd like to derive it from package.json in the repo, use

export VERSION_NUMBER=$(cat package.json | jq '.version' | sed -e 's/^"//' -e 's/"$//')

If you are like me looking for that solution but for github workflow i made this:
