Using a Makefile to get latest git tag

Question

I have a Makefile which I use to build my docker image.

NAME = demo/docker-test

default: build

build:
    docker build -t $(NAME) .

push:
    docker push $(NAME)

I would like to append to the build the latest version from my Git tags ie

build:
    docker build -t $(NAME):$(VERSION) .

So if I have 3 tags in Git v.1.2 , v.1.3 , v.1.4 VERSION would be v.1.4 .

Is this possible in a Makefile? If so how, where do I start?

Answer 1

git describe --tags 

Should give you the output needed

From there you should be able to check out the files in the make script
