update git version in docker container

Question

I am implementing a node.js application in docker, that needs to make use of the git worktree feature. However, even if I do :

RUN apt-get update && apt-get install -y git=2.10.0

Answer 1

As of the time of this post, no package repos from Debian include a version beyond 2.9. If you need a newer version, you'll need to download and install that from source which is documented on git-scm , or find another repo.

Answer 2

From some other answers (credit to @Alex Karshin), this solution works for me in the Dockerfile

RUN apt-get update && \
    apt-get upgrade -y && \
    apt-get install -y git
