Can we update git version in the Docker Image?

Question

I'm using docker to install my dependencies. Using Node:10.13.0 as

FROM: node:10.13.0

All dependencies installed well except Husky.

And it shows the following:

Husky requires Git >=2.13.0. Got v2.11.0.   
husky > Failed to install

So, the problem is that the git version is below 2.13.

Searched for init git version in the docker file. But I don't get any solution.

Is any other way to set the git version in the docker file?.

Answer 1

• Next means node:10.13.0 use debian9, aka stretch.

  $ docker run --rm node:10.13.0 cat /etc/issue
  Debian GNU/Linux 9 \n \l
  

• Next means node:10.13.0 default use git 2.11.

  $ docker run --rm node:10.13.0 git --version
  git version 2.11.0
  

In fact, git in debian 9 apt repo use the version 2.11, if you want to upgrade to a newer version, you could use debian backports, which means:

Backports are packages taken from the next Debian release

By default, backports won't be used when use apt. You could use next sample to enable this.

Dockerfile:

FROM node:10.13.0
RUN echo "deb http://deb.debian.org/debian stretch-backports main contrib non-free" >> /etc/apt/sources.list; \
    apt-get update; \
    apt-get -t stretch-backports install git -y

Verify it:

$ docker build -t mynodeimage .

Step 1/2 : FROM node:10.13.0

$ docker run --rm mynodeimage git --version
