but I get this error.

Answer 1

since git wasn't found, it means it either wasn't installed during the image build or wasn't found in the container when you ran it.

You can install git with one of the following (depending on your distro):

• Ubuntu/debian: apt-get install -y git
• Alpine: apk add git
• Centos: yum -y install git

Make sure to upgrade the package list before installing it.

Alternatively, if git is already installed, make sure it is in the PATH, exec into your container and echo the PATH, then check if it includes the location where git is installed.

Based on the provided files, you need to add the following to the Dockerfile.

RUN apk update && apk add git

Answer 2

You must have git in your Dockerfile. Just put this line in your Dockerfile.

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