Creating a Docker Image with Git Installed
Version control is one of the most important aspects of any software development project and when we talk about version control, there is no better tool than Git. The majority of the developers depend upon Git to manage and share their project components among the team members.
Even if you are running your project on Docker, you can still access your git account inside Docker Containers. All you need to do is just install Git inside your Docker Container. In this article, we will discuss exactly the same. We will create an Ubuntu Image, install Git inside it, create a Container associated with the Image, and verify whether Git has been installed or not.
