What is the problem this feature will solve?

When using kubectl diff, it is useful to have color in the output, highlighting the diff in a pretty way. This is possible by setting the KUBECTL EXTERNAL DIFF environment variable along with a tools like colordiff. A common use case is automation pipelines, when it is best to view things in the most human-readable way possible.

Hi, thanks for the suggestion. We try to find a balance between usability and limiting the number of packages installed by default to reduce the size and attack surface in the image.
We'll keep the issue open just in case there is more demand from the community to use this package, in the meantime, you can extend the Dockerfile adding the package and building your own image.
