# This docker image is based on yq docker image, but with additional pkgs for specific uses.
# We didnt add yq to other build image because:
# 1. We want to keep the image as slim as possible for specific use case.
# 2. It is not easy to install yq as it is not part of default package manager repositories on RHEL/Ubuntu
# 3. Alpine can install yq with apk from the get go, and does not have the official yq image entrypoint
#    which will cause jenkins to not able to `cat` and hold the container.
# Thanks.
