# For components which build the same versions across multiple kube versions
# we use the first version which has the same git_tag as the current project build
# as the buildctl import-cache to try and converge as many builds to the same image in ecr
# This isnt neccessary since on the subsequent builds they should converge, but building
# kube first for newer versions while build all other components gives us the best chance
# to converge on the same image in the first build. This also doesnt handle cases where the
# first version is different but the next 3 are the same, in those cases it would still
# take two builds to converge
