# This build arg allows the specification of a custom Golang image.
ARG GOLANG_IMAGE=golang:1.22.5
# The distroless image on which the CPI manager image is built.
#
# Please do not use "latest". Explicit tags should be used to provide
# deterministic builds. This image doesn't have semantic version tags, but
# the fully-qualified image can be obtained by entering
# "gcr.io/distroless/static:latest" in a browser and then copying the
# fully-qualified image from the web page.
