# Multi-arch images can be built from this Dockerfile. When the container image is built it is
# expected binaries and a chwrap tar file were already created under bin/ using Make. By default
# calling Make with no arguments builds these files for the current architecture with no suffix
# allowing the container image to be built without multiarch support by default.
#
# If Make is called with the `BUILD_PLATFORMS` build argument, then binaries and chwrap tar files
# will be generated for each platform with an architecture suffix. These can then be used to build a
# multiarch container image using `docker buildx build` by specifying the same list of platforms
# using the `--platform` flag. Note the buildx flag and BUILD_PLATFORMS argument accept slightly
# different values, for example to build for both amd64 and arm64:
#
# `make BUILD_PLATFORMS="linux amd64 amd64 amd64;linux arm64 arm64 arm64" all`
# `docker buildx build --platform=linux/amd64,linux/arm64`
ARG TARGETARCH
# Work around the fact TARGETARCH is not set consistently when building multiarch images using
# release-tools versus docker buildx. While release-tools isn't currently used by GitHub Actions to
# publish multiarch images, this is the only thing preventing use of release-tools, which may be
# useful for local testing.
