# Base images have two different forms:
# * "debug", suffixed as -debug. This is a ubuntu based image with a bunch of debug tools
# * "distroless", suffixed as -distroless. This is distroless image - no shell. proxyv2 uses a custom one with iptables added
# * "default", no suffix. This is currently "debug"

# This can be done with DOCKER_BUILD_VARIANTS="default debug" as well, but at the expense of building twice vs building once and tagging twice
