name: probe registry from buildkitd
# TEMPORARY probe branch — not for merge.
#
# The first probe ran in the RUNNER pod. buildkitd is a different pod in a
# different namespace with its own NetworkPolicies, so those results cannot be
# transferred: an UNREACHABLE there may be the runner's policy, not routing.
# This runs the same probes THROUGH buildkitd, by building a stage whose RUN
# does the curling — that egresses from the buildkitd pod, which is the network
# position that actually has to push.
#
# It prints results and always exits 0: this is a measurement, not a gate.
