# BuildKit daemon — privileged image builder for CI runners.
# Runs as root with privileged=true in the isolated ci namespace.
# Rootless mode (moby/buildkit:*-rootless) fails on k3s/containerd because
# rootlesskit cannot share mount propagation on the container root fs.
#
# Runners connect via TCP: DOCKER_HOST=tcp://buildkitd.ci.svc.cluster.local:1234
