# Sysbox at the outer boundary: host dockerd starts the runner via

# even a privileged user sandbox escaping to the runner is not host
# root. Preserves the DinD + internal-registry topology unchanged;
# only the outer runtime shifts. Requires sysbox-runc registered on
# the host dockerd (see 0g-tapp gcp-cvm build-gcp-tapp.sh ENABLE_SYSBOX).

# SECURITY: cross-sandbox network isolation enforcer.
# Shares the runner container's network namespace and inserts an
# iptables rule in the DOCKER-USER chain that drops any packet
# forwarded between two containers on docker0 (the runner's internal
# bridge where all sandboxes live). Reconciles every 60s so the rule
# is restored after runner / dockerd restarts.
#
# docker0 -> docker0 forwarding is exactly cross-sandbox traffic.
# sandbox -> external (egress via eth0) and sandbox -> gateway (INPUT
# to the runner, not FORWARD) are unaffected.
#
# daytona-runner's own iptables persistence loop manages a separate
# set of chains (per-sandbox egress rules); it does not touch
# DOCKER-USER, so this sidecar and daytona-runner coexist cleanly.
#
# Once we upgrade the runner image to v0.179+ this sidecar can be
# replaced by setting `INTER_SANDBOX_NETWORK_ENABLED=false` on the
