Name
awwall — Say what a workload may reach, and watch everything else fail closed.
The problem it solves
Every other gate asks about the CALLER — who they are, what role they hold, whether they are human. Nothing asks what a workload is allowed to REACH. So a service quietly dials whatever its config says, and when that config is stale the failure is a DNS or connect error naming a host with no relationship to the problem — the symptom points at an innocent service. Measured on our own fleet 2026-08-23: 11 registry entries pointed at hosts that did not exist while the real container was running, and every one of those failures named the wrong subsystem.
Instead of trusting / you check
- instead of trusting
- that a service only talks to the hosts you think it talks to
- you check
- an explicit egress allowlist, where a denial names the rule that denied it
Adopt it alone
Block one outbound host for one workload and watch the call fail closed with the rule that denied it.
Install
pip install awwall
