# Secure-path bench: step-ca (fleet CA) + FreeRADIUS (EAP-TLS), on the SERVING
# host (the trusted side). The authenticator (hostapd-wired + MACsec) is NOT
# here — it runs on a node between each workstation and this host (see
# authenticator/). Host networking so FreeRADIUS sees RADIUS/1812 from the
# authenticator and step-ca is reachable for enrolment.

#   cp .env.example .env   # set CA_DNS / CA_PASSWORD / RADIUS_SECRET

# Images are pulled from Docker Hub here; mirror them through your registry
# (like the serving stack does for nginx/alpine) if you don't have egress.
