From 101e6f6b74d4ddda1f3e5a4332ca8b072fb1a872 Mon Sep 17 00:00:00 2001 From: Matthew Heon Date: Thu, 14 Mar 2019 16:25:47 -0400 Subject: Add support for SCTP port forwarding SCTP is already present and enabled in the CNI plugins, so all we need to do to add support is not error on attempting to bind ports to reserve them. I investigated adding this binding for SCTP, but support for SCTP in Go is honestly a mess - there's no widely-supported library for doing it that will do what we need. For now, warn that port reservation for SCTP is not supported and forward the ports.
