mcpcontrol: policy based routing for INSTALLER_IP
To bypass Docker 'bridge'-backed network isolation, we previously added an extra routing hop, which broke access from inside the 'mcpcontrol' Docker network (typically 10.20.0.0/24) to its bridge address (10.20.0.1), leading to DNS issues on Salt Master. This change leverages policy based routing to only add the extra routing hop for connections originating from the default Docker bridge network ('docker0'). Note that other Docker networks using the 'bridge' driver are still isolated from 'mcpcontrol'. Fixes: d9b44acb Change-Id: Ib92901c3278ae9b815f28f26d4c26f82bcadacd6 Signed-off-by: Alexandru Avadanii <Alexandru.Avadanii@enea.com> (cherry picked from commit c7a28fcf419f78aa44af8800e1f35e47471c4bb0)
