No connection to monero daemon on the same machine
I have monero daemon running in a docker container on the same machine (hvalev/monero-node:latest).  Ports 18089 & 18083 additionally published. But p2pool container is not able to connect to that (RPC connection failure). 

My command line for p2pool is:
--host 127.0.0.1 --rpc-port 18089 --wallet <<MyWallet-Number>> --stratum 0.0.0.0:3333 --p2p 0.0.0.0:37889 --addpeers 65.21.227.114:37889,node.sethforprivacy.com:37889

Am I doing something wrong or is it a bug?
