Hello, sorry to interrupt, but did you find a solution to be able to connect to the cluster from a client on the host machine?

I tried with alternatives like this but without success:

rm -rf /.ethereum/tmpprivate; geth --datadir=/.ethereum/tmpprivate --networkid=456789 --genesis=~/Docker/ethereum-docker/files/genesis.json --bootnodes='enode://288b97262895b1c7ec61cf314c2e2004407d0a5dc77566877aad1f2a36659c8b698f4b56fd06c4a0c0bf007b4cfb3e7122d907da3b005fa90e724441902eb19e@192.168.99.100:30303'

While doing a tcpdump on the bootstrap docker machine, I can see that a message is received, but the 30303 port is unreachable. Note that the bootstrap machine took a random port.

You can connect using RPC from your host machine:
mist --rpc http://localhost:8545
