I am using Puppeth provided as part of go-ethereum. It is able to create the containers with geth, all working fine. How to send transaction into this private blockchain via Metamask. I don't see either --rpc flag or rpc port mapping to host. Can someone help connecting metamask to private blockchain created via puppeth. Thanks.
