 Why you need Docker engine for Hyperledger fabric?   

Hyperledger fabric uses different docker containers, like ordering service has its own docker container, chaincode has its own etc.

 Why you need to install go language? 

Go language is used to develop the smart contracts (chaincode) in Hyperledger Fabric.
