Chaincode setup Hyperledger Fabric

I'm trying to setup Hyperledger Fabric chaincode development setup in my MAC machine. I already have the development environment setup, but my end goal is to just develop a blockchain application on top of Hyperledger Fabric. So I am moving towards the docker chaincode developement and test environment. I'm following the instructions given here (following the Option 2). The docker-compose up command is throwing the following error :

himanshus-mbp:fabric himanshutyagi$ docker-compose up
Recreating fabric_membersrvc_1
Creating fabric_vp_1

ERROR: for vp  driver failed programming external connectivity on endpoint fabric_vp_1 (98887f3aa674ed269b3bf9cae87f28d7686920343a9cb2aac5f2715b1a945da8): Error starting userland proxy: write /port/tcp:0.0.0.0:5000:tcp:172.17.0.2:5000/ctl: errno 526
ERROR: Encountered errors while bringing up the project.

There is nothing related to this on the github issues. Can anyone explain what might be going wrong ?

If you know what process is running at port 5000 then try with sudo lsof -i tcp:5000 then note the process id and run sudo kill -15 <PROCESS_ID_HERE>. After that retry running docker commad

The port is probably already in use by another process. Has it already been started or is another program using the port. Use lsof to help find the process.
