In the startFabric.sh launch the cli container using:
docker-compose -f ./docker-compose.yml up -d cli
In your compose yaml file, you should see something like this:
./../chaincode/:/opt/gopath/src/github.com/
If you see this declaration, copy in your local machine the folder /hyperledger/fabric/core/chaincode/lib/cid into your chaincode folder. You should find it in chaincode/abac if you are using the last version of fabric samples
