Unable to Register Chaincode & Successfully Start Blockchain Network - docker

Question

I am following hyperledger fabric tutorial, and am having trouble registering my chaincode and possibly starting the docker image:
https://www.ibm.com/developerworks/library/j-chaincode-for-java-developers/
The following is the error I am getting when I try to register my chaincode:
$ ./Example

SEVERE: Unable to connect to peer server: UNAVAILABLE
My blockchain network via docker is up and running, but the last log message is different than the expected log message (It says Connected to: [], which I assume is a null):
05:47:30.205 [peer] chatWithSomePeers -> DEBU 02f Starting up the first peer of a new network

05:47:36.209 [peer] ensureConnected -> DEBU 038 Discovery knows about: []
When I check for containers that are running docker shows me both of them are up, see below:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
7dec77752d52 hyperledger/fabric-peer "sh -c 'sleep 5; peer" 20 minutes ago Up 20 minutes 0.0.0.0:7050-7051->7050-7051/tcp, 0.0.0.0:7053->7053/tcp blockchain_vp0_1

The following git command was used:
git clone https://github.com/hyperledger/fabric.git -b v0.6
I copied and pasted the exact values for the docker-compose.yml, see below:
membersrvc:
image: hyperledger/fabric-membersrvc
ports:
- "7054:7054"
command: membersrvc
vp0:

Is there something I am missing here? Any help is appreciated, thank you.

Seems you are working on Windows environment and did everything right except not defined any port forwarding into Oracle VM virtual box. you will have to configure
Oracle VM VirtualBox Manager - > Setting - > Network -> Advance - > port forwarding -- and define as per attached image, run and enjoy.... enter image description here
Happy Coding!
