Setting Up a Network For Development in Hyperledger Fabric v0.5-preview

My demo project is running OK already, but it is only one peer in network. I want to add more peers into network. I followed this guide ==> https://github.com/hyperledger-archives/fabric/blob/540c4db5f64dba4bd1b18e896c96a8d17d7ec552/docs/dev-setup/devnet-setup.md.

Please kindly help to check the log below, the directory was wrong? or what is the right way to run this start up of peer?

vagrant@hyperledger-devenv:v-:/opt/gopath/src/github.com/hyperledger/fabric$ docker run --rm -it -e CORE_VM_ENDPOINT=http://172.17.0.1:2375 -e CORE_PEER_ID=vp0 -e CORE_PEER_ADDRESSAUTODETECT=true hyperledger-peer peer node start
Unable to find image 'hyperledger-peer:latest' locally
Pulling repository docker.io/library/hyperledger-peer
docker: Error: image library/hyperledger-peer not found.
See 'docker run --help'.

Is it possible that first node in network was started not in Docker container? (For example it could be started as a process using peer node start)

We can verify which docker images are available in vagrant machine. Just run docker images command:

vagrant@hyperledger-devenv:v0.0.9-b4acc4b:$ docker images
REPOSITORY                     TAG                 IMAGE ID            CREATED             SIZE
hyperledger/fabric-baseimage   latest              c1d6f4800a55        27 hours ago        1.297 GB
hyperledger/fabric-baseimage   x86_64-0.0.9        70328eed56aa        2 weeks ago         990.1 MB
busybox                        latest              47bcc53f74dc        9 weeks ago         1.113 MB

With such configuration, when “hyperledger-peer” image is not available, the Validation Peer will not be started because of “Unable to find image” error:

vagrant@hyperledger-devenv:v0.0.9-b4acc4b:/opt/gopath/src/github.com/hyperledger/fabric/peer$ docker run --rm -it -e CORE_VM_ENDPOINT=http://172.17.0.1:2375 -e CORE_PEER_ID=vp0 -e CORE_PEER_ADDRESSAUTODETECT=true hyperledger-peer peer node start
Unable to find image 'hyperledger-peer:latest' locally
Pulling repository docker.io/library/hyperledger-peer
docker: Error: image library/hyperledger-peer not found.

"hyperledger-peer:latest" image can be created using:

cd $GOPATH/src/github.com/hyperledger/fabric/core/container
go test -run BuildImage_Peer

Now docker images should show one more available image:

REPOSITORY                     TAG                 IMAGE ID            CREATED             SIZE
hyperledger-peer               latest              438b65f18f21        8 seconds ago       1.418 GB

at this point Validation Peer should be started successfully: 

vagrant@hyperledger-devenv:v0.0.9-b4acc4b:~$ docker run —rm -it -e CORE_VM_ENDPOINT=http://172.17.0.1:2375 -e CORE_PEER_ID=vp0 -e CORE_PEER_ADDRESSAUTODETECT=true hyperledger-peer peer node start
