How to connect to the peer container of the basic-network? I want to see how is the peer doing.

You can use the "docker exec" command to connect to the peer container of the basic-network.

1. Run "docker exec" to create an interactive connect with the peer container:

$ docker exec -it peer0.org1.example.com bash

root@aedfd08717a5:/opt/gopath/src/github.com/hyperledger/fabric#

2. Check the default directory and home directory:

root@aedfd08717a5:/opt/gopath/src/github.com/hyperledger/fabric# ls -l

-rw-r--r-- 1 root root 9234 Apr  1 01:44 mychannel.block

root@aedfd08717a5:/opt/gopath/src/github.com/hyperledger/fabric# cd

root@aedfd08717a5:~# ls -l
total 0

3. Setup membership variables:

root@aedfd08717a5:~# export CORE_PEER_LOCALMSPID=Org1MSP
root@aedfd08717a5:~# export CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/users/Admin@org1.example.com/msp

4. Check the node status and version:

root@aedfd08717a5:~# peer node status
status:STARTED

root@aedfd08717a5:~# peer version
peer:
 Version: 1.4.1
 Commit SHA: 87074a7
 Go version: go1.11.5
 OS/Arch: linux/amd64
 Chaincode:
  Base Image Version: 0.4.15
  Base Docker Namespace: hyperledger
  Base Docker Label: org.hyperledger.fabric
  Docker Namespace: hyperledger

5. List channels:

root@aedfd08717a5:~# peer channel list
Channels peers has joined:
mychannel

6. List chaincodes:

root@aedfd08717a5:~# peer chaincode list --installed
Get installed chaincodes on peer:

As you can see, we are running Peer 1.4.1. The peer joined 1 channel, and has 0 chaincode.
