Set up the Blockchain Network
Step 1: Open Docker Desktop, to let the Docker Daemon runs
Once you click open the software, Docker Daemon is already running. No further actions needed.
Step 2: Clone the Hyperledger Fabric Sample repository, pull down the Docker images, and download the platform-specific binary
Determine a directory you want the sample repo to be in and run:
curl -sSL https://bit.ly/2ysbOFE | bash -s
The curl command will perform clone, pull down, download, and show result in both Terminal and Docker Desktop:

Hyperledger Fabric Sample repo
Step 3: Add the bin sub-directory into the PATH environment variable
The curl command executed in step 2 downloaded and executed a bash script that download and extract all of the platform-specific binaries you will need to set up your network and place them into the bin sub-directory. There are ten binaries:
You should add the sub-directory to your PATH environment variable so that these can be picked up without fully qualifying the path to each binary. E.g.:
export PATH={Your fabric-samples repo}/bin:$PATHStep 4: Bring up the network
Go into the test-network sub-directory, run:
cd fabric-samples/test-network
Then, execute another command with the network.sh script:
./network.sh up
This command creates a Fabric network that consists of two peer nodes and one ordering node. The result will be shown in both Terminal and Docker Desktop:

Step 5: Create a channel
Channel is a private layer of communication between specific network members. Channels can be used only by organizations that are invited to the channel, and are invisible to other members of the network. Each channel has a separate blockchain ledger. Organizations that have been invited to join their peers to the channel to store the channel ledger and validate the transactions on the channel.
Now that you have peer and orderer nodes running on your machine, you can use the script to create a channel for transactions between Org1 and Org2.
Let's execute another command with the network.sh script:
./network.sh createChannel
The channel created with the default name 'my channel' will be presented on both Terminal and Docker Desktop:
Terminal
Using docker and docker-compose
Creating channel 'mychannel'.
