Hyperledger Fabric Samples

Note

If you are running on Windows you will want to make use of the Docker Quickstart Terminal for the upcoming terminal commands. Please visit the Prerequisites if you haven’t previously installed it.

If you are using Docker Toolbox on Windows 7 or macOS, you will need to use a location under C:\Users (Windows 7) or /Users (macOS) when installing and running the samples.

If you are using Docker for Mac, you will need to use a location under /Users, /Volumes, /private, or /tmp. To use a different location, please consult the Docker documentation forfile sharing.

If you are using Docker for Windows, please consult the Docker documentation for shared drives and use a location under one of the shared drives.

Determine a location on your machine where you want to place the Hyperledger Fabric samples applications repository and open that in a terminal window. Then, execute the following commands:

git clone -b master https://github.com/hyperledger/fabric-samples.git
cd fabric-samples
git checkout {TAG}

Note

To ensure the samples are compatible with the version of Fabric binaries you download below, checkout the samples {TAG} that matches your Fabric version, for example, v1.1.0. To see a list of all fabric-samples tags, use command “git tag”.

Download Platform-specific Binaries

Next, we will install the Hyperledger Fabric platform-specific binaries. This process was designed to complement the Hyperledger Fabric Samples above, but can be used independently. If you are not installing the samples above, then simply create and enter a directory into which to extract the contents of the platform-specific binaries.

Please execute the following command from within the directory into which you will extract the platform-specific binaries:

curl -sSL https://goo.gl/6wtTN5 | bash -s 1.1.0

Note

If you get an error running the above curl command, you may have too old a version of curl that does not handle redirects or an unsupported environment.

Please visit the Prerequisites page for additional information on where to find the latest version of curl and get the right environment. Alternately, you can substitute the un-shortened URL: https://github.com/hyperledger/fabric/blob/master/scripts/bootstrap.sh

Note

You can use the command above for any published version of Hyperledger Fabric. Simply replace ‘1.1.0’ with the version identifier of the version you wish to install.

The command above downloads and executes a bash script that will download and extract all of the platform-specific binaries you will need to set up your network and place them into the cloned repo you created above. It retrieves four platform-specific binaries:

• cryptogen,
• configtxgen,
• configtxlator,
• peer
• orderer and
• fabric-ca-client

and places them in the bin sub-directory of the current working directory.

You may want to add that to your PATH environment variable so that these can be picked up without fully qualifying the path to each binary. e.g.:

export PATH=/bin:$PATH

Finally, the script will download the Hyperledger Fabric docker images from Docker Hub into your local Docker registry and tag them as ‘latest’.

The script lists out the Docker images installed upon conclusion.

Look at the names for each image; these are the components that will ultimately comprise our Hyperledger Fabric network. You will also notice that you have two instances of the same image ID - one tagged as “x86_64-1.x.x” and one tagged as “latest”.
