This article represents details on installing / setting up Hyperledger Fabric Platform Components / Binaries with emphasis on some of the following:
- Steps for how to install / setup Fabric platform components & docker images
- Details on platform components which are used for setting up the Fabric network
- Details on docker images which comprise Hyperledger Fabric network
The installation leads to download /pull of docker images which are required to run the Blockchain network using Hyperledger Fabric.
Installing Fabric Platform Components & Docker Images
The following command can be used to install Platform binaries:
curl -sSL https://goo.gl/byy2Qj | bash -s 1.0.5
In case Docker commands require sudo, the above command looks like following:
curl -sSL https://goo.gl/byy2Qj | sudo bash -s 1.0.5
The script which gets executed (piped to bash) looks like following:

dockerFabricPull() {
local FABRIC_TAG=$1

echo "==> FABRIC IMAGE: $IMAGES"
echo

done
}
dockerCaPull() {
local CA_TAG=$1
echo "==> FABRIC CA IMAGE"
echo
docker pull hyperledger/fabric-ca:$CA_TAG
docker tag hyperledger/fabric-ca:$CA_TAG hyperledger/fabric-ca
}
: ${CA_TAG:="$MARCH-$CA_VERSION"}
: ${FABRIC_TAG:="$MARCH-$VERSION"}
echo "===> Downloading platform binaries"
curl https://nexus.hyperledger.org/content/repositories/releases/org/hyperledger/fabric/hyperledger-fabric/${ARCH}-${VERSION}/hyperledger-fabric-${ARCH}-${VERSION}.tar.gz | tar xz
echo "===> Pulling fabric Images"
dockerFabricPull ${FABRIC_TAG}
echo "===> Pulling fabric ca Image"
dockerCaPull ${CA_TAG}
echo
echo "===> List out hyperledger docker images"
docker images | grep hyperledger*
Pay attention to some of the following in above script:
- Download / install Docker Fabric images related with platform binaries
- Download / install Docker Fabric CA images
Platform Components / Binaries for setting up Hyperledger Fabric Network
The following binaries get installed within bin folder:
- cryptogen
- configtxgen
- configtxlator
- peer
These binaries help setup the Hyperledger Fabric network.
Docker Images comprising Hyperledger Fabric Network
The following are the Docker container images which get downloaded /pulled as a result of executing above command for installing platform binaries / components. These images represents the components which will comprise Hyperledger Fabric network.
- Fabric tools
- CouchDB: Used to create database to store the world state.
- Kafka
- Zookeeper
- Orderer: Used to created ordering service / consenter service containers which are used for consensus.
- Peer: Used for creating one or more peer (endorser / committer nodes) containers
- Java: Runtime for running Blockchain
- CCEnv
- Fabric CA
