Fabric Next

Fabric Next is a custom build of Hyperledger Fabric with the following enhancements:

• Cherry-picks of certain features not scheduled to be included in Fabric 1.1
• Experimental build tag enabled
• Dynamic build to allow loading plugins

Build

Prerequisites:

• A Git Client
• Docker - 17.06.2-ce or later
• Docker Compose - 1.14.0 or later
• You may need libtool - sudo apt-get install -y libtool (linux) or brew install libtool (macOS)
• You may need GNU tar on macOS - brew install gnu-tar --with-default-names

Note: The tagged version of fabric-next being used must match the corresponding tag in fabric-snaps. e.g v17.11.1 of fabric-next is compatible with v17.11.1 of fabric-snaps.

To build fabric next run:

$ cd $GOPATH/src/github.com/securekey/fabric-next/scripts
$ ./pull_fabric.sh

This script will cherry-pick fabric next and build it.

'Make' flags used:

• DOCKER_DYNAMIC_LINK=true : Dynamic builds are required to load Go plugins into fabric.
• BASE_DOCKER_NS=securekey : These custom base images include Go 1.9.2 and the C libraries required by fabric for dynamic linking (currently libtool). The Dockerfiles that produce these images can be found in the scripts/images directory. Images are also produced by the script.

(the two flags above may be omitted if you already have a dynamically compiled fabric peer)

• GO_TAGS=pluginsenabled : Enable loading system chaincodes as plugins.
