The current development environment utilizes Vagrant running an Ubuntu image, which in turn launches Docker containers. Conceptually, the Host launches a VM, which in turn launches Docker containers.
Host -> VM -> Docker
This model allows developers to leverage their favorite OS/editors and execute the system in a controlled environment that is consistent amongst the development team.
- Note that your Host should not run within a VM. If you attempt this, the VM within your Host may fail to boot with a message indicating that VT-x is not available.
- Git client
- Go - 1.6 or later
- Vagrant - 1.7.4 or later
- VirtualBox - 5.0 or later
- BIOS Enabled Virtualization - Varies based on hardware
- Note: The BIOS Enabled Virtualization may be within the CPU or Security settings of the BIOS
Make sure you have properly setup your Host's GOPATH environment variable. This allows for both building within the Host and the VM.
If you are running Windows, before running any git clone
commands, run the following command.
git config --get core.autocrlf
If core.autocrlf
is set to true
, you must set it to false
by running
git config --global core.autocrlf false
If you continue with core.autocrlf
set to true
, the vagrant up
command will fail with the error ./setup.sh: /bin/bash^M: bad interpreter: No such file or directory
Create a fork of the fabric repository using the GitHub web interface. Next, clone your fork in the appropriate location.
cd $GOPATH/src
mkdir -p github.com/hyperledger
cd github.com/hyperledger
git clone https://github.com/<username>/fabric.git
cd $GOPATH/src/github.com/hyperledger/fabric/devenv
vagrant up
NOTE: If you intend to run the development environment behind an HTTP Proxy, you need to configure the guest so that the provisioning process may complete. You can achieve this via the vagrant-proxyconf plugin. Install with vagrant plugin install vagrant-proxyconf and then set the VAGRANT_HTTP_PROXY and VAGRANT_HTTPS_PROXY environment variables before you execute vagrant up. More details are available here: https://github.com/tmatilai/vagrant-proxyconf/
NOTE #2: The first time you run this command it may take quite a while to complete (it could take 30 minutes or more depending on your environment) and at times it may look like it's not doing anything. As long you don't get any error messages just leave it alone, it's all good, it's just cranking.
Once complete, you should now be able to SSH into your new VM with the following command from the same directory.
vagrant ssh
Once inside the VM, you can find the peer project under $GOPATH/src/github.com/hyperledger/fabric (as well as /hyperledger).
NOTE: any time you git clone any of the projects in your Host's fabric directory (under $GOPATH/src/github.com/hyperledger/fabric), the update will be instantly available within the VM fabric directory.
