Setting up the development environment¶
Prior to the v1.0.0 release, the development environment utilized Vagrant running an Ubuntu image, which in turn launched Docker containers as a means of ensuring a consistent experience for developers who might be working with varying platforms, such as macOS, Windows, Linux, or whatever. Advances in Docker have enabled native support on the most popular development platforms: macOS and Windows. Hence, we have reworked our build to take full advantage of these advances. While we still maintain a Vagrant based approach that can be used for older versions of macOS and Windows that Docker does not support, we strongly encourage that the non-Vagrant development setup be used.
Note that while the Vagrant-based development setup could not be used in a cloud context, the Docker-based build does support cloud platforms such as AWS, Azure, Google and IBM to name a few. Please follow the instructions for Ubuntu builds, below.
- Git client
- Go - 1.7 or later (for releases before v1.0, 1.6 or later)
- For macOS, Xcode must be installed
- Docker - 1.12 or later
- Docker Compose - 1.8.1 or later
- (macOS) you may need to install gnutar, as macOS comes with bsdtar as the default, but the build uses some gnutar flags. You can use Homebrew to install it as follows:
brew install gnu-tar --with-default-names
pip install --upgrade pip pip install behave nose docker-compose pip install -I flask==0.10.1 python-dateutil==2.2 pytz==2014.3 pyyaml==3.10 couchdb==1.0 flask-cors==2.0.1 requests==2.4.3 pyOpenSSL==16.2.0 pysha3==1.0b1 grpcio==1.0.4 #PIP packages required for some behave tests pip install urllib3 ndg-httpsclient pyasn1 ecdsa python-slugify grpcio-tools jinja2 b3j0f.aop six
Set your GOPATH¶
Make sure you have properly setup your Host’s GOPATH environment variable. This allows for both building within the Host and the VM.
In case you installed Go into a different location from the standard one your Go distribution assumes, make sure that you also set GOROOT environment variable.
Note to Windows users¶
If you are running Windows, before running any
git clone commands,
run the following command.
git config --get core.autocrlf
core.autocrlf is set to
true, you must set it to
git config --global core.autocrlf false
If you continue with
core.autocrlf set to
vagrant up command will fail with the error:
./setup.sh: /bin/bash^M: bad interpreter: No such file or directory
Cloning the Fabric project¶
Since the Fabric project is a
Go project, you’ll need to clone the
Fabric repo to your $GOPATH/src directory. If your $GOPATH has multiple
path components, then you will want to use the first one. There’s a
little bit of setup needed:
cd $GOPATH/src mkdir -p github.com/hyperledger cd github.com/hyperledger
Recall that we are using
Gerrit for source control, which has its
own internal git repositories. Hence, we will need to clone from
For brevity, the command is as follows:
git clone ssh://LFID@gerrit.hyperledger.org:29418/fabric && scp -p -P 29418 LFID@gerrit.hyperledger.org:hooks/commit-msg fabric/.git/hooks/
Note: Of course, you would want to replace
LFID with your own
Linux Foundation ID.
Bootstrapping the VM using Vagrant¶
If you are planning on using the Vagrant developer environment, the following steps apply. Again, we recommend against its use except for developers that are limited to older versions of macOS and Windows that are not supported by Docker for Mac or Windows.
cd $GOPATH/src/github.com/hyperledger/fabric/devenv vagrant up
Go get coffee... this will take a few minutes. Once complete, you should
be able to
ssh into the Vagrant VM just created.
Once inside the VM, you can find the peer project under
$GOPATH/src/github.com/hyperledger/fabric. It is also mounted as
Building the fabric¶
Once you have all the dependencies installed, and have cloned the repository, you can proceed to build and test the fabric.
NOTE: Any time you change any of the files in your local fabric
update will be instantly available within the VM fabric directory.
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: 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.
NOTE to Windows 10 Users: There is a known problem with vagrant on
Windows 10 (see
vagrant up command fails it may be because you do not have
the Microsoft Visual C++ Redistributable package installed. You can
download the missing package at the following address:
