fabric-devenv

Vagrant environment to help get started with Hyperledger Fabric.

Ingredients

You'll need to stock your machine with all these healthy ingredients if you don't have them already:

VirtualBox
Vagrant
- Note: fabric-devenv requires Vagrant 2.0.3 or greater
Git

Method

To configure a development environment for Hyperledger Fabric 2.2.0, run the following commands:

git clone https://github.com/jt-nti/fabric-devenv.git
cd fabric-devenv
vagrant up

When the development environment has finished cooking, log in using:

vagrant ssh

Serving suggestion

Now that you have a working development environment, the VSCode Remote Development capability is a great way to use it.

After installing the extension, use the 'Remote-SSH: Connect to Host...' VSCode command to connect to the development environment.

Note: You'll need to pick Configure SSH Hosts... the first time to add a host for the development environment to your SSH configuration file. To get the required SSH configuration, run:

vagrant ssh-config

Alternative toppings

To install specific versions of Fabric, set a HLF_VERSION environment variable before running vagrant up.

For example, to install the 2.4.0 Beta version of Fabric use:

HLF_VERSION=2.4.0-beta vagrant up

Or on Windows:

set HLF_VERSION=2.4.0-beta
vagrant up

Supported HLF_VERSION values:

Specific 1.4, 2.0, 2.1, 2.2, 2.3, or 2.4 version numbers

Cooking tips

Extra dishes

If you want to set up several VMs with different versions, or for different purposes, you can clone the fabric-devenv repository into different directories. For example,

git clone https://github.com/jt-nti/fabric-devenv.git fabric-tutorial

Or simply copy an existing clone. The different directory names should show up in the VirtualBox UI after running vagrant up if you need to update the VM settings for any of your environments.

Larger portions

The development environment has an extra 20GB disk on top of the normal storage. The opt and home directories have 5GB each, leaving another 10GB if you run out of storage.

The following commands will show disk usage and volume group information respectively:

df
sudo vgdisplay -v

For example, if they show that the home directory is full and there is still enough unallocated space, you can increase the size using these commands:

sudo lvextend -L +5G /dev/vagrant/home
sudo resize2fs /dev/vagrant/home

Clearing up

When you've finished with a development environment you can suspend it using vagrant suspend and resume later using vagrant up.

Alternatively, if you've finished with Fabric or want to start again, vagrant destroy will completely remove the virtual machine and the extra disk.

Known problems

The Vagrant cachier plugin appears to cause problems with the latest version of Vagrant.
