The following prerequisites are required to run a Docker-based Fabric test network on your local machine.
For macOS, we recommend using Homebrew to manage the prereqs.
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)" brew --version # => Homebrew 2.5.2
The Xcode command line tools will be installed as part of the Homebrew installation. Once Homebrew is ready, installing the necessary prerequisites is very easy:
Install the latest version of git if it is not already installed.
brew install git git --version # => git version 2.23.0
Install the latest version of cURL if it is not already installed.
brew install curl curl --version # => curl 7.64.1 (...)
Install the latest version of Docker Desktop if it is not already installed.
Since Docker Desktop is a UI application on Mac, use
cask to install it.
brew cask install --appdir="/Applications" docker
brew install --cask --appdir="/Applications" docker
Docker Desktop must be launched to complete the installation so be sure to open the application after installing it:
Once installed, confirm the latest versions of both
docker-compose executables were installed.
docker --version # => Docker version 19.03.12, build 48a66213fe docker-compose --version # => docker-compose version 1.27.2, build 18f557f9
Note: Some users have reported errors while running Fabric-Samples with the Docker Desktop
gRPC FUSE for file sharingoption checked. Please uncheck this option in your Docker Preferences to continue using
osxfs for file sharing.
Optional: Install the latest Fabric supported version of Go if it is not already installed (only required if you will be writing Go chaincode or SDK applications).
brew install firstname.lastname@example.org go version # => go1.21.4 darwin/amd64
Linux (Ubuntu/Debian based distro)¶
sudo apt-get install git curl docker-compose -y # Make sure the Docker daemon is running. sudo systemctl start docker # Add your user to the Docker group. sudo usermod -a -G docker <username> # Check version numbers docker --version docker-compose --version # Optional: If you want the Docker daemon to start when the system starts, use the following: sudo systemctl enable docker
Optional: Install the latest version of Go (only required if you will be writing Go chaincode or SDK applications).
Both the Fabric documentation and Fabric samples rely heavily on a
bash environment. The recommended
path is to use WSL2 (Windows Subsystem for Linux version 2) to provide a native Linux environment and then you can follow the Linux prerequisites section (excluding the Linux Docker prerequisite as you already have Docker Desktop) and install them into your WSL2 linux distribution.
WSL2 may not be installed by default; you can check and install WSL2 by going into “Programs and Features”, clicking on “Turn Windows features on or off” and ensuring that both “Windows Subsystem For Linux” and “Virtual Machine Platform” are selected.
Next you will need to install a Linux distribution such as Ubuntu-20.04 and make sure it’s set to using version 2 of WSL. Refer to Install WSL for more information.
Finally, you need to ensure Docker Desktop has integration enabled for your distribution so it can interact with Docker elements, such as a bash command window. To do this, open the Docker Desktop gui and go into settings, select
Resources and them
WSL Integration and ensure the checkbox for enable integration is checked. You should then see your WSL2 linux distribution listed (if you don’t then it is probably because it is still a WSL1 distribution and needs to be converted to WSL2) and you can then toggle the switch to enable integration for that distro. Refer to Docker Desktop WSL2 backend for more information
Microsoft VS Code (Optional)¶
Microsoft VS Code provides an IDE that has tight integration with WSL2 Linux Distibutions. Search the Microsoft Marketplace in VS Code for the Remote Development extension pack for more information. This pack includes, among other things, the
Remote - WSL extension and the
Remote - Containers extension.
Git For Windows (Optional)¶
Although not required, if you do decide to install Git on Windows and manage the Fabric repositories natively (as opposed to within WSL2 and its Git installation), then make sure you configure Git as follows:
Update the following
git config --global core.autocrlf false git config --global core.longpaths true
You can check the setting of these parameters with the following commands:
git config --get core.autocrlf git config --get core.longpaths
These output from these commands should be false and true respectively.
