Hyperledger Fabric Blockchain

Running the network

You should be in the root repository directory, i.e. ~/path/to/blockchain.

./setup-fablo.sh
./fablo.sh prune
./fablo.sh generate
./fablo.sh up

Prerequisites

• bash
• curl
• docker
• docker-compose
• fablo
• jq

Troubleshooting

Potential problems with docker-compose

Recent installations of docker have deprecated docker-compose in favor of docker compose, but shell scripts that are used in Hyperledger Fabric and Fablo (the generation tool) still use docker-compose.

In your terminal, check if you have docker-compose:

command -V docker-compose

If you get docker-compose not found, see the next section for a patch.

Patching docker-compose

You can patch this docker-compose by doing the following in your terminal:

if [ -f /usr/bin/docker-compose ]; then
  printf %s\\n 'docker-compose already exists.'
else
  sudo printf '%s\n%s' '#!/bin/sh' 'docker compose "$@"' > /usr/bin/docker-compose
  chmod +x /usr/bin/docker-compose
  USER_CURRENT=$(whoami)
  sudo chown "$USER_CURRENT":"$USER_CURRENT" /usr/bin/docker-compose
  unset USER_CURRENT
fi

Root permissions for docker socket

Run the following your terminal:

sudo usermod -aG docker "$USER"

Then, log out and log back in.

Docker daemon

Run the following your terminal:

sudo systemctl enable --now docker.service docker.socket

This starts docker now and also starts docker by default on boot.
