Software installation for Debian Linux

# Install required software.
sudo apt-get update
sudo apt-get install -y git uidmap docker docker-compose dbus-user-session fuse-overlayfs slirp4netns

# Enable rootless use of docker.
curl -fsSL https://get.docker.com/rootless | sh

# Reboot.
sudo shutdown -r now

Deploy Marlowe Runtime

# Set environment variables required by docker.
export PATH=$HOME/bin:$PATH
export DOCKER_HOST=unix://$XDG_RUNTIME_DIR/docker.sock

# Clone the Marlowe starter kit.
git clone https://github.com/input-output-hk/marlowe-starter-kit -b [email protected]
cd marlowe-starter-kit

# Select the network.
export NETWORK=mainnet

# Start Marlowe Runtime.
docker-compose up -d

# Check to see that services have come up successfully.
docker-compose ps

# View the logs.
docker-compose logs --timestamp --tail 200 --follow

Create a Nix environment

Install NixOs.

sh <(curl -L https://nixos.org/nix/install) --daemon

Add your account as a trusted user.

sudo sh -c "echo trusted-users = $USER >> /etc/nix/nix.conf"

Restart the Nix daemon.

sudo systemctl restart nix-daemon.service

Close the current shell/terminal session and enter a new one.

Enter a development environment

The Marlowe Runtime development environment has tools such as marlowe-runtime-cli and cardano-cli installed.

nix develop --extra-experimental-features nix-command --extra-experimental-features flakes

Launch a Jupyter notebook server

The Jupyter notebook kernel for Marlowe contains tools such as marlowe-runtime-cli and can be used to run the starter kit lessons.

nix run --extra-experimental-features nix-command --extra-experimental-features flakes

Use a web browser to visit the URL for the Jupyter notebook server.
