Network Setup

This guide explains how to set up Bacalhau networks for various deployment scenarios, from development environments to production deployments.

Introduction

Bacalhau's architecture consists of two primary node types:

• Orchestrator nodes that schedule and manage jobs

• Compute nodes that execute workloads

Compute nodes connect to orchestrators, but don't need to be reachable by orchestrators or other compute nodes, making deployment simpler.

Getting Started with Bacalhau

Choose the setup option that best matches your needs:

Setup Option	Best For	Key Benefit
Expanso Cloud	Production deployments	Fully managed orchestrator service
DevStack	Development & testing	Quick local setup with minimal configuration
Self-Hosted Network	Custom infrastructure requirements	Complete control over all components

Option 1: Expanso Cloud

(Recommended for Production)

Expanso Cloud provides a managed orchestrator service, eliminating the need to set up and maintain your own orchestrator.

Setting Up with Expanso Cloud

1. Sign up for Expanso Cloud to receive:

   • An orchestrator endpoint

   • Authentication credentials

   • A configuration file

2. Create a configuration file (or use the one provided):

# config.yaml
Compute:
  Enabled: true
  Orchestrators:
    - <orchestrator-endpoint>
  Auth:
    Token: <auth-token>
  TLS:
    RequireTLS: true

1. Start your compute node:

bacalhau serve --compute -c config.yaml

1. Submit jobs to the Expanso Cloud orchestrator:

bacalhau docker run \
  --api-host <expanso-endpoint> \
  ubuntu:latest \
  -- echo "Hello from Expanso Cloud!"

This is the simplest way to run a Bacalhau network with minimal setup and maintenance.

Option 2: Self-Hosted Network

If you need to host your own orchestrator, follow these steps for a custom deployment.

Setting Up an Orchestrator Node

On your designated orchestrator machine:

# Start an orchestrator-only node
bacalhau serve --orchestrator

Take note of this machine's IP address or hostname - you'll need it to connect compute nodes.

Adding Compute Nodes

On each machine that will execute jobs:

# Start a compute-only node connected to your orchestrator
bacalhau serve --compute -c Compute.Orchestrators=<orchestrator-ip>:4222

Replace <orchestrator-ip> with the actual IP address or hostname of your orchestrator.

Verifying Your Cluster

Check that all nodes are connected:

# List all nodes in your network
bacalhau node list

You should see your orchestrator and all compute nodes listed.

Note: The setup described above creates an open network suitable for testing in trusted environments. For securing your network, refer to the Security Best Practices in the Reference section.

Option 3: DevStack

DevStack provides a pre-configured local environment perfect for development and testing.

# Launch a complete development environment
bacalhau devstack

This pre-configures a transient orchestrator and compute nodes by default, giving you a complete environment for testing with minimal setup.

You can submit jobs to your DevStack just like any other Bacalhau network:

bacalhau docker run ubuntu:latest -- echo "Hello from DevStack!"

Alternative Setup Methods

These methods provide additional ways to set up Bacalhau for specific use cases.

Single Hybrid Node

For the simplest local setup, you can run a single node that acts as both orchestrator and compute:

# Launch a combined orchestrator and compute node
bacalhau serve --orchestrator --compute

This starts Bacalhau in "hybrid mode" where:

• The orchestrator handles job scheduling

• The compute service executes containers

• Both components run in the same process

This option is useful for initial testing or for very small deployments.

Docker Deployment

Run Bacalhau in Docker for easier management:

# Run an orchestrator node
docker run -p 4222:4222 ghcr.io/bacalhau-project/bacalhau:latest serve --orchestrator

# Run a compute node using Docker-in-Docker
docker run --privileged -p 4222:4222 \
  ghcr.io/bacalhau-project/bacalhau:latest-dind \
  serve --compute -c Compute.Orchestrators=<orchestrator-ip>:4222

The bacalhau:latest-dind image includes Docker-in-Docker capabilities required for compute nodes.

Docker Compose Setup

For a quick multi-node setup, Bacalhau provides Docker Compose examples that create a complete network suitable for testing:

1. Clone Network Setups Repository Clone the repository containing the network setups:

   git clone https://github.com/bacalhau-project/bacalhau-network-setups.git

2. Navigate to a Specific Setup Change directory to your desired setup under docker-compose:

   cd bacalhau-network-setups/docker-compose/<setup-name>

3. Start the Network Use Docker Compose to bring up the network:

   docker compose up

These setups enable deployment and testing of Bacalhau across multiple nodes, including an orchestrator and persistent data storage.
