• 📦 Sample Data Loading: Automatically load sample datasets like travel-sample
• 🔐 Credential Management: Secure API key and database user management
• ⚙️ Configurable: Customize via environment variables or config files
• 🎨 Rich Output: Beautiful CLI with progress indicators and colored output

Installation

From PyPI

pip install couchbase-infrastructure

From Source

git clone https://github.com/couchbase/couchbase-infrastructure.git
cd couchbase-infrastructure
pip install -e .

Prerequisites

Before using this tool, you need:

1. Couchbase Capella Account: Sign up at cloud.couchbase.com
2. Management API Key: Generate from Capella Console → Settings → API Keys
   • Required permissions: Organization Admin
3. Organization ID (optional, will auto-detect if not provided)

Get Your Management API Key

1. Log in to Couchbase Capella Console
2. Navigate to Settings → API Keys
3. Create a new API key with Organization Admin permissions
4. Add your current IP address to the allowlist
5. Copy the API key (you'll only see it once!)

Quick Start

1. Set Environment Variables

Create a .env file:

# Required
MANAGEMENT_API_KEY=your_api_key_here

# Optional (will auto-detect if not provided)
ORGANIZATION_ID=your_org_id_here

# Optional customizations
PROJECT_NAME=Agent-Hub-Project
CLUSTER_NAME=agent-hub-cluster
DB_USERNAME=agent_app_user
EMBEDDING_MODEL_NAME=nvidia/nv-embedqa-mistral-7b-v2
LLM_MODEL_NAME=meta/llama-3.1-8b-instruct

2. Run Full Setup

couchbase-infra setup --env-file .env

This will:

1. ✅ Create or find a Capella project
2. ✅ Deploy a free tier cluster
3. ✅ Configure network access (allowlist)
4. ✅ Load travel-sample dataset
5. ✅ Create database credentials
6. ✅ Deploy embedding and LLM models
7. ✅ Create API key for models

CLI Usage

Test Connection

Test your API credentials:

couchbase-infra test-connection --env-file .env

Full Setup

Deploy complete infrastructure:

# Basic setup
couchbase-infra setup --env-file .env

# Skip AI model deployment
couchbase-infra setup --env-file .env --skip-models

# Skip sample data loading
couchbase-infra setup --env-file .env --skip-sample-data

# Set custom timeout (in seconds)
couchbase-infra setup --env-file .env --timeout 3600

List Resources

# List all projects
couchbase-infra list-projects

# List all clusters
couchbase-infra list-clusters

Get Help

# General help
couchbase-infra --help

# Command-specific help
couchbase-infra setup --help

Programmatic Usage

Use as a Python library in your own scripts:

from couchbase_infrastructure import (
    CapellaClient,
    CapellaConfig,
    create_project,
    create_cluster,
    deploy_ai_model,
)

# Load configuration from environment
config = CapellaConfig.from_env(".env")

# Initialize client
client = CapellaClient(config)
org_id = client.get_organization_id()

# Test connection
if client.test_connection(org_id):
    print("Connected successfully!")

# Create project
project_id = create_project(client, org_id, "My Project")

# Create cluster
cluster_id = create_cluster(client, org_id, project_id, "my-cluster", config)

# Deploy AI model
model_id = deploy_ai_model(
    client,
    org_id,
    "nvidia/nv-embedqa-mistral-7b-v2",
    "my-embedding-model",
    "embedding",
    config,
)

Configuration Options

All options can be set via environment variables:

Required

• MANAGEMENT_API_KEY: Your Capella Management API key

Optional

• ORGANIZATION_ID: Organization ID (auto-detected if not provided)
• API_BASE_URL: API base URL (default: cloudapi.cloud.couchbase.com)

Project & Cluster

• PROJECT_NAME: Project name (default: Agent-Hub-Project)
• CLUSTER_NAME: Cluster name (default: agent-hub-flight-cluster)
• CLUSTER_CLOUD_PROVIDER: Cloud provider (default: aws)
• CLUSTER_REGION: AWS region (default: us-east-2)
• CLUSTER_CIDR: CIDR block (default: 10.1.30.0/23)

Database

• DB_USERNAME: Database username (default: agent_app_user)
• SAMPLE_BUCKET: Sample bucket name (default: travel-sample)

AI Models

• EMBEDDING_MODEL_NAME: Embedding model (default: nvidia/nv-embedqa-mistral-7b-v2)
• LLM_MODEL_NAME: LLM model (default: meta/llama-3.1-8b-instruct)
• AI_MODEL_REGION: AI model region (default: us-east-1)
• EMBEDDING_MODEL_CPU: Embedding CPU cores (default: 4)
• EMBEDDING_MODEL_GPU_MEMORY: Embedding GPU memory GB (default: 24)
• LLM_MODEL_CPU: LLM CPU cores (default: 4)
• LLM_MODEL_GPU_MEMORY: LLM GPU memory GB (default: 48)

Network & Timeouts

• ALLOWED_CIDR: Allowed CIDR for cluster access (default: 0.0.0.0/0)
• RESOURCE_TIMEOUT: Timeout in seconds (default: no timeout)

Model Compute Sizes

Available compute sizes for AI models:

Size	CPU (vCPUs)	GPU Memory (GB)
Extra Small	4	24
Small	4	48
Medium	48	192
Large	192	320
Extra Large	192	640

Note: Extra Large may not be available in sandbox environments.

Troubleshooting

Authentication Failed (401)

1. Verify your API key is correct and not expired
2. Check if your current IP is in the API key allowlist
3. Ensure the API key has Organization Admin permissions

Get your current IP:

curl -s https://api.ipify.org

Free Tier Cluster Already Exists

Capella free tier allows only one cluster. The tool will automatically detect and use the existing cluster.

Timeout Issues

For slower provisioning, increase the timeout:

couchbase-infra setup --timeout 7200  # 2 hours

Or remove timeout completely (wait indefinitely) by not setting the --timeout flag.

Connection Issues

Test your connection first:

couchbase-infra test-connection
