Spacelift Terraform Management

Use Spacelift for collaborative Terraform management with policy-as-code, drift detection, and approval workflows. This guide provides practical setup instructions and production-ready configurations for implementing this on your VPS infrastructure.

Installation and Setup

# Install the tool on your VPS
# Follow the official installation guide for your distribution
# Most tools support Docker-based deployment for easy setup

# Quick start with Docker
docker pull spacelift-terraform-management:latest
docker run -d --name spacelift-terraform-management -p 8080:8080 spacelift-terraform-management:latest

# Or install natively
curl -fsSL https://install.example.com | sh

Core Configuration

The primary configuration covers collaborative workflows and policy-as-code with OPA setup. These form the foundation of a working deployment:

# Primary configuration file
# Adjust these settings based on your environment

# Enable core features
collaborative workflows:
  enabled: true
  interval: 300  # seconds

# Configure policy-as-code with OPA
policy-as-code with OPA:
  enabled: true
  targets:
    - production
    - staging

# Authentication and security
auth:
  type: token
  token_file: /etc/secrets/api-token

drift detection dashboards Configuration

Setting up drift detection dashboards is essential for production reliability:

# Configure drift detection dashboards
# This ensures your setup handles production workloads correctly

# Key settings for drift detection dashboards:
# 1. Set appropriate resource limits
# 2. Configure health checks
# 3. Enable logging and monitoring
# 4. Set up backup and recovery

resources:
  limits:
    cpu: "2"
    memory: "2Gi"
  requests:
    cpu: "500m"
    memory: "512Mi"

healthCheck:
  enabled: true
  interval: 30s
  timeout: 10s

approval workflows Integration

Integrating approval workflows provides visibility into system health and performance:

# Set up monitoring and alerting
# Prometheus metrics endpoint
metrics:
  enabled: true
  port: 9090
  path: /metrics

# Alert rules
alerts:
  - name: HighErrorRate
    condition: error_rate > 0.05
    duration: 5m
    severity: critical
    notify:
      - slack
      - email

# Dashboard integration
# Import provided Grafana dashboards for visual monitoring

cost estimation

• Security: Always use TLS for communication, rotate credentials regularly, and follow the principle of least privilege
• High availability: Run multiple instances behind a load balancer for production workloads
• Backup: Regularly back up configuration and state data
• Updates: Keep the tool updated for security patches and new features
• Documentation: Maintain runbooks for common operations and incident response
