AlloyDB Basics

AlloyDB for PostgreSQL is a managed, PostgreSQL-compatible database service designed for enterprise-grade performance and availability. It utilizes a disaggregated compute and storage architecture to scale resources independently. It also provides AlloyDB AI, a collection of features that includes AI-powered search (vector, hybrid search, and AI functions), natural language capabilities, conversational analytics, and inference features like forecasting and model endpoint management to help developers build AI apps faster.

Quick Start

Enable the AlloyDB API:

gcloud services enable alloydb.googleapis.com --quiet

Create a Cluster:
```
gcloud alloydb clusters create my-cluster --region=us-central1 \
    --password=my-password --network=my-vpc \
    --quiet
```
Note: For production, we recommend using IAM database authentication instead of passwords. If passwords must be used, use secure secret management (e.g., Secret Manager) instead of passing passwords in cleartext.

Create a Primary Instance:

gcloud alloydb instances create my-primary --cluster=my-cluster \
    --region=us-central1 --instance-type=PRIMARY --cpu-count=2 \
    --quiet

Summary

AlloyDB Basics is a reference skill that teaches agents and developers how to manage AlloyDB clusters, instances, and backups using gcloud CLI, Terraform, client libraries, and MCP integrations. It provides structured documentation across six reference files covering core concepts, CLI usage, client connectors, Infrastructure-as-Code, security/IAM, and MCP server setup. The skill is read-only reference material with no destructive operations or file writes.

Use Cases

Set up an AlloyDB cluster using gcloud CLI
Configure AlloyDB with Terraform or Kubernetes Config Connector
Connect to AlloyDB using Python, Java, Go, or Node.js client libraries
Understand IAM roles and authentication options (IAM Auth vs built-in passwords)
Enable MCP server integration for AI-assisted AlloyDB operations
Learn about secure connectivity, encryption, and network configuration

Quality Notes

Strength: Clear structure with well-organized reference sections and logical progression from concepts to implementation.
Strength: Comprehensive coverage of authentication methods with explicit security recommendations (IAM Auth preferred, AlloyDB Connectors for secure access, warnings against public IP with open CIDR).
Strength: Multiple language examples (Python, Java, Go) with real, runnable code patterns.
Strength: Good use of tables for IAM roles and connectivity options.
Strength: Security section is thorough and emphasizes best practices (PSC over PSA, CMEK, VPC-SC, mTLS).
Weakness: Example code uses plaintext passwords ('my-password', 'alloydb-cluster') for brevity, but lacks callouts that these should always come from Secret Manager or environment variables in production. The Quick Start includes a helpful note about IAM auth and Secret Manager, but example code doesn't demonstrate this.
Weakness: No error handling guidance for common CLI or connector failures (e.g., network timeouts, authentication errors).
Weakness: Limited guidance on troubleshooting or debugging — skill references external docs but does not include diagnostic steps an agent should follow.
Weakness: No discussion of regional availability constraints or disaster recovery patterns.
Completeness: All six referenced files are present and cohesive. The skill is self-contained with links to external docs for deeper dives.
