Setting Up Your Environment Securely 🌟

Welcome to Module 2! In this module, you’ll set up the foundational pieces that will enable seamless synchronization between your Amazon RDS and Neon databases using GitHub Actions. This involves configuring your GitHub repository, setting up OIDC authentication with AWS, and creating a workflow for automatic data synchronization.

Let’s dive in and learn how these components fit together to power your workshop environment!

🧐 What is OIDC?

OIDC (OpenID Connect) is an identity layer built on top of OAuth 2.0. It allows applications (like GitHub Actions) to securely authenticate with identity providers (like AWS). In this workshop, OIDC helps GitHub Actions assume an AWS role without requiring long-term access keys.

Why OIDC?

  • No need for access keys: It eliminates the need to store AWS credentials in GitHub Secrets, reducing the risk of exposure.
  • Secure and dynamic: GitHub Actions generates short-term tokens that AWS verifies, ensuring a secure connection.
  • Simplified setup: AWS manages permissions dynamically based on the role you configure.

🛠️ Key Steps in this Module

This module is broken into several parts to guide you through setting up your environment:

1️⃣ Setting Up Your GitHub Repository

You’ll create a GitHub repository that will host the workflows and scripts necessary for database synchronization.

Why this matters: A centralized repository ensures that your synchronization logic is version-controlled and easy to update.

2️⃣ Configuring OIDC Authentication

You’ll deploy a pre-built CloudFormation template that establishes the trust relationship between GitHub Actions and AWS. This will allow GitHub Actions to assume an IAM role and access AWS services securely.

Key takeaway: This step is the backbone of secure and seamless integration between GitHub and AWS.

3️⃣ Adding Secrets to GitHub

You’ll configure sensitive information like database connection strings and AWS region details as GitHub Secrets. These secrets are securely stored and accessed by workflows during runtime.

Why this is important: Secrets enable your workflows to interact with AWS and databases without exposing sensitive information in plain text.

4️⃣ Creating Your GitHub Actions Workflow

Finally, you’ll create a GitHub Actions workflow that uses OIDC authentication to:

  • Dump your RDS database
  • Restore the data to a Neon database
  • Automate this process nightly

End goal: A fully automated data synchronization pipeline for a fresh and reliable development environment!

💡 Concepts to Understand Before Moving On

Here are some important terms and tools you’ll encounter in this module:

🔒 GitHub Secrets

A secure way to store sensitive data like database connection strings and AWS credentials. You’ll configure secrets like:

  • PROD_DATABASE_URL: Connection string for your RDS database.
  • DEV_DATABASE_URL: Connection string for your Neon database.

☁️ CloudFormation

AWS CloudFormation automates the creation of resources like IAM roles and trust policies. You’ll use it to set up OIDC authentication.

⚙️ GitHub Actions

A powerful tool for automating CI/CD workflows. In this workshop, GitHub Actions will:

  • Authenticate with AWS using OIDC.
  • Dump data from RDS.
  • Restore data to Neon.

📅 Cron Scheduling

A time-based scheduler that allows workflows to run automatically. You’ll use a daily schedule to keep your Neon database in sync with RDS.

🎯 Learning Outcomes

By the end of this module, you will:

  • Understand how OIDC authentication works and its benefits for secure integrations.
  • Configure GitHub Secrets to securely manage sensitive information.
  • Deploy a CloudFormation stack to set up OIDC authentication.
  • Create and test a GitHub Actions workflow for database synchronization.
