Module 7: Production Considerations

Overview

Now that you can build, test, and debug operators (Module 6), it’s time to prepare them for production. This module covers packaging, distribution, security, high availability, and performance optimization - all essential for running operators in production environments.

Duration: 6-7 hours
Prerequisites:

Completion of Module 1: Kubernetes Architecture Deep Dive
Completion of Module 2: Introduction to Operators
Completion of Module 3: Building Custom Controllers
Completion of Module 4: Advanced Reconciliation Patterns
Completion of Module 5: Webhooks and Admission Control
Completion of Module 6: Testing and Debugging
Understanding of container images and Helm

Learning Objectives

By the end of this module, you will:

Package operators for distribution (images, Helm charts, OLM bundles)
Configure proper RBAC and security
Implement high availability with leader election
Optimize performance and scalability
Understand production deployment best practices

Module Structure

Prerequisites Check

Before starting, ensure you’ve completed:

✅ Module 6: Operator with tests and observability
✅ Have a working operator from previous modules
✅ Understand container images and Docker
✅ Basic understanding of Helm charts

If you haven’t completed Module 6, start with Module 6: Testing and Debugging.

What You’ll Build

Throughout this module, you’ll prepare your Database operator for production:

Container image for distribution
Helm chart for easy deployment
Proper RBAC configuration
High availability setup
Performance optimizations

Setup

Before starting this module:

Have your Database operator from Module 3/4/5/6:
- Should have a working operator
- Tests should be passing
- Ready for production deployment
Ensure development environment is ready:
```
./scripts/setup-dev-environment.sh
```
Have access to a container registry:
- Docker Hub, GitHub Container Registry, or private registry
- For local testing, you can use kind’s image loading

Hands-on Labs
