Chaos in Containers - Unleashing Resilience

Your IaC tools are just one-shot executors, not true management systems. Learn how to use Kubernetes as a universal control plane to finally eliminate configuration drift.

#1about 2 minutes

The limitations of using pipelines for everything

Relying on numerous CI/CD pipelines for infrastructure management creates complexity and is not ideal for resources with a lifecycle.

#2about 3 minutes

The evolution from scripts to infrastructure as code

Infrastructure management evolved from manual shell scripts to configuration management and finally to API-driven Infrastructure as Code tools like Terraform.

#3about 1 minute

Understanding configuration drift with IaC tools

Infrastructure as Code tools are one-shot executors that don't continuously manage state, leading to configuration drift where reality diverges from code.

#4about 1 minute

Using Kubernetes as an extensible control plane

Kubernetes can be used as a universal control plane because its orchestration capabilities are extensible beyond its native resources.

#5about 3 minutes

Managing external resources with Crossplane and Kubernetes

Crossplane extends Kubernetes to manage external cloud resources through providers and custom composite resources, enabling continuous reconciliation to prevent drift.

#6about 2 minutes

Implementing a GitOps workflow with Argo CD

Use a GitOps operator like Argo CD to automatically sync resource definitions from a Git repository to the Kubernetes control plane for declarative management.

#7about 6 minutes

Demo of provisioning a full stack with Crossplane

A practical demonstration shows how a Git commit triggers Argo CD and Crossplane to provision a Kubernetes cluster, an API Gateway, and a DynamoDB table.

#8about 3 minutes

Solving the control plane bootstrapping problem

Overcome the initial chicken-and-egg problem by using a temporary Kubernetes cluster to provision the permanent control plane, then migrating the state to make it self-managing.

Q&A on recovery, versioning, and Terraform migration

The Q&A session covers topics like resource recovery after a control plane failure, schema versioning, and strategies for migrating from Terraform to Crossplane.
