The Istio Certified Associate, ICA is a challenging and practical hands on exam. To help learn a capability I like the idea of an exam based goal, it’s achievable and ensures I attain a strong understanding of the system. Building a question and problem solving routine I used the following workflow, to methodically tackle each question. I found the routine helpful as it developed muscle memory and was one less thing to have to remember.

Overview The environment is managed by a single script, manage-cluster.sh, which automates the creation, configuration, and teardown of the entire stack. This setup is ideal for testing and developing with Istio service mesh on a local machine. The script handles the following: Kind Cluster Creation: Sets up a multi-node Kubernetes cluster.

It uses Rancher Desktop, Minikube, and a custom Go application to demonstrate a real-world CloudEvents workflow. Source available from github.com. The core of this setup is a robust shell script that automates the creation and destruction of a fully configured Knative cluster.

These efficiencies will manifest as either more output from existing developers or fewer developers required to achieve the same task, thus increasing productivity. As every casual economics amateur knows, the main way to increase workers’ productivity is by giving them more and better machines to work with.

The entire workflow is automated via a single shell script (provisioner.sh) that sets up a local Kubernetes kind cluster, installs Crossplane, configures the AWS provider, and provisions an S3 bucket. This setup runs locally within Rancher Desktop or any other container runtime that supports kind. Uses the example from AWS Quickstarts, with additional automation.
