BLUF: This video walks through installing Istio 1.18.2 on a Kubernetes cluster using the istioctl CLI, tailored for the ISTIO certification exam 0:03.
Key Takeaways:
• Istio can be installed via istioctl CLI or Helm; the CLI is demonstrated and recommended for exam preparation 0:44
• The demo profile is used as it includes core components without the resource-heavy ambient mesh, making it ideal for exam environments 3:35
• Namespace labeling (e.g., istio-injection=enabled) is required to enable sidecar proxies in application pods 5:31
• Manual sidecar injection can be performed using istioctl kube-inject on specific workloads without namespace-wide labeling 7:05
• The istioctl analyze command is critical for validating configuration syntax and identifying errors, especially during exams 9:14
This hands-on tutorial provides essential, exam-focused steps for installing and configuring Istio in a Kubernetes environment.

[Music] Hey there, I'm Anthony from CodeCloud. Are you ready to get your ISTTO running on your Kubernetes cluster? In this hands-on demo, I'll show you how to install ISTTO using the ISTTO CLI. Let's get started and be sure to subscribe and like at the end if you find this useful. In order to install ISTTO, you need a running Kubernetes cluster. You can use uh Amazon EKS uh GKE the Google's or even Azure's um AKS. If you want to do a local environment, you can use either kind or mini cube. But you do need a running Kubernetes cluster. There are two options when it comes to installing STTO. You can use the STTO ctl which is CLI tool or you can use uh Helm. We will review both ways as you will be asked to install STTO and it could be using either option. I'm going to go with the ISTOCTL, but…
