k3d

It is a lightweight wrapper to run k3s (Rancher Lab’s minimal Kubernetes distribution) in docker.

Great tool to work with Istio.

Requires Docker to use k3d.

Requires kubectl to interact with Kubernetes cluster.

curl -s https://raw.githubusercontent.com/k3d-io/k3d/main/install.sh | bash

Istioctl

Download and install Istio's client.

$ curl -L https://istio.io/downloadIstio | sh -
# Move the folder to /opt (Optional - may require sudo)
$ mv istio-1.24.2 /opt/istio-1.24.2
# Enter Istio package delivery directory (If package is istio-1.24.2)
$ cd /opt/istio-1.24.2
# Or add to .bash_profile if in WSL2
$ export PATH=$PWD/bin:$PATH

Install Istio on the cluster with the default profile.

You may Creating Cluster before installing Istio in the cluster.

Setup

Creating Cluster

k3d cluster create -p "8000:30000@loadbalancer" --agents 2

Bind the host 8000 with the cluster's 30000, because it is the port region to work with Kubernetes node ports.

k3d makes it easy to bind the host port into the Cluster. Other tools may not be that simple.

Configure Istio in k3d
