What you will practise

  • Define subsets for two versions
  • Split traffic with weighted destinations
  • Observe a weighted split from a client

Start this lab

With the CLI installed and signed in, this command provisions a single node cluster on your Mac, applies the scenario setup and prints the task below.

goldenkube start ica-trf-003

Task

The task text exactly as the CLI shows it. Solve it on the cluster, then run goldenkube submit.

Istio is installed. Namespace "shift" (in the mesh) runs the Service "helloworld" (port 5000) backed by the Deployments helloworld-v1 and helloworld-v2 (pod labels version=v1 and version=v2). Shift traffic for "helloworld" so that 80 % of all requests go to v1 and 20 % go to v2: 1. Create a DestinationRule "helloworld" in "shift" with the subsets "v1" and "v2" selected by the label "version". 2. Create a VirtualService "helloworld" in "shift" for the host "helloworld" with one weighted route (v1: 80, v2: 20).
