Scenario ica-trf-006 · about 8 minutes · 8 points · 4 grader checks

Use VirtualService fault injection to delay test traffic and fail half of the remaining requests.

  • abort
  • virtualservice

What you will practise

  • Inject a fixed delay for matching requests
  • Abort a percentage of requests with an HTTP status
  • Verify fault injection 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-006

Task

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

Istio is installed. Namespace "faults" (in the mesh) runs the Service "ratings" (port 8000) and the Deployment "curl". Create a VirtualService "ratings" in "faults" for the host "ratings" with two HTTP routes, both sending traffic to "ratings": 1. Requests with the header "x-test: delay" are delayed by a fixed 2 seconds (all of them) and are not aborted. 2. All other requests are aborted with HTTP status 503 in 50 % of the cases.

Grading runs locally: 4 state checks read your cluster when you submit; the scenario passes when every check passes. Hints, the reference solution and the check definitions are available only inside the CLI, not on this page.
