Custom k6 Load Tests in Containers

After covering the basics about k6 and ACIs, we still haven’t run our own tests. We saw that k6 can grab a JavaScript load test file from the web, and initiate requests to the endpoint(s) specified there. It means we can do the same and host a test file ourselves in our GitHub repo or anywhere else where it’s publicly accessible!

Before doing that though… Let’s see how to write these tests.

The brief anatomy of the k6 test scripts

The basic test provided by the team is only a few lines. This is the file we were using for the load tests in our Container Instance.

import http from "k6/http";

export default function () {
  const response = http.get("https://test-api.k6.io/");
