⚠️ This is a proof of conceptAs this is a proof of concept, it won't be supported by the k6 team. It may also break in the future as xk6 evolves. USE AT YOUR OWN RISK! Any issues with the tool should be raised here.
Build
To build a k6 binary with this extension, first ensure you have the prerequisites:
- Go toolchain
- Git
Then:
- Download
xk6:
$ go install go.k6.io/xk6/cmd/xk6@latest- Build the binary:
$ xk6 build --with github.com/grafana/xk6-chaos@latestExample
import chaos from 'k6/x/chaos';
import { Pods } from 'k6/x/chaos/k8s';
export default function () {
console.log(`Running grafana/xk6-chaos@${chaos.version}.`);
const p = new Pods();
console.log(
`There are currently ${p.list().length} pods in the default namespace.`
);
killPod(p);
console.log(
`There are now ${p.list().length} pods in the default namespace.`
);
}
function killPod(p) {
const victim = p.list()[0];
console.log(`Killing pod ${victim}`);
p.killByName('default', victim);
}Result output:
