When running with the following config:

apiVersion: k6.io/v1alpha1
kind: K6
metadata:
  name: one-load-test
spec:
  parallelism: 1
  arguments: --out statsd
  script:
    localFile: /app/tests/load/scriptv1.js
  runner:
    image: some.custom.repo:latest
    serviceAccountName: k6-runner

I am presented with the following error:

This seems like it may be a regression of localFile feature is broken · Issue #111 · grafana/k6-operator · GitHub

@one-miles, how exactly are you using the k6-operator? From what I can see, this probably is not a regression, it just seems like localFile fix hasn’t been released in a stable release yet :disappointed:

So you probably have to either git pull the latest version of the k6-operator repo locally or use one of the docker image versions that are based on the recent main repo commits: https://github.com/grafana/k6-operator/pkgs/container/operator

I’ll ping the k6-operator maintainer next week to maybe release a new version, since they are currently on vacation and I am very out of touch and not sure how to do that myself or if there are any blockers for it… :sweat_smile: Sorry about that and hope this advice helps.

And if the latest main version of the k6-operator still results in the same problems, please comment here or in the issue and we’ll reopen it.

Hey @ned thanks for the response!

I am pulling (and building) from the latest main. FWIW, there is another report of this in the k6 #community-discussion slack channel as well.

Thanks, I’ve reopened the issue, but I don’t understand the problem well enough to fix it on my own quickly, sorry.

Hi @one-miles,
I was unable to repeat this error with the latest from main: could it be that the image just wasn’t being pulled or some cache was involved? Just in case, I’ve built a new latest and also pushed an RC release so you can deploy it like this now:

IMG=ghcr.io/grafana/operator:controller-v0.0.8rc1 make deploy

Please try it out and let me know if the issue persists.
