Using the docker image [https://hub.docker.com/r/loadimpact/k6/](https://hub.docker.com/r/loadimpact/k6/).

There are no instructions, but a simple yml file is configured for GitLab.  
We are blocked by a message: \* level=error msg=“unknown command "sh" for "k6"”\*

```yml
loadtest:
  stage: performance-test
  image: loadimpact/k6
  only:
      - k6test
  script:
    - pwd
    - k6 run k6-performance/getSites.js
  cache: {}
  tags:
    - DOCKER
    - NOPROXY
    - CLOUD

Since the [`ENTRYPOINT`](https://docs.docker.com/engine/reference/builder/#entrypoint) of [k6’s Dockerfile is `k6`](https://github.com/loadimpact/k6/blob/master/Dockerfile#L10), you’d need to overwrite it in the GitLab CI file to be able to execute the commands you’ve specified in the `script` list. You can do it like this: [Run your CI/CD jobs in Docker containers | GitLab](https://docs.gitlab.com/ee/ci/docker/using_docker_images.html#overriding-the-entrypoint-of-an-image)

Pipeline still chokes with same output error.

```yml
loadtest:
  stage: performance-test
  image:
    name: loadimpact/k6
    entrypoint: ["k6"]
  only:
      - k6test
  script:
    - k6 run ./k6-performance/getSites.js
  cache: {}
  tags:

Set entrypoint as empty and that worked!

```yml
loadtest:
  stage: performance-test
  image:
    name: loadimpact/k6
    entrypoint: [""]
  only:
      - k6test
  script:
    - k6 run ./k6-performance/getSites.js
  cache: {}
  tags:
    - DOCKER
    - NOPROXY
