How to use a kaniko based gitlab-runner to build a node.js image?

I am using a self hosted Gitlab repository to push my code. The code contains a Dockerfile that successfully creates a docker-image locally on my machine. My intention is now to automate this build process and integrate the docker-build in a Gitlab-Pipeline. I am bound to shared runners, so I can't integrate my own runners. And those runners aren't set up for simple docker-in-docker builds. I saw another project who uses the image gcr.io/kaniko-project/executor:debug for this problem. It successfully starts the build process of my Dockerfile, but after executing my first RUN argument it starts to add millions of artifacts to the layer, till it freezes.

I tried to replace the node:latest image with node:slim and it went one execution further in the Dockerfile. So I think that the problem is within the loading of the base-image. But I can't make out the reason.
Is Kaniko not able to download the base-image?
Do I need to provide the base-image in a different way?
Does someone have an example for a functioning kaniko pipeline that builds an image based on node?

Following part shows the logs of the runner.

You need the kaniko executor's debug image, which provides sh for gitlab-runner ci to execute

build:
  image: gcr.io/kaniko-project/executor:debug
  stage: build
  script:
    - executor --dockerfile=Dockerfile --context=$PWD --no-push

the reason for this is that if the image doesn’t allow to run scripts with CMD, the image will not work with the Docker executor. see ref gitlab runner's docker executor

For other docker push, you can follow the example to add extra configuration in your .gitlab-ci.yaml.
