GitLab CI leaves docker images on the system

I am running a GitLab runner in docker on my local system which creates a docker image of the repository and runs some tests. This is my gitlab-ci.yml:

variables:
  GIT_SUBMODULE_STRATEGY: recursive

stages:
  - build
  - test

build image:
  stage: build
  image: docker:20.10.16
  services:
    - docker:dind
  script:
    - docker login -u $CI_REGISTRY_USER -p $CI_REGISTRY_PASSWORD $CI_REGISTRY
    - docker pull $CI_REGISTRY_IMAGE
    - docker build --cache-from $CI_REGISTRY_IMAGE -t $CI_REGISTRY_IMAGE .
    - docker push $CI_REGISTRY_IMAGE

run-tests:
  stage: test
  image: $CI_REGISTRY_IMAGE
  script:
    - source /app/venv/bin/activate && pytest .

The problem is that this leaves docker images with a "none" tag that end up occupying a lot of storage as you can see from the image. list of images left created by the gitlab runner

How can I avoid this? Is there an option to add in gitlab-ci.yml such that the container used is deleted after the last stage is completed?

I suggest clearing the docker cache as well as clearing old build images as per the official documentation.

/usr/share/gitlab-runner# ./clear-docker-cache
/usr/share/gitlab-runner# docker system prune
