Managed runner not able to pull image from docker hub

Summary

I am trying to run docker inside docker to build docker image using managed runner, while doing so I am trying to pull image from docker hub. It fails to pull image from docker hub

Steps to reproduce

• You need a gitlab repository which host your code
• .gitlab-ci.yml file with job definition
• docker image tag
• commit to repository

.gitlab-ci.yml

build_image:
  image: docker:20:10:17
  services:
    - docker:20.10.17-dind
  variables:
   DOCKER_TLS_CERTDIR: "/certs"
  before_script:
    - docker login -u $REGISTRY_USER -p $REGISTRY_PASS
  script:
    - docker build -t $IMAGE_NAME:$IMAGE_TAG .
    - docker push $IMAGE_NAME:$IMAGE_TAG

Actual behavior

• The job fails with an error -> ERROR: Job failed: failed to pull image "docker:20:10:17" with specified policies [always]: invalid reference format (manager.go:235:0s)

Expected behavior

Successful job run with docker image pushed to my GitLab repository
