I am getting below error while pulling image from Artifactory repository. I am using Gitlab Runner to set the configuration

Waiting for pod sai/runner-dan3u2t-project-9879-concurrent-0zdmgf to be running, status is Pending
	ContainersNotReady: "containers with unready status: [build helper svc-0]"
	ContainersNotReady: "containers with unready status: [build helper svc-0]"

WARNING: Failed to pull image with policy "": image pull failed: Back-off pulling image "aie-docker-dev-mydockerrepo/python:3.6-strech"
ERROR: Job failed (system failure): prepare environment: waiting for pod running: pulling image "aie-docker-dev-mydockerrepo/python:3.6-strech": image pull failed: Back-off pulling image "aie-docker-dev-mydockerrepo/python:3.6-strech"

Below is the value file I used to create gitlab runner

gitlabUrl: 'https://gitlab.bayer.com/'
runnerRegistrationToken: **********
rbac:
  create: false
  serviceAccountName: ************
serviceAccount.name: *************


resources:
  limits:
    memory: 16000Mi
    cpu: 2000m
  requests:
    memory: 16000Mi
    cpu: 2000m

runners:
  privileged: true

Should i make change to values file or gitlab files to get this corrected.Any idea ?
