  1. Verify ACR Service Availability
     • Ensure that the Azure ACR service is operational in the Azure region where your registry is hosted. Check the Azure status page:
     Azure Status (<https://status.azure.com/>)
     • If there are ongoing outages in your region, this could be the cause.
  2. Check ACR Permissions
     • Ensure the credentials used for pulling the image have the correct permissions.
     ◦ If using a service principal, confirm it has the AcrPull role assigned.
     ◦ If using a managed identity, check its assigned roles.
     • Verify credentials by running:If it logs in successfully, credentials are likely not the issue.
     `az acr login --name <ACR_NAME>`
  3. Validate Image Existence
     • Confirm that the image and tag you are trying to pull exist in the Azure ACR:Example:
     `az acr repository show-tags --name myacr --repository myimage`
     `az acr repository show-tags --name <ACR_NAME> --repository <IMAGE_NAME>`
  4. Check Docker Daemon Logs
     • Inspect Docker logs for additional details on the error:Look for any errors or network-related issues during the pull operation.
     `sudo journalctl -u docker`
  5. Clear Docker Cache
     • Sometimes, Docker's cache can interfere with operations. Clear the cache:
     `docker system prune -a`
  6. Pull the Image Manually with Debugging
     Enable detailed output during the pull operation: 
     `docker --debug pull <ACR_NAME>.azurecr.io/<IMAGE_NAME>:<TAG>`
     This structured approach should help identify and resolve the problem effectively.
