Delegate not running
```

#### Resolution <a href="#resolution" id="resolution"></a>

Configure the delegate after setting the value for “POLL\_FOR\_TASKS” to “true” in yaml & change the image type for nodes while creating the cluster.

#### Diagnostic Steps <a href="#diagnostic-steps" id="diagnostic-steps"></a>

* Configure the Delegate after setting the value for “POLL\_FOR\_TASKS” to “true” in yaml. After this the container creation step will still fail with the following error message.

`Failed to pull image "GCR URL": rpc error: code = NotFound desc = failed to pull and unpack image "GCR URL": failed to unpack image on snapshotter overlayfs: failed to extract layer sha256:eada838fb7777f76b5776c6b4f1cd7694f86a49c39001c931ef04ca324472614: failed to get reader from content store: content digest sha256:9a960853d26c8ea4055375ba6debc7e6436c4ad0c69d97c890209bfb2b6cc212: not found Failed`

* To solve the above usecase change the image type for nodes while creating the cluster with **`Container-optimized OS with Docker`** instead of **`Container-optimized OS with Containerd`**
