configuration. Here’s a step-by-step approach to rectify this issue:
1. Ensure Correct Indentation: YAML is very sensitive to indentation. Verify that the indentation under worker:
is correct. It appears correctly indented in your example, but it's worth double-checking.
2. Correct Config Format: Verify that the provided format aligns well with the expected structure in the Helm template files.
3. Work Pool Creation: Confirm that the work pool default-work-pool
exists and is correctly set up. You can do this via the Prefect CLI:
bash
prefect work-pool create default-work-pool
4. Helm Values File: Simplified values example for reference:
yaml
worker:
cloudApiConfig:
accountId: 3da
workspaceId: 396
apiKeySecret:
name: prefect-api-key-shiftsmart-secret
key: key
config:
workPool: default-work-pool
replicaCount: 6
resources:
limits:
cpu: 1000m
memory: 1Gi
requests:
cpu: 100m
memory: 256Mi
fullnameOverride: base-prefect-workerv2
5. Inspect Template: Check the Helm template file deployment.yaml
at line 70:
yaml
{{- if .Values.worker.config.workPool -}}
...
{{- else -}}
{{- fail "A Work Pool Name is required (worker.config.workPool)" -}}
{{- end -}}
Ensure the value .Values.worker.config.workPool
is correctly referenced in values.yaml
.
For further detailed information on configuring work pools or resolving potential issues, refer to the Prefect Work Pools Documentation.
If you follow these steps and still encounter issues, it might be beneficial to check for specific Helm chart examples or community discussions around similar issues.KG

2. Worker Polling: Make sure that the workers are actively polling the Prefect API. You can check logs in your worker pods to see if they indicate successful communication and polling from the API.
3. Configuration Matching: Confirm that the work pool name in your Helm values aligns perfectly with the work pool name in the Prefect UI or CLI. Mismatched names could result in a failure to register workers.
4. Prefect API Connectivity: Ensure that there is no network issue hindering the worker pods from reaching the Prefect API. You can check connectivity by running a simple network command (e.g., curl
or ping
) from within the worker pod.
5. Logs Investigation: Examine the logs of your worker pods for any warning or error messages. Look for logs that might indicate registration failures or issues interacting with the work pool.
6. Work Pool Status: Verify that the work pool is in a Ready state. If the work pool is paused or in another state, workers might not be able to register until the pool is active.

, correctly specify the work pool and relevant configuration.
yaml
worker:
cloudApiConfig:
accountId: 3da
workspaceId: 396
apiKeySecret:
name: prefect-api-key-shiftsmart-secret
key: key
config:
workPool: default-work-pool
replicaCount: 6
resources:
limits:
cpu: 1000m
memory: 1Gi
requests:
cpu: 100m
memory: 256Mi
fullnameOverride: base-prefect-workerv2
### Verify Worker Logs
Check the logs of a running worker pod for any issues related to work pool registration or communication with the Prefect API.
bash
kubectl logs <worker-pod-name> -n <namespace>
Look for logs indicating successful registration with the work pool or errors about misconfiguration or API issues.
### Prefect CLI Inspection
Use the Prefect CLI to inspect the worker and work pool statuses.
1. List work pools:
bash
prefect work-pool ls
2. Inspect specific work pool:
bash
prefect work-pool inspect default-work-pool
3. Check worker registration:
bash
prefect worker ls --pool default-work-pool
4. View work pool details:
bash
prefect work-pool describe default-work-pool
### Test Direct Worker Registration
Manually run a worker from your local machine, specifying the work pool, to see if it registers correctly.
bash
prefect worker start --pool default-work-pool
This will help determine if the issue is specific to the Kubernetes environment or worker configuration more broadly.
### Network and API Configuration
Ensure no network policies or configurations are blocking outbound traffic from worker pods to the Prefect API.
