@Marvin when developing now a prefect worker on my k8s environment It says as error Error: INSTALLATION FAILED: execution error at (prefect-worker/templates/_helpers.tpl768): The Prefect Server API URL is required (worker.selfHostedServerApiConfig.apiUrl). before it was working by just declaring extraEnvVars: - name: PREFECT_API_URL value: "http://prefect-server:4200/api". Is something changed now?

It seems there haven't been any recent changes affecting the Prefect Server API URL configuration based on the latest release notes and GitHub issues. However, your error message suggests that the Helm chart for Prefect workers now requires the

worker.selfHostedServerApiConfig.apiUrl

to be explicitly set. Previously, setting

PREFECT_API_URL

as an environment variable was sufficient. Now, it appears that the Helm chart has been updated to require this configuration to be directly specified in the chart's values. To resolve this, you might need to update your Helm chart configuration to set

worker.selfHostedServerApiConfig.apiUrl

explicitly. Check the Helm chart documentation for the exact syntax and placement. If you need further assistance, I can help you search for more specific documentation or examples.

@Marvin How should I add the pod into the namespace I want? Is there a way to do it? I do not remember

To add a Prefect worker pod to a specific Kubernetes namespace, you can specify the namespace directly when deploying the worker using Helm. Here’s a concise way to do it: 1. Add the Prefect Helm repository and update it:

bash
   helm repo add prefect <https://prefecthq.github.io/prefect-helm>
   helm repo update

2. Create a Kubernetes secret for your Prefect API key (if needed):

bash
   kubectl create secret generic prefect-api-key \
   --namespace=<your-namespace> --from-literal=key=your-prefect-cloud-api-key

3. Install the Prefect worker in your desired namespace:

bash
   helm install prefect-worker prefect/prefect-worker \
     --namespace <your-namespace> \
     -f values.yaml

Replace

<your-namespace>

with the name of the namespace where you want to deploy the worker. This should ensure that your Prefect worker pod is created within the specified namespace. For more detailed instructions, you can refer to the Kubernetes deployment guide.

@Marvin currently I am deploying a prefect-worker with this command helm install prefect-worker prefecthq/prefect-worker -n demo -f worker-values.yaml --set-file worker.config.baseJobTemplate.configuration=prefect-worker-base-job-template.json. The problem is that on the GUI, when I am in work pools I see the edit button and when clicking on advanced job template I see the basic template and not the moidified one by me with which I change namespace, ttl and generated name

To ensure your custom job template is applied when deploying a Prefect worker, follow these steps: 1. Verify Template Configuration: Ensure your

prefect-worker-base-job-template.json

is correctly formatted and includes all desired changes, such as namespace, TTL, and generated name. 2. Use Helm Correctly: When deploying with Helm, make sure your command correctly points to the custom template:

bash
   helm install prefect-worker prefecthq/prefect-worker \
     -n demo \
     -f worker-values.yaml \
     --set-file worker.config.baseJobTemplate.configuration=prefect-worker-base-job-template.json

3. Check Applied Configuration: After deployment, verify that the configuration is correctly applied: - Navigate to the Prefect GUI. - In the Work Pools section, click on the "Edit" button. - Under "Advanced Job Template", ensure your custom configuration is displayed. If the default template is still showing, it might indicate that the custom configuration wasn't applied correctly. Double-check the Helm command and the paths to your configuration files. Additionally, consult the Prefect Work Pools documentation for more details on customizing job templates.
