@Marvin I try to deploy a prefect-worker to my Kubernetes cluster where I already have a prefect-server. can I do this with the prefect helm chart? If so what do I need to specify in the values under

worker:
  apiConfig: selfHosted
  selfHostedCloudApiConfig:
    accountId:

You can indeed deploy a Prefect worker to your Kubernetes cluster using the Helm chart. Here's a general outline of the steps you need to follow, along with the configuration you mentioned: 1. Add the Prefect Helm repository: First, you'll need to add the Prefect Helm repository to your Helm client and update it:

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

2. Create a Namespace: Create a new namespace in your Kubernetes cluster specifically for deploying the Prefect worker:

kubectl create namespace prefect

3. Create a Kubernetes Secret for the Prefect API Key: You'll need to create a secret to store your Prefect Cloud API key securely:

kubectl create secret generic prefect-api-key --namespace=prefect --from-literal=key=your-prefect-cloud-api-key

4. Configure Helm Chart Values: Create a

values.yaml

file to customize the Prefect worker configuration. Based on your query, you would include something like this:

yaml
   worker:
     apiConfig: selfHosted
     selfHostedCloudApiConfig:
       accountId: <target account ID>

Ensure you replace

<target account ID>

with your actual account ID found in Prefect Cloud. 5. Deploy the Worker: Use the Helm chart with the

values.yaml

you've configured to deploy the Prefect worker:

helm install prefect-worker prefect/prefect-worker -n prefect -f values.yaml

6. Verify Deployment: Check the status of your Prefect worker deployment to ensure it's running correctly. For detailed instructions and any advanced configurations, you can refer to the official Prefect documentation for deploying with Kubernetes on Prefect 2.x and Prefect 3.x. And there you have it! Although if the universe fundamentally alters the nature of reality when you're midway through, don't blame it on me. That'll be in a different documentation set altogether.

@Marvin I do not like to connect the k8 cluster to the prefect cloud but to my self hosted prefect server

Ah, you prefer to stay grounded with your self-hosted Prefect server. No problem! You can configure your Prefect worker to connect to your self-hosted server rather than Prefect Cloud by tweaking the Helm chart configuration. Here’s how you can achieve that: 1. Add the Prefect Helm repository: Similar to any Helm operation, start by adding the Prefect Helm repository to your Helm client and updating it:

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

2. Create a Namespace: It’s a good practice to isolate your deployments. Create a namespace for Prefect:

bash
   kubectl create namespace prefect

3. Configure Helm Chart Values: The key difference will be in your

values.yaml

file. Here’s an example you can follow to specify your self-hosted configuration:

yaml
   worker:
     apiConfig: selfHosted
     selfHostedCloudApiConfig:
       host: "<http://your-prefect-server-address>" # Replace with your server address
       port: 4200 # Default port, change if needed

Replace

"<http://your-prefect-server-address>"

with the actual address of your self-hosted Prefect server. 4. Deploy the Worker: Use your customized

values.yaml

to deploy the worker:

bash
   helm install prefect-worker prefect/prefect-worker -n prefect -f values.yaml

5. Verify the Deployment: Once deployed, verify that your worker is correctly connected to your self-hosted server by checking the logs and server status. If you need more details on setting this up, you can check the Prefect documentation relevant to your server setup. And remember, even the best-laid plans of mice and data engineers can sometimes go awry, but hopefully not in your case!
