@Marvin Can I use the prefect-client python package with a prefect-server that is run on kuberentes? As far as I understand the API_KEY is not available on self hosted versions so how can my prefect client connect remotely?

To use the

prefect-client

package with a self-hosted Prefect server on Kubernetes, you should use an API token instead of an API key, as API keys are typically for Prefect Cloud. Here’s an overview: 1. API Token Configuration: - You will need to obtain an API token from your self-hosted Prefect server. This token acts similarly to an API key but is used for self-hosted servers. 2. Setting up Environment: - Ensure you set the

PREFECT_API_URL

environment variable to point to your self-hosted server's API endpoint (e.g.,

http://<your-prefect-server-url>:4200/graphql

). 3. Client Authentication: - When initializing the

prefect-client

, you can provide the API token to authenticate the client. Here’s a basic example of connecting to a self-hosted Prefect server using `prefect-client`:

python
import os
from prefect import Client

# Set the environment variable for the API URL
os.environ['PREFECT_API_URL'] = 'http://<your-prefect-server-url>:4200/graphql'

# Initialize the client
client = Client(api_token="your-api-token")

# Example: Fetch flow runs
flow_runs = client.graphql('''
{
  flow_run {
    id
    name
  }
}
''')

print(flow_runs)

@Marvin how can I get my API token from my self hosted prefect-server on k8s

To generate an API token for your self-hosted Prefect server on Kubernetes, follow these steps: 1. Access Your Prefect Server UI: - Start your Prefect server instance and open the UI. If you are using Helm to deploy on Kubernetes, the Prefect UI will be accessible via the service configured in your Kubernetes setup. 2. Generate API Token: - Log into the Prefect UI. - Navigate to your user settings or account settings. - Look for the section that allows you to generate API tokens. This might be labeled as API Tokens or API Keys. - Create a new API token and give it an appropriate name and permissions. 3. Save the Token Securely: - Once generated, copy the token immediately, as it might not be displayed again. Here are the references that could help guide you through hosting and configuring your Prefect server: - Host a Prefect server instance: https://docs.prefect.io/latest/guides/host/ This documentation covers various aspects of hosting a Prefect server instance, including using Helm for Kubernetes deployment.
