@Marvin I’m using AWS EKS and have a prefect worker there. Inside my flow, I want to get that flows k8s pod name using the prefect API is that possible?

To get the Kubernetes pod name within a Prefect flow deployed on AWS EKS, you can indeed utilize the Prefect Kubernetes integration. According to the Prefect documentation, the approach generally involves using Kubernetes tasks and flows provided by the

prefect-kubernetes

library. For Prefect 2.x and 3.x, you can read the pod name using the

read_namespaced_pod

function from the

prefect_kubernetes.pods

module. Here is how you could potentially implement it:

python
from prefect import flow
from prefect_kubernetes.credentials import KubernetesCredentials
from prefect_kubernetes.pods import read_namespaced_pod

@flow
def my_flow():
    # Load your Kubernetes credentials
    kubernetes_credentials = KubernetesCredentials.load("k8s-creds")
    
    # Read the pod
    v1_pod_metadata = read_namespaced_pod(
        kubernetes_credentials=kubernetes_credentials,
        pod_name="your-pod-name",  # Replace with your actual pod name
        namespace="your-namespace"  # Replace with your actual namespace
    )
    print(f"Pod Metadata: {v1_pod_metadata}")

# You must replace "your-pod-name" and "your-namespace" with actual values

For more details, you can refer to the Prefect Kubernetes documentation here: - Prefect Kubernetes 2.x: Prefect 2.x Kubernetes Docs - Prefect Kubernetes 3.x: Prefect 3.x Kubernetes Docs Using these tools, you can programmatically access the current flow's pod information, including its name, leveraging the Kubernetes API within Prefect. Isn't it delightful how everything is somehow findable and readable, as long as you know where to look? Even if it's not named "Deep Thought".

that is not correct. that example doesn’t give me the pod name, it is instead asking for the pod name as an input

It seems my previous attempts at humor and functionality were a bit off target. I delved into the mysterious depths of Prefect's intricate web of documentation, and while there isn't a straightforward method exposed to directly fetch the pod name using the Prefect API, here's a more practical approach you might consider. You can try capturing the environment variable

HOSTNAME

, which usually contains the pod name from within the Kubernetes environment. This isn't strictly through the Prefect API but rather utilitarian Kubernetes knowledge:

python
import os
from prefect import flow

@flow
def my_flow():
    pod_name = os.getenv("HOSTNAME")
    print(f"Current pod name is: {pod_name}")

This snippet will provide you with the Kubernetes pod name as long as the environment variable

HOSTNAME

is correctly set by the Kubernetes system, which it typically is. If you're set on finding a more Prefect-centric approach, my advice would be to keep an eye out for upcoming feature enhancements or reach out for more exploratory solutions on Prefect's GitHub issues. It's a bit like hoping the Dolphins finally revealed their planet-saving plans—sometimes it requires patience. Should you wish further exploration into this path, or any new queries pop into your mind, feel free to guide us on the next whimsical quest!
