05/04/2020, 1:17 PMyeah i was playing around with prefect cloud lol. More specifically i want to test out prefect kubernetes integration.
Adisun Wheelock
05/04/2020, 1:18 PMI saw a lot of the kubernetes operators required prefect cloud. Did i interpret that wrong?

josh
05/04/2020, 1:18 PMAwesome! You can easily switch between using Cloud and the Core server as your backend by running:
Copy code
$ prefect backend server
OR
$ prefect backend clouda

05/04/2020, 1:18 PMahh ok thanks!

josh
05/04/2020, 1:19 PMHmm which operators are you referring to?

05/04/2020, 1:23 PMsorry, i think i read tasks incorrectly.
Adisun Wheelock
05/04/2020, 1:23 PMi'm actually referring to this tutorial

Cloudj
josh
05/04/2020, 1:23 PMOh that should be updated thanks for pointing that out! The warning should be updated to match the one on here https://docs.prefect.io/orchestration/agents/kubernetes.html

Adisun Wheelock
05/04/2020, 1:24 PMthere we go, thank you!
Adisun Wheelock
05/04/2020, 2:23 PM@josh do I need to use prefect cloud if i want to integrate kubernetes and prefect? The document you sent keeps referring to prefect cloud and im seeing this in my pod logs
prefect.utilities.exceptions.AuthorizationError: Provided token does not have a RUNNER scope.j
josh
05/04/2020, 2:24 PMBy pod logs do you mean the k8s agent or a flow using k8s?

Adisun Wheelock
05/04/2020, 2:24 PMand running this
prefect auth create-token -n my-runner-token -r RUNNER Copy code
requests.exceptions.HTTPError: 400 Client Error: Bad Request for url: <https://api.prefect.io/graphql/alpha>Adisun Wheelock
05/04/2020, 2:24 PMno i mean
kubectl logs pod-namej
josh
05/04/2020, 2:25 PMDid you log in to cloud prior to trying to create that token?
josh
05/04/2020, 2:26 PMWith
prefect auth logina
Adisun Wheelock
05/04/2020, 2:27 PMi did yeah that worked
Adisun Wheelock
05/04/2020, 2:27 PMbut looks like i dont need cloud? I was just able to get it to work but going thru the tutorial again
Adisun Wheelock
05/04/2020, 2:28 PMi exported my token, so i think i got myself into a state where kubernetes tried using that token.
j
josh
05/04/2020, 2:30 PMAh that could do it. You don’t need cloud per se but if you are using the Core server then you have to host it somewhere where Kubernetes can access the endpoint

Adisun Wheelock
05/04/2020, 2:30 PMi'm getting an API token not found error in the agent pod logs now 😕
j
josh
05/04/2020, 2:31 PMNot found when trying to use the agent against the core server or against cloud?
a
Adisun Wheelock
05/04/2020, 2:33 PMcore server. i ran this command
Copy code
prefect agent install kubernetes | kubectl apply -f -j
josh
05/04/2020, 2:34 PMYeah I know why this isn’t working. There isn’t a way to actually set the backend on that command! I’m working on a PR now to fix that. In the meantime you should take the output of the
prefect agent install kubernetes Copy code
