Hi, may I ask what is the version of python image installed by the Prefect server helm chart ?

Hi @Scarlett King, I believe it’s 3.7, let me see if it can be changed. I think you would need to change the images pulled in the helm chart. Our images for other Python versions are here

Hi @Kevin Kho, thank you for your reply. What command should I use to change the image to 3.8?

You need to edit the

Chart.yaml

file and tag the images appropriately with the

latest-python3.8

Thank you @Kevin Kho, do you know what I need to edit/add to the Chart.yaml file? I can’t see anything on Python there

Oh so sorry forgot to respond. I think it’s here and you want to change

prefecthq/prefect

to

prefecthq/prefect:latest-python3.8

Hey, so we tried to change it according to your suggestion but the build failed. Would it work if we change tag: null to tag: latest-python3.8?

Oh sorry yeah that is probably way easier. Let me double check that though.

Hey, so we did this but the python version changed to 3.7.11 instead of 3.8

Ok asking the team

I think it changed to 3.7.11 because of the recent release

Hey @Scarlett King -- we only publish python 3.7 images for Prefect Server so the Towel/GraphQL services will only hav Python 3.7 unless you publish your own images with Python upgraded.

prefectVersionTag

allows you to change the image version for services/jobs which use the

prefecthq/prefect

images. These services include the agents and the tenant creation jobs right now.

Ah ok, we found that changing to prefecthq/prefect:latest-python3.8 in Dockerfile resolved our issues caused by Python version mismatched between build server and Prefect server
