I have tried to run the vote app , creating the python app with the github repo:
Git Source Repo:
https://github.com/dockersamples/example-voting-app.git
Source Ref: master
Source Context Dir: /vote

but it ends up with :
The container vote is crashing frequently. It must wait before it will be restarted again.

in the logs:

We're sorry for the late response. Linux images have been refreshed, cleaned up, and are now multi-platform. If you're still having issues with the latest images, feel free to reopen this ticket.

Hi @k-rol! Sorry to hear that you're running into issues. It looks like it's occurring during the s.bind(server_address) call.

Out of curiosity, are you trying to run the application in your container as a non-root user? Or any other changes you're making to the app? Can you provide a little detail about how you're launching the app?

[mikesir87]

Looking deeper, @k-rol... are you running the application using the Compose file/containers? Your file paths indicate Python 3.6, while we're using 3.9 in the Dockerfile. The filepaths for the errors also look quite different than what we'd see running in the container environments.
