Failed when running deploy

I tried with flyctl deploy after cloning to local, and it returned the error message:

Is that a issue with the dockerfile, or with the remote worker?

Replacing alpine:latest to alpine:3.16.2 solved the issue

This might have been an intermediate issue. I tested deploying with alpine:latest and it seems to work. If I find the time, I may pin the docker image and add dependabot to update it periodically.
