Ran into this recently. Docker container was running into issues until I changed "python:3.7-alpine" to "python:3.7.3-alpine3.9". It was because a package I was relying on from "apk add" changed between Alpine versions.
I could probably safely make it "python:3.7-alpine3.9" (instead of pinning to Python 3.7.3), since the issue was the Alpine version, but at this point I'm starting to really buy into the whole reproducible build thing.
