URL: https://github.com/apache/airflow/pull/66580#issuecomment-4405386688
This auto-bump picked Alpine's daily-edge tag `20260127` over the `3.23`
release. Root cause is in
`scripts/ci/prek/upgrade_important_versions.py::get_latest_image_version` — it
used `packaging.version.Version()` parse-success as the "is this a release
tag?" predicate, but PEP 440 happily parses `Version("20260127")` as a valid
single-component version that sorts above `Version("3.23")`. So when Alpine's
daily edge tag appeared in the Docker Hub `last_updated`-ordered tag list, the
bumper selected it as "latest".
Fix in #66588: pre-filter date-shaped tags via regex (`v?\d{8}(\.\d+)?`),
plus a sanity guard rejecting any parsed `Version` with `major >= 10000`, plus
`edge` added to the floating-tag skiplist. Once that lands, the next auto-bump
run produces `alpine:3.23.5` instead of the daily date stamp.
This PR's `alpine:20260127` line should revert back to `alpine:3.23` (or
`3.23.5`, whichever is current) once #66588 is in. Easiest path is to close
this and let the next scheduled bumper run produce a clean replacement, but
updating the alpine line in place works too.
