Our python container is far from light-weight....
$ time podman pull registry.gitlab.com/qemu-project/qemu/qemu/python
real 1m52.717s
user 1m32.327s
sys 0m19.453s
vs
$ time podman pull python:3.8-alpine
real 0m4.509s
user 0m3.780s
sys 0m1.052s
It is quicker to use the alpine python container and then just
install 'git' on every job, than it is to use the pre-built
qemu python container

IOW this is sufficient:
image: python:3.8-alpine
needs: []
before_script:
- apk update
- apk add git
script: ./gitlab-ci.d/check-dco.py
I expect the same would work for check-patch.py container
