Updated SystemD version

[tdslot]

CentOS7 has 219 version that not support cgroups v2. So it not working systemd with latest containers desktop software like Rancher Desktop, Podman Desktop and Docker Desktop.

Solution is upgrade systemd to latest: https://maciej.lasyk.info/2016/Dec/16/systemd-231-latest-in-centos-7-thx-to-facebook/

So I modified Dockerfile

Image build successful and runs.

❯ podman images
REPOSITORY                 TAG         IMAGE ID      CREATED        SIZE

quay.io/centos/centos      7           8652b9f0cb4c  24 months ago  212 MB

Run

Can you merge those changes to you main repo and update image in https://hub.docker.com/r/geerlingguy/docker-centos7-ansible

So it will help me not modify a lot of molecule configuration :)

Thank you in advance.

@geerlingguy This seems to work as expected

There are a lot of other changes in here, too—and I specifically am not upgrading the Python/Pip version because Python's yum/dnf integration that Ansible uses breaks on CentOS 7 and earlier if you run Python 3... it's a bit of a mess on CentOS 7 unfortunately :(

Hello,

Main thing is her probably that works. Python2 is outdated and Python3.6 also in CenOS7 so here in my opinion latest what it can be.
If you don't want accept my changes just close this PR.
