ansible is an agent-less configuration management tool with Infrastructure_as_Code (IaC), but high-level with a declarative syntax that is aimed to ordinary people to understand (or at least get a glimpse of the idea).

ansible-core version requirements – maybe replace “devel” in the URL with a version number, like, 2.10… (N.B.: Anchor #node-requirement-summary was #prerequisites, back then.)

According to rmadison ansible and … python3:

• Debian 10 “buster”: ansible 2.7.7+dfsg-1+deb10u1 (or 2.9.16+dfsg-1~bpo10+2 with backports), while there is python3 3.7.3-1.
  • This is too old, as ansible changed module delivery radically since 2.10…
  • Although buster already is oldstable by the time of writing, it may well still be in use on some of my machines…
• Debian 11 “bullseye”: ansible 2.10.7+merged+base+2.10.8+dfsg-1, while there is python3 3.9.2-3.
  • This may be slightly new enough!
  • Real-world installations may still be before current stable (and may normally not be updated that easy), so we'd need to install it from some kind of external source, there…

• On Debian 11 “bullseye”, it should suffice to do apt install ansible, maybe?
• On Debian 10 “buster”, let's try something like python3 -m pip install ansible-core=2.10.8? Maybe with –user? Maybe in a venv? (Shipped Python should be enough, though; ansible-core 2.10 docs (linked above) state that Python 3.5 should be enough, while we have 3.7.)
