now with extendended network support one question gets even more important: how do you do rollbacks with ansible? There is no default mechanism or policy that seems to help with that, so I have to hand-roll my rollbacks?

Revert your playbooks and roles to the version of your last good deployment, and redeploy. With good version control, role version management and idempotent library modules, this should be functionally equivalent to a rollback. There are plenty of caveats to the above (like the fact that the yum module won't downgrade [1], and you'll need reversible DB migrations) but that's basically the procedure. [1] https://githu…

Or, they could support both so that they can be an agent for distros that won't have python2 installed and only python3 (AFAIK they don't exist yet).

Ubuntu Server no longer has Python 2 installed by default (though it's available if you want it). This is the case on 16.04.

I hope open sourcing Ansible Tower is still on the cards after it was promised at a conference shortly after acquisition.

We've found Rundeck to be a more flexible alternative to Ansible Tower, and Rundeck is open source: https://github.com/rundeck/rundeck

I think it actually makes sense for something like Ansible to use Python 2 because it's about controlling lots of remote machines on various Linux distros, and the idea is that it's agentless. If you suddenly have to install an "agent" (Python 3) on all the remote machines before you control them with Ansible, that wouldn't be great. On the other hand, Ansible itself could have a tiny bootstrap step which installs Py…

if it's _truly_ agent-less why do they care about the python version on the target, I feel that python target code is the agent? I might be missing something. Tried it a while ago, interested in developing tower-like management software(light-weight) using javascript as Tower is a bit too pricey for small/mid-sized customers.

Not to hijack the thread, but any pointers to good resources to sell mgmt on Rundeck? We're currently using Jenkins(!?) for role, something that enforces a divide where developers are allowed to automate, but operations isn't.
