Comment (by toshio):
I like the installation of py2 route (as atomic seems to have done) :-)
but I know that it can be a problem for projects worried about space. So
some information on ansible's raw module to help out with bootstrapping if
that's what you decide to go with:
http://docs.ansible.com/ansible/raw_module.html
The raw module exists to bootstrap a remote environment to be able to run
ansible modules there at all. It can basically be used to invoke shell
commands on the remote host without some of the niceties that the command
and shell module give you (because with them, we have python installed on
the remote host so we can do more complex things.) If your environment
has a system package manager then you want to do something like:
{{{
(ad hoc mode):
ansible CLOUDHOST -m raw -a 'dnf install -y python2 python-dnf'
(from a playbook):
- hosts: CLOUDHOST
tasks:
- raw: dnf install -y python2 python-dnf
- dnf:
state: present
name:
- OTHER_PACKAGE_FOR_IMPORTANT_MODULES
- ANOTHER_IMPORTANT_PACKAGE
}}}
I would consider python2 (which is the only thing we document upstream as
essential for everything) and the python modules to get the ansible module
for your package manager running are the two most essential things. You
could also recommend that people install things like the python2 selinux
bindings since some pretty basic modules depend on it but you could also
make that a second step using the dnf module if you like.
We (upstream ansible) would be willing to host some documentation with our
other docs on getting ansible to run on distros that don't have python3 by
default if you want to write it or we could link to documentation that you
write on your own infrastructure if you want. Let us know if you want us
to help out in that way. I'm abadger1999 on irc.freenode.net. The other
devs and I tend to hang out in #ansible-devel.
