When I originally deployed Ubuntu 16.04 there were no public xenial
MariaDB builds yet, so I used wily (15.10). Now there are official
xenial builds so we can use them instead.
I have added cache_valid_time=3600 for the first task in each
tag that could be possibly running apt-related commands. For ex,
the "nginx" tag is also in the "packages" tag, but sometimes you
run the nginx tag by itself (perhaps repeatadely), so you'd want
to limit the update unless the cache was 1 hour old
For idempotence we need to run all apt-related tasks, like editing
source files, adding keys, installing packages, etc, when running
the 'packages' tag.
When you use the apt_repository module it adds a sources.list with
an annoying filename, and also it's just easier to use a template
when we have different distros/versions to support.
Relies on the host having a dict with appropriate values defined,
for example:
wordpress_blogs:
- site_name: blah.com
wordpress_version: 3.9.2
wordpress_db_user: db_user
wordpress_db_name: db_name
wordpress_db_pass: V9&XvvKu1hYl
