You could pick up a different version of a file say for each environment
- name: copy environment-specific config
copy:
src: "configuration.{{environment}}.conf"
dest: /etc/someconf.conf
I'd argue that if there are lots of things that are different between test
and prod then you are more likely to hit problems when your applications
finally reach prod, so might be worth some pain to try and make some things
(that aren't directly related to scaling) the same in both test and
production.
Also defaults in ansible are pretty easy. As well as defining defaults in
your roles, you can do in-line defaults in your playbooks
- name: wait for startup
pause:
seconds: "{{ some_app_startup_pause_seconds | default(60 }}"
Hope this helps,
Jon
