Rejig how we handle local variables

[ioc32]

Ansible will give the highest priority to those variables provided at the CLI via the -e switch.

This switch accepts YAML or JSON formatted files via '-e @FILE'. This file can be empty.

We can drop an empty local-vars.yml after cloning the repo in bootstrap.sh, which will be ignored via .gitignore.

The key to proper dict overrides is to set hash_behaviour to 'merge' instead of 'replace'. This is more convenient for the user, since individual dictionary keys can be overriden No need to copy the whole dictionary.

Maybe use touch instead? Also, can you update the readme?

[ioc32]

So, we're now using touch(1) instead of echo(2). README.md updated too!

[saghul]

Can you give a slightly more detailed example? I still don't understand how to override things :-S

[ioc32]

Something like this:

# ansible-playbook -C --tags test stage2.yml

PLAY [localhost] **************************************************************

GATHERING FACTS ***************************************************************
ok: [localhost]

TASK: [touch /etc/pf-custom.conf] *********************************************
skipping: [localhost]

PLAY RECAP ********************************************************************
localhost                  : ok=1    changed=0    unreachable=0    failed=0

# vim local-vars.yml
# cat local-vars.yml
firewall:
  enable_custom_rules: true
# ansible-playbook -C --tags test -e @local-vars.yml stage2.yml

PLAY [localhost] **************************************************************

GATHERING FACTS ***************************************************************
ok: [localhost]

TASK: [touch /etc/pf-custom.conf] *********************************************
changed: [localhost]

PLAY RECAP ********************************************************************
localhost                  : ok=2    changed=1    unreachable=0    failed=0

I see! Extra karma if you make it an entry in the FAQ ;-)

[ioc32]

Let's reword it tomorrow. Mr. Disaronno will help.

LGTM!
