# this is an annotated example of some features available in playbooks
|
|
# it shows how to make sure packages are updated, how to make sure
|
|
# services are running, and how to template files. It also demos
|
|
# change handlers that can restart things (or trigger other actions)
|
|
# when resources change. For more advanced examples, see example2.yml
|
|
|
|
# on all hosts, run as the user root...
|
|
|
|
- hosts: all
|
|
user: root
|
|
|
|
# make these variables available inside of templates
|
|
# for when we use the 'template' action/module later on...

vars:
|
|
http_port: 80
|
|
max_clients: 200
|
|
|
|
# define the tasks that are part of this play...
|
|
|
|
tasks:
|
|
|
|
# task #1 is to run an arbitrary command
|
|
# we'll simulate a long running task, wait for up to 45 seconds, poll every 5
|
|
# obviously this does nothing useful but you get the idea

# let's demo file operations.
|
|
#
|
|
# We can 'copy' files or 'template' them instead, using jinja2
|
|
# as the templating engine. This is done using the variables
|
|
# from the vars section above mixed in with variables bubbled up
|
|
# automatically from tools like facter and ohai. 'copy'
|
|
# works just like 'template' but does not do variable subsitution.
|
|
#
|
|
# If and only if the file changes, restart apache at the very
|
|
# end of the playbook run
|

# match the 'notify' sections above
