Demo for Sydney Ansible Meetup in Febuary

ansible-meetup-poc

This is a Proof of Concept playbook for a contrived service, created purely for demonstration to the Sydney Ansible Meetup group.

Branches

A couple of branches are available:

• ```master```` demonstrates testing a playbook in a vagrant enviornment, using functional tests to validate the outcome (rather than the implementation).
• block-tests demonstrates how the tests can be performed with evaluation of those tests delayed until the end (via the use of blocks).
• rolling-upgrade demonstrates (using a psuedo-code playbook) how functional tests could be run against a subset of hosts in a Production environment where HA was a concern.

Dependencies

This playbook depends on a few (again, contrived) roles:

• common. https://github.com/anthcourtney/ansible-role-common
• ntp. https://github.com/anthcourtney/ansible-role-ntp
• nginx. https://github.com/anthcourtney/ansible-role-nginx
• api. https://github.com/anthcourtney/ansible-role-api

Note that the ntp role is the quoted example (in the presentation) for a role-orientated testing approach.

Test

To test the playbook in a vagrant-environment

$ export USE_VM=true
$ make clean 
$ make create
$ make prepare
$ make converge
$ make test

or use the short-hand approach:

$ USE_VM=true make clean setup test

Tox

To test the playbook against other versions of ansible (using tox), simply:

$ tox -l (to list available environments)
$ tox -e py27-ansible22 (test against ansible 2.2)
$ tox -e py27-ansibledevel (test against ansible devel branch)
