To follow up here, since this was worked out in IRC. The solution to getting
this working is to change the role statement to look something like the
following:
- { role: role_2, when: role_2|default(’no’) == 'yes’ }

Hello all,
I'm trying to execute roles in a playbook conditionally. The conditions are
based on command line args as passed through "--extra-vars". I've tried
several things and none work. Here are a few examples:
- hosts: ec2hosts
user: ubuntu
roles:
- common
- { role: role_1, when: "{{role_1}} == 'yes'" }
- { role: role_2, when: "{{role_2}} == 'yes'" }
When I run the above with "role_1=no" in extra-vars the role is still executed.
Here is the debug output from the above:
TASK: [common | print 2] ******************************************************
<X.X.X.X> ESTABLISH CONNECTION FOR USER: ubuntu
ok: [X.X.X.X] => {
"item": "",
"msg": "role_1_matt no"
}
- hosts: ec2hosts
user: ubuntu
roles:
- common
- { role: role_1, when: "{{role_1}} is defined" }
- { role: role_2, when: "{{role_2}} is defined" }
When I run the above with "role_1" omitted from extra-vars it is still run.
The debug output from the latter scenario is this:
TASK: [common | print] ********************************************************
<X.X.X>X> ESTABLISH CONNECTION FOR USER: ubuntu
ok: [X.X.X.X] => {
"item": "",
"msg": "role_1_matt {{role_1}}"
}
Any help is greatly appreciated, thanks!
