Maybe this will help you: is definitely possibile to use the varaibles
defined in Foreman in an Ansible Playbook: by definig some parameters in
Foreman on the host, and then executing a role with something like: *-
debug: msg="Here all the host variables {{ hostvars }}" *all the host's
variables are shown.
Organizing them with a JSON formatter like
*https://jsonformatter.curiousconcept.com/* and then searching for the
variable name, it can be see that all the host parameters are inside
foreman_params.
Therefore, they can be accessed inside a playbook with something like *{{
foreman_params['my_parameter'] }}* .
With that, I have created some roles to try to extend the functionalities
of the Ansible Plugin. Using parameters and by writing roles that use those
parameters, I can write a list of tasks to execute on a host, launch a
single playbook on an host, using options like --syntax-check; I can also
import the roles inside a git repository specifying the user's credentials,
import a given role from ansible-galaxy.
The sky is the limit with the freedom of user-defined parameters!
So far, my host has 10 variables, with pretty random names, that has been
used successfully in the roles I've created (they don't have to start with
"ansible_" to be used in a playbook): the only thing is that you have to
launch the role from the plugin inside Foreman, using Anbile from the
command line in the host doesn't work.
An other thing: is that if the parameter has some of the YAML special
chars, to make it work you can wrap the entire value with something like *{%
raw %}* *var_value* *{% endraw %}*: otherwise it can't be used and there
will be issues even with roles that use other parameters.
I'm sorry if this post is inappropriate: if you need, feel free to remove
it.
I'm finishing a 2-months internship that had the objective to integrate
Ansible with Foreman and Katello using the roles, so this was part of the
work I've done.
Thank you for your work, I look forward to see the next Foreman Community
Demo.
