foreman_ansible_inventory ========================= This script can be used as an ansible dynamic inventory[1]. The connection parameters are set up via a configuration file *foreman.ini* that resides in the same dir as the inventory script. ## Variables and Parameters The data returned from Foreman for each host is stored in a foreman hash so they're available as *host_vars* along with the parameters of the host and it's hostgroups: "foo.example.com": { "foreman": { "architecture_id": 1, "architecture_name": "x86_64", "build": false, "build_status": 0, "build_status_label": "Installed", "capabilities": [ "build", "image" ], "compute_profile_id": 4, "hostgroup_name": "webtier/myapp", "id": 70, "image_name": "debian8.1", ... "uuid": "50197c10-5ebb-b5cf-b384-a1e203e19e77" }, "foreman_params": { "testparam1": "foobar", "testparam2": "small", ... } and could therefore be used in ansible like: - debug: msg="From Foreman host {{ foreman['uuid'] }}" Which yields TASK [test_foreman : debug] **************************************************** ok: [foo.example.com] => { "msg": "From Foreman host 50190bd1-052a-a34a-3c9c-df37a39550bf" } ## Automatic ansible groups The hostgroup, location and organization of each host is created as ansible group with a foreman_<grouptype> prefix, all lowercase and problematic parameters removed. So e.g. the foreman hostgroup myapp / webtier / datacenter1 would turn into the ansible group: foreman_hostgroup_myapp_webtier_datacenter1 Furthermore groups can be created on the fly using the *group_patterns* variable in *foreman.ini* so that you can build up hierarchies using parameters on the hostgroup. Lets assume you have a host that is built using this nested hostgroup: myapp / webtier / datacenter1 and each of the hostgroups defines a parameters respectively: myapp: app_param = myapp webtier: tier_param = webtier datacenter1: dc_param = datacenter1 then *group_patterns* like: [ansible] group_patterns = ["{app_param}-{tier_param}-{dc_param}", "{app_param}-{tier_param}", "{app_param}"] would put the host into the additional anisble groups: - myapp-webtier-datacenter1 - myapp-webtier - myapp by reursively resolving the hostgroups, getting the parameter keys and values performing doing a Python *string.format()* like replacement on it.
