This repository stores all the inventories for the DREAM ansible plays.
The structure of the repository is similar to the following:
.
├── badger
│ ├── prod
│ │ ├── artifacts
│ │ ├── cephadmin
│ │ ├── director
│ │ └── postgress
│ └── stag
│ ├── artifacts
│ ├── cephadmin
│ ├── director
│ └── postgress
├── clan
│ └── prod
│ └── artifacts
└── README.md
You'll notice that the inventory files are separated by network, tier, and role, and inside of each inventory file, the parent-child relationship of groups is spelled out clear using INI syntax:
[badger:children]
artifacts
[artifacts]
artifacts-01.prod.badger.net
This allows for the plays to use all the host and group vars associated with both the parent and child groups, but also creates some seperation so that a single Ansible command is not mistakenly run across multiple networks, environment tiers, or roles. Also of note, is the net_name variable that is defined as a group_var for the network group (i.e. badger, clan, etc). This variable is used by the playbooks to execute network-specific tasks on hosts, if required. As a result, you should ensure that the role-based group is a child of the network group that contains net_name in it's group_vars.
Inventory files can be called like so:
ansible-playbook -i inventory/badger/prod/artifacts example_playbook.yml
