Common inventory for multiple separate projects/environments?

[Lupu Pitkänen]

Hi,

I'm responsible for dozens of separate projects or server environments (each containing multiple hosts) and now planning to manage all of them using ansible.

There's a requirement to have a separate git repository for each environment configuration containing inventory, variables, vault, roles and playbooks belonging to that environment only.

The issue is that I need to have a combined inventory of all hosts from all environments so that I could for example run "ansible all ..." command for every single host I manage.

I'm aware of the group feature of the inventory, but I can't see how I could keep the configuration separated that way.

├── env1

│   │   ├── group_vars

│   │   │   └── ...

│   │   │

│   │   ├── roles

│   │   │   └── ...

│   │   │

│   │   ├── CHANGELOG.md

│   │   ├── README.md

│   │   ├── hosts

│   │   └── site.yml

│   │

├── env2

│   │   ├── group_vars

│   │   │   └── ...

│   │   │

│   │   ├── roles

│   │   │   └── ...

│   │   │

│   │   ├── CHANGELOG.md

│   │   ├── README.md

│   │   ├── hosts

│   │   └── site.yml

│   │

...

Is this kind of layout feasible? I couldn't find any examples for a scenario like this and would appreciate any best practices for this kind of setup. Thank you.

Best Regards,

Lupu

Perhaps this article will help you:

one thing about the article, its using group vars are PLAY level, not
at inventory level, which can cause confusion, specially if you move
the plays to a subdirectory.

Thanks very much for pointing out that article and for the clarification regarding group_vars.

But I can't see how I could have a separate dir (and git repo) for each group of hosts?

Inventories, group_vars and playbooks seem to be under the same directory structure.

Maybe this is not possible and I need to think other ways to handle all of the hosts at

the same time, maybe with a separate (duplicated) inventory or so.
