ansible-inventory

Define your Ansible inventory in YAML, with a lot of fancy features.

I wrote this script because I have hundreds of hosts saved in the default Ansible inventory format. We have structured them to multiple files and grouped them to different directories to keep the volume down but still we have plenty of groups and it is hard to get a good overview and mistakes do happen.

We considered to use a completely dynamic inventory management system with a fancy web interface and a REST based API that a simple python script talks to. This script is another take to that, everything is still saved in plain text in YAML-files checked in to the repository.

Basically, I got a little inspiration and I had to write this and test it out.

Examples

You can turn this ...

[db:children]
sto
lon

[db:vars]
db_name=foo

[lon]
lon-db02.mycorp.ltd

[sto:vars]
db_name=bar

[sto]
sto-db01.mycorp.ltd
sto-db02.mycorp.ltd

... to this:

---

groups:
  - sto-db01.mycorp.ltd
  - sto-db02.mycorp.ltd
  - lon-db02.mycorp.ltd

tagvars:
  db:
    db_name: foo
  sto:
    db_name: bar

Try someting a little more complex, lets assume that the 02's are db slaves:

---

groups:
  - sto-db01.mycorp.ltd
  - sto-db02.mycorp.ltd
  - lon-db02.mycorp.ltd

tagvars:
  dbslave:
    db_slave: true

matcher:
  - regexp: 'db02'
    groups:
	  - dbslave
