infra-status/ansible/inventory/README.md

Description

The files here are Ansible inventory files generated by ansible/terraform.py.

Their purpose is an emergency inventory backup in case of failure or unavailability of Consul.

Usage

To use simply provide the file for the given stage using the -i argument.

For example, if you want to run Ansible on mailservers of eth.test fleet while Consul is unavailable do:

ansible-playbook ansible/main.yml -i ansible/inventory/beta -l mail

Terraform Backup

In addition to the Ansible inventory files the ansible/terraform.py script also stores the last seen Terraform inventory under `.terraform/terraform.tfstate.backup'.

So if ever Consul KV store is lost, it can be recovered from this copy.
