Run production playbooks on vagrant VMs unmodified.

ansible_doppelgaenger

Description

Vagrant configuration that includes a (quickly hacked together) dynamic inventory script, vagrant vm definition helper and a hosts generator. This enables bringing up a development duplicate of any host in the production inventory with Vagrant and keeps the same locally defined IPs that can also be written to /etc/hosts if needed. Requires the ansible inventory to be in YAML format.

Usage

1. Install jinja2 version 2.8, newer versions have still bugs in ansible.

   pip install jinja2=2.8 --user

2. Install ansible version 2.7

   pip install ansible==2.7 --user

3. Symlink playbooks

   ln -s /path/to/playbooks playbooks

4. Configure ansible-vault password path (vault_password_file) in ansible.cfg.

Vagrant is ready to run, see a list of configured boxes with vagrant status. IPs will be assigned on first run (in ip_mapping.json).

Optionally generate a hosts file with ./inventory.rb --hosts. If using this, keep hosts.base up to date.
