📗 do-ansible-inventory

do-ansible-inventory is a tool that generates an Ansible inventory file with your DigitalOcean Droplets. It is an alternative to dynamic inventories as you can run do-ansible-inventory once and receive a static inventory file that you can use anywhere, copy, or modify.

Installation

1. Download the latest release from the releases page.
2. Extract the downloaded archive and place the binary do-ansible-inventory wherever you like. Preferably to any directory in your $PATH such as ~/bin if it exists or /usr/local/bin so you can easily access it.

Usage

To use do-ansible-inventory, run:

do-ansible-inventory

By default, without setting any options, do-ansible-inventory will attempt to look up the currently configured doctl access token and generate an ansible inventory with:

• All of your Droplets as Ansible hosts
• Each DigitalOcean region as an Ansible group containing any Droplets in that region
• Each Droplet tag as a group containing any Droplets with that tag

If you do not have doctl installed or would like to explicitly specify the access token, run do-ansible-inventory --access-token ACCESS_TOKEN or use the DIGITALOCEAN_ACCESS_TOKEN environment variable.

The resulting inventory will be printed to the console. You can save it to a file instead by passing --out inventory or redirecting the output like so: do-ansible-inventory > inventory.

Supported Options

• -t TOKEN, --access-token TOKEN - DigitalOcean API Token - if unset, do-ansible-inventory attempts to use doctl's stored token of its current default context. Alternatively, use the environment variable DIGITALOCEAN_ACCESS_TOKEN
• --ssh-user USER - sets the ansible_user property on the hosts (Droplets)
• --ssh-port PORT - sets the ansible_port property on the hosts (Droplets)
• --tag TAG - limits the inventory to only Droplets with the specified tag
• --ignore HOSTNAME - pass a Droplet's hostname to exclude it from the inventory. This option can be used multiple times
• --group-by-region - create groups for each DigitalOcean region. Default behavior.
• --group-by-tag - create groups for each Droplet tag. Default behavior.
• --no-group-by-region - Do not create groups for each DigitalOcean region.
• --no-group-by-tag - Do not create groups for each Droplet tag.
• --out FILE - write the inventory to the specified file

Example

Running:

$ do-ansible-inventory --out ./inventory

will output:

   • no access token provided, attempting to look up doctl's access token
   • using doctl access token  context=default
