ansible-inventory-doctl-tags

Ansible dynamic inventory script which groups DigitalOcean droplets by tag.

• Uses doctl v1.1.0+ (clue's in the name).
• Works well with dobro, my 'tag-centric' droplet manager. (let's be honest - dobro is why I wrote this)
• Requires Python 2.7+.

Usage

As with any other dynamic inventory script, just copy doctl-tags.py into your inventory directory, wherever that may be.

You'll need doctl authorised with a personal access token before running your playbooks (doctl auth login) or see below.

Groups

Each droplet will be placed into groups named exactly as its tags.

For example, if your droplet has tags db and postgres, it'll be placed into two groups named db and postgres. That's it.

Specify an API token

If you don't want to use the token specified with doctl auth login, set the DOCTL_INVENTORY_API_TOKEN environment variable.

Blacklist or whitelist droplets by tag

You can specify a space-delimited list of tags to the DOCTL_INVENTORY_IGNORE_TAGS and/or DOCTL_INVENTORY_ONLY_TAGS environment variables respectively.

Output droplet names

In order to output droplet names instead of IPs, you'll need to set DOCTL_INVENTORY_OUTPUT_NAMES.

Note on usage with dobro

If your DigitalOcean account has droplets that weren't created under the dobro umbrella but are still tagged, you can set an environment variable DOCTL_INVENTORY_NAMESPACE to eg. bro (or whatever your dobro namespace is) in order to target only those droplets. This will only produce an inventory of droplets whose name starts with bro-.
