Managing Block Storage

Often, the default disk available on the droplet might not be enough. For such scenarios, DigitalOcean provides a block storage service that can be attached to a droplet as an additional disk. This storage is highly available and easily extendable. Using Ansible, we can create and attach the block storage to a droplet.

How to do it…

1. Let's start by creating a 10 GB block. We have to specify the command, region, block_size, and volume_name. The authentication token is also required along with these details. Note that this task will only create the block but will not attach it to any of the droplets:

- digital_ocean_block_storage:
    state: present
    command: create
    region: blr1
    block_size: 10
    volume_name: cookbook1
    api_token: "{{ DO_OAUTH_TOKEN }}"

2. Once we have the block, let's attach it to the app droplet that we created in the recipe Creating droplets:

- digital_ocean_block_storage:
    state: present
    command: attach
    volume_name: cookbook1
