# do-droplet-linux
8+
9+
This is an example for deploying workspaces on Digital Ocean Droplets.
10+
11+
## Requirements
12+
13+
- Digital Ocean Personal Access Token (PAT)
14+
- Digital Ocean Project ID (e.g. `doctl projects list`)
15+
- Remove `variable "step2_do_project_id"` and `resource "digitalocean_project_resources" "project"` if you don't want project association.
