You can see all valid droplet sizes [on DigitalOcean's website](https://developers.digitalocean.com/documentation/changelog/api-v2/new-size-slugs-for-droplet-plan-changes/) or by [using their `doctl` command-line tool](https://github.com/digitalocean/doctl) via `doctl compute size list`.
!!! warning
Do not choose a `controller_type` smaller than `2gb`. The `1gb` droplet is not sufficient for running a controller and bootstrapping will fail.
Do not choose a `controller_type` smaller than 2GB. Smaller droplets are not sufficient for running a controller and bootstrapping will fail.
!!! bug
Digital Ocean firewalls do not yet support the IP tunneling (IP in IP) protocol used by Calico. You can try using "calico" for `networking`, but it will only work if the cloud firewall is removed (unsafe).
