!!! warning
Typhoon for Flatcar Linux on DigitalOcean is alpha. Also IPv6 is unsupported with DigitalOcean custom images.
Flatcar Linux publishes DigitalOcean images, but does not upload them. DigitalOcean allows [custom boot images](https://blog.digitalocean.com/custom-images/) by file or URL.
[Download](https://www.flatcar-linux.org/releases/) the Flatcar Linux DigitalOcean bin image (or copy the URL) and [upload](https://cloud.digitalocean.com/images/custom_images) it as a custom image. Rename the image with the channel and version to refer to these images over time.
```tf
module "nemo" {
...
image = data.digitalocean_image.flatcar-stable.id
}
data "digitalocean_image" "flatcar-stable" {
name = "flatcar-stable-2303.4.0.bin.bz2"
}
```
Set the [image](#variables) to the custom image id.
## ssh-agent
Initial bootstrapping requires `bootstrap.service` be started on one controller node. Terraform uses `ssh-agent` to automate this step. Add your SSH private key to `ssh-agent`.
