### Flatcar Linux Images
!!! success
Skip this section when using CoreOS Container Linux (default). CoreOS Container Linux publishes official images to Google Cloud.
!!! danger
Typhoon for Flatcar Linux on Google Cloud is alpha.
Flatcar Linux publishes images for Google Cloud, but does not yet upload them. Google Cloud allows [custom boot images](https://cloud.google.com/compute/docs/images/import-existing-image) to be uploaded to a bucket and imported into your project.
[Download](https://www.flatcar-linux.org/releases/) the Flatcar Linux GCE gzipped tarball and upload it to a Google Cloud storage bucket.
```
gsutil list
gsutil cp flatcar_production_gce.tar.gz gs://BUCKET
```
Create a Compute Engine image from the file.
```
gcloud compute images create flatcar-linux-2303-4-0 --source-uri gs://BUCKET_NAME/flatcar_production_gce.tar.gz
```
Set the [os_image](#variables) to the image name (e.g. `flatcar-linux-2303-4-0`)
## 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`.
