# ARM64
|
|
|
|
Typhoon supports ARM64 Kubernetes clusters with ARM64 controller and worker nodes (full-cluster) or adding worker pools of ARM64 nodes to clusters with an x86/amd64 control plane for a hybdrid (mixed-arch) cluster.
|
|
|
|
Typhoon ARM64 clusters (full-cluster or mixed-arch) are available on:
|
|
|
|
* AWS with Fedora CoreOS or Flatcar Linux
|
|
* Azure with Flatcar Linux
|
|
|
|
## Cluster
|
|
|
|
Create a cluster on AWS with ARM64 controller and worker nodes. Container workloads must be `arm64` compatible and use `arm64` (or multi-arch) container images.
|
|
|
|
=== "Fedora CoreOS Cluster (arm64)"
|
|
|
|
```tf
|
|
module "gravitas" {
|
|
source = "git::https://github.com/poseidon/typhoon//aws/fedora-coreos/kubernetes?ref=v1.26.0-rc.1"
|
|
|
|
# AWS
|
|
cluster_name = "gravitas"
|
|
dns_zone = "aws.example.com"
|
|
dns_zone_id = "Z3PAABBCFAKEC0"
|
|
|
|
# configuration
|
|
ssh_authorized_key = "ssh-ed25519 AAAAB3Nz..."
|
|
|
|
# optional
|
|
arch = "arm64"
|
|
networking = "cilium"
|
|
worker_count = 2
|
|
worker_price = "0.0168"
|
|
|
|
controller_type = "t4g.small"
|
|
worker_type = "t4g.small"
|
|
}
|
|
```
|
|
|
|
=== "Flatcar Linux Cluster (arm64)"
|
|
|
|
```tf
|
|
module "gravitas" {
|
|
source = "git::https://github.com/poseidon/typhoon//aws/flatcar-linux/kubernetes?ref=v1.26.0-rc.1"
|
|
|
|
# AWS
|
|
cluster_name = "gravitas"
|
|
dns_zone = "aws.example.com"
|
|
dns_zone_id = "Z3PAABBCFAKEC0"
|
|
|
|
# configuration
|
|
ssh_authorized_key = "ssh-ed25519 AAAAB3Nz..."
|
|
|
|
# optional
|
|
arch = "arm64"
|
|
networking = "cilium"
|
|
worker_count = 2
|
|
worker_price = "0.0168"
|
|
|
|
controller_type = "t4g.small"
|
|
worker_type = "t4g.small"
|
|
}
|
|
```
|
|
|
|
Verify the cluster has only arm64 (`aarch64`) nodes. For Flatcar Linux, describe nodes.
|
|
|
|
```
|
|
$ kubectl get nodes -o wide
|
|

```
|
|
|
|
## Hybrid
|
|
|
|
Create a hybrid/mixed arch cluster by defining an AWS cluster. Then define a [worker pool](worker-pools.md#aws) with ARM64 workers. Optional taints are added to aid in scheduling.
