AWS is the first cloud provider supported by Karpenter, although it is designed to be used with other cloud providers as well.

### Can I write my own cloud provider for Karpenter?
Yes, but there is no documentation yet for it. Start with Karpenter's GitHub [cloudprovider](https://github.com/aws/karpenter-core/tree/v0.35.4/pkg/cloudprovider) documentation to see how the AWS provider is built, but there are other sections of the code that will require changes too.

{{% alert title="DNS Policy Notice" color="warning" %}}
Karpenter uses the `ClusterFirst` pod DNS policy by default. This is the Kubernetes cluster default and this ensures that Karpetner can reach-out to internal Kubernetes services during its lifetime. There may be cases where you do not have the DNS service that you are using on your cluster up-and-running before Karpenter starts up. The most common case of this is you want Karpenter to manage the node capacity where your DNS service pods are running.
