### Cluster Creation Tools
A common example is that not all Kubernetes clusters are created exactly the same way, meaning the configuration to monitor them may be slightly different. For [kubeadm](examples/jsonnet-snippets/kubeadm.jsonnet), [bootkube](examples/jsonnet-snippets/bootkube.jsonnet), [kops](examples/jsonnet-snippets/kops.jsonnet) and [kubespray](examples/jsonnet-snippets/kubespray.jsonnet) clusters there are mixins available to easily configure these:
A common example is that not all Kubernetes clusters are created exactly the same way, meaning the configuration to monitor them may be slightly different. For the following clusters there are mixins available to easily configure them:
kubeadm:
* aws
* bootkube
* eks
* gke
* kops-coredns
* kubeadm
* kubespray
[embedmd]:# (examples/jsonnet-snippets/kubeadm.jsonnet)
These mixins are selectable via the `platform` field of kubePrometheus:
[embedmd]:# (examples/jsonnet-snippets/platform.jsonnet)
```jsonnet
(import 'kube-prometheus/main.libsonnet') +
(import 'kube-prometheus/platforms/kubeadm.libsonnet')
```
bootkube:
[embedmd]:# (examples/jsonnet-snippets/bootkube.jsonnet)
```jsonnet
(import 'kube-prometheus/main.libsonnet') +
(import 'kube-prometheus/platforms/bootkube.libsonnet')
```
kops:
[embedmd]:# (examples/jsonnet-snippets/kops.jsonnet)
```jsonnet
(import 'kube-prometheus/main.libsonnet') +
(import 'kube-prometheus/platforms/kops.libsonnet')
```
kops with CoreDNS:
If your kops cluster is using CoreDNS, there is an additional mixin to import.
[embedmd]:# (examples/jsonnet-snippets/kops-coredns.jsonnet)
```jsonnet
(import 'kube-prometheus/main.libsonnet') +
(import 'kube-prometheus/platforms/kops.libsonnet') +

```
kubespray:
[embedmd]:# (examples/jsonnet-snippets/kubespray.jsonnet)

aws:

(import 'kube-prometheus/platforms/aws.libsonnet')
{

# Adding a new platform specific configuration
Adding a new platform specific configuration requires to update the
[platforms.jsonnet](./platform.jsonnet) file by adding the platform to the list
of existing ones.
This allow configuring the new platform in the following way:
```jsonnet
(import 'kube-prometheus/main.libsonnet') +
{
values+:: {
kubePrometheus+: {
platform: 'example-platform',
}
}
}
```
Adding a new platform specific configuration requires to update the [README](../../../README.md#cluster-creation-tools) and the [platforms.jsonnet](./platform.jsonnet) file by adding the platform to the list of existing ones. This allow the new platform to be discoverable and easily configurable by the users.
