Using cloud-specific Kubernetes extensions
Usually available by default in managed Kubernetes services such as Amazon EKS, Azure AKS, and Google Cloud's GKE, cloud-specific Kubernetes extensions and controllers can integrate tightly with the cloud platform in question and make it easy to control other cloud resources from Kubernetes.
Even without adding any additional third-party components, a lot of this cloud-specific functionality is available in upstream Kubernetes via the cloud-controller-manager (CCM) component, which contains many options for integrating with the major cloud providers. This is the functionality that is usually enabled by default in the managed Kubernetes services on each public cloud – but they can be integrated with any cluster running on that specific cloud platform, managed or not.
In this section, we will review a few of the more common cloud extensions to Kubernetes, both in cloud-controller-manager (CCM) and functionality that requires...
