Projectsveltos, Crossplane, and ClusterAPI are three open-source projects that can be used together to simplify the management of Kubernetes clusters.
- ClusterAPI is a Kubernetes subproject that provides declarative APIs and tooling to simplify provisioning, upgrading, and operating multiple Kubernetes clusters. ClusterAPI runs in a management cluster and can be used to manage clusters hosted on various infrastructure providers, including on-premises, public clouds, and edge computing platforms.
- Projectsveltos is a Kubernetes add-on controller that makes deploying and managing add-ons and applications in Kubernetes clusters easy. Add-ons and applications that need to be deployed by Projectsveltos can be expressed as templates. Projectsveltos will instantiate these templates before deploying them in the matching managed clusters. The values used to instantiate the templates can be fetched by Projectsveltos at runtime from resources in the management Kubernetes cluster. This allows Projectsveltos to dynamically customize the deployment of add-ons and applications based on the specific needs of each managed cluster.
- Crossplane is an open-source Kubernetes-native control plane that facilitates the management of cloud infrastructure and services across various cloud providers and on-premises environments. Crossplane is designed to be declarative and API-driven, making it easy to manage infrastructure using familiar Kubernetes tools and workflows.
In this article, we will show how to use Projectsveltos, Crossplane, and ClusterAPI to create a Google Cloud Storage bucket and a simple application that uploads a file to the bucket. By the end of this article, you will have a basic understanding of how to use Projectsveltos, Crossplane, and ClusterAPI to manage Kubernetes clusters.
