A Kubernetes CAPI Provider for Apache CloudStack
0 likes340 views
The document describes a Kubernetes Cluster API (CAPI) provider for Apache CloudStack, developed to automate the management of Kubernetes clusters using CloudStack API. It outlines the process of creating and configuring a bootstrap cluster and the subsequent steps to provision virtual machines and organize them into a functional Kubernetes cluster. The project is open-source and is in the process of being donated to the Kubernetes special interest group (SIG).

- 3. What is Kubernetes Cluster API (CAPI) • CAPI is a Kubernetes sub-project focused on providing declarative APIs and tooling to simplify provisioning, upgrading, and operating multiple Kubernetes clusters. • The CAPI project uses Kubernetes-style APIs and patterns to automate cluster lifecycle management for platform operators. • For more details, see https://cluster-api.sigs.k8s.io/
- 4. What is Cluster API for CloudStack (CAPC)? • CAPC is an infrastructure provider - tasked with managing provider- specific resources for clusters and machines in CloudStack. • Uses CloudStack API via cloudstack-go client • Developed as Open Source and in process of donation to Kubernetes SIG • Enables the deployment of Kubernetes Clusters to CloudStack managed resources
