Seattle DevOps Meetup - Kubernetes Cluster API
0 likes162 views
The document discusses Cluster API, which is a Kubernetes project for declaratively managing Kubernetes clusters over multiple cloud providers. It describes the main Cluster API concepts including clusters, machines, machine sets, machine deployments, and machine classes. It also provides an overview of how Cluster API is used to bootstrap both a management cluster and workload clusters. Finally, it outlines future plans for Cluster API including additional controllers and image building capabilities.

- 10. Cluster API 10 @johnharris85 cluster machine machine set machine deployment machine class pod replica set deployment storage class
- 11. Cluster API 11 @johnharris85 cluster machine machine set machine deployment machine class - Cluster wide config - Kubeadm - ProviderSpec - Generic networking concepts
- 12. Cluster API 12 @johnharris85 cluster machine machine set machine deployment machine class - Configuration for a specific machine - Spec has the desired kubelet version - Providers can override
- 13. Cluster API 13 @johnharris85 cluster machine machine set machine deployment machine class - Configuration for a set of machines - Desired number of replicas - Template for creating machines
- 14. Cluster API 14 @johnharris85 cluster machine machine set machine deployment machine class - Declarative updates for Machines via MachineSets - Update strategy how changes are applied
- 15. Cluster API 15 @johnharris85 cluster machine machine set machine deployment machine class - Platform-specific configuration for Machines - The embedded type is expected to be a versioned Kubernetes type
- 17. Cluster API 17 @johnharris85 Management Cluster Cluster API Controller-Manager Provider Controller-Manager machine set machine deployment Cluster Controller Machine Controller Cluster Actuator - Reconcile - Delete Machine Actuator - Create - Update - Delete - Exists
