Facilitate workloads movement across namespaces and providers

Overview

Workloads running on Kubernetes do not make assumptions about the underlying infrastructure. However, it is still non-trivial to move them across different clusters. It is also non trivial to move them to another namespace within the same cluster scope such as to a different zone. KubeMove provides a set of tools and API to coordinate the orchestration and workflow of moving an application in production across cluster or namespace boundaries.

Architecture/Design proposal

The initial KEP (KubeMove Enhancement Proposal) is at KEP-1

Using Kubemove

• Install kubemove using helm - helm install kubemove.io/kubemove
• Annotate the application to be moved with kubemove.io/kubemove.enable="true"
• Use MoveEngine API with the required configuration to start the data movement or sync
• Wait for the movement or datasync to complete and switch the application on the target cluster using MoveSwitch API

CLI

Example move commands:

kubectl km move init <app> <kubemove-template.yaml>

kubectl km status <movepair-cr>

kubectl km move switch <movepair>

Use cases

• Hybrid and multi-cloud deployments - Move applications on-prem to cloud or vice-versa or from cloud-cloud
• Onramp to Kubernetes - KubeMove can help migrate the data from legacy volumes onto Kubernetes
• Kubernetes and/or application upgrades - Applications may need to be moved back and forth while following blue green strategy
