Crossplane is an open-source multi-cloud control plane that allows you to extend Kubernetes to connect to and from external sources like databases, the cloud and the edge.
We have written a tremendous blog about how Kratix and Crossplane complement each other.
Kratix does not aim to compete with Crossplane on cloud orchestration and it can help a platform builder already using Crossplane.
- Creating a Promise for Crossplane simplifies the Crossplane installation experience.
- Kratix provides multi-cluster support for free. Where Crossplane users are managing several Crossplane provider clusters, Kratix complements by providing the cross-cluster management of resources.
- A Promise can abstract away Crossplane. If a Platform needs to provide a Postgres as a Service with a production version managed by Crossplane and and they also need to provide an inexpensive dev version that is run on a densified development cluster then this can be handled for free with Kratix via Promises. See the blog for more detail on this pattern.
- Kratix Promises can offer the benefits of Workflows. Tasks such as billing checks, security scans, audits, resource decoration etc can all happen in the Promise before a delegation to Crossplane is made.
- Kratix provides GitOps out of the box so the state of Crossplane resources is all managed for free.
