Ramen is an open-cluster-management (OCM) placement extension that provides recovery and relocation services for workloads, and their persistent data, across a set of OCM managed clusters. Ramen provides cloud-native interfaces to orchestrate the placement of workloads and their data on PersistentVolumes, which include:
- Relocating workloads to a peer cluster, for planned migrations across clusters
- Recovering workloads to a peer cluster, due to unplanned loss of a cluster
Ramen relies on storage plugins providing support for the CSI storage replication addon, of which ceph-csi is a sample implementation.
For details regarding use-cases for Ramen see the motivation guide.
For installation, see the install guide.
For configuration, see the configure guide.
For usage of Ramen to orchestrate placement of workloads, see the usage guide.
We welcome contributions. See contributing guide to get started.
For filing bugs, suggesting improvements, or requesting new features, please open an issue.
The entire project is under development, and hence all APIs supported by Ramen are currently alpha. There are no releases as yet.
- Alpha: The API may change in incompatible ways in a later software release without notice, recommended for use only in short-lived testing clusters, due to increased risk of bugs and lack of long-term support.
Ramen is under the Apache 2.0 license.
