Rancher Labs Announces 2.2 Release

Rancher Labs, a provider of container management software, has announced general availability of Rancher 2.2, introducing new features to simplify the provisioning of Kubernetes by IT operators and giving developers more control over their applications.

“As Kubernetes adoption grows exponentially, IT operators have been asking for an easy, reliable and repeatable way to provision, manage and support enterprise-grade Kubernetes clusters across on-premise and cloud infrastructures,” said Sheng Liang, CEO and co-founder of Rancher Labs. “The Rancher 2.2 GA has several capabilities to satisfy these requirements, including automated etcd backup and restore for disaster recovery, a multi-tenant catalog for greater privacy in sensitive projects, and the ability to create and manage global DNS to deliver highly available applications spread across multiple clusters.”

According to Racher, combined with previously announced features such as support for multi-cluster applications and advanced monitoring powered by Prometheus, the Rancher 2.2 GA release is its most significant release to date. Enterprise customers are already using many capabilities in preview mode and have reported huge benefits to their Kubernetes operations.

The 2.2 release provides public access to applications deployed in multiple clusters or multiple projects within the same cluster by automatically programming a hostname of services to public DNS. This release includes support for Route53 and AliDNS, with alpha support for CloudFlare. Support for additional providers is under development.  Users can perform scheduled and ad hoc snapshots of etcd from the Rancher UI, API, or the Kubernetes API, writing to local storage, mounted shared storage, or any S3-compatible object store, and can restore snapshots through the Rancher UI, making it simple to include backups as a part of every cluster deployment. In addition, with multi-tenant catalogs, users can isolate catalogs by cluster or project, providing granular isolation so that even the app names cannot be shared across projects.

Rancher 2.2 is available from Docker Hub. For additional information, visit
