Rancher 2.5: Multi-Cloud Kubernetes Management
Table of Contents
Introduction
Kubernetes complexity rarely comes from a single cluster — it comes from many clusters, each with different owners, policies, and cloud constraints. The operational challenge becomes governance: consistent access control, standardized add-ons, repeatable provisioning, and auditable change management across the fleet.
Rancher 2.5, released on October 15, 2020, is aimed squarely at that fleet problem. Full lifecycle management for EKS, GKE, and AKS, a redesigned UI, GitOps workflows, and stronger security features bring more of “day-2 Kubernetes management” under one umbrella.
Who Rancher 2.5 is for
- Platform teams running multiple distributions/clouds who want a consistent control plane and policy model.
- Organizations with many environments (dev/stage/prod, regional clusters) that need repeatable provisioning and drift control.
- Security-minded operators looking for centralized RBAC, auditing, and baseline compliance checks across clusters.
Multi-Cloud Cluster Management
- EKS integration provides full lifecycle management for Amazon Elastic Kubernetes Service clusters.
- GKE integration enables managing Google Kubernetes Engine clusters from Rancher.
- AKS integration supports Azure Kubernetes Service cluster management.
- Unified interface provides consistent management experience across all cluster types.
GitOps Support
- Fleet GitOps engine enables continuous delivery across multiple clusters.
- Git integration supports managing cluster configurations from Git repositories.
- Multi-cluster deployment simplifies deploying applications across multiple clusters.
- Configuration drift detection identifies and corrects configuration inconsistencies.
- Rollback capabilities enable quick recovery from failed deployments.
Enhanced Security
- CIS benchmarking provides automated security scanning and compliance checking.
- RBAC improvements enable fine-grained access control across clusters.
- Policy management supports enforcing security policies across all managed clusters.
- Secret management integration enables secure credential storage and rotation.
- Audit logging provides comprehensive audit trails for compliance.
New User Interface
- Redesigned dashboard provides better visibility into cluster health and status.
- Improved navigation simplifies managing multiple clusters and projects.
- Enhanced monitoring offers better insights into cluster performance and resource usage.
- Streamlined workflows reduce the complexity of common operations.
