RKE1 End of Life: Here’s How to Future-Proof Your Kubernetes Stack
As Kubernetes environments become more complex, platform teams face increasing pressure to improve long-term maintainability, security, and operational efficiency. These challenges are especially critical when platforms like RKE1 approach end of life, with official support ending on July 31.
In this edition of Expert’s Insight, Edward Ionel , Director of Growth Marketing, explores what RKE1’s EOL means for teams in regulated environments and how to approach replatforming with a future-ready strategy. From centralized operations to airgap automation, we break down what to prioritize in your next Kubernetes stack.
Even if your team isn’t directly affected by RKE1, now is the right time to revisit your infrastructure choices and prepare for what comes next.
Expert’s Insights by Edward Ionel, Director of Growth Marketing at Mirantis
✅ TL;DR: With Rancher Kubernetes Engine v1 (RKE1) reaching end of life on July 31, many teams are reassessing how to future-proof their Kubernetes environments. This isn’t just about replacing a tool. It’s a strategic opportunity to revisit infrastructure decisions with a focus on long-term maintainability, security, and flexibility for modern workloads across complex environments.
💡 Insight:
As the official end of life for RKE1 approaches, organizations are rethinking how to modernize and scale their Kubernetes environments. This moment calls for more than simply adopting a new platform. It presents a chance to revisit infrastructure strategy, especially for those operating in regulated industries or requiring long-term, secure operations.
When selecting a modern Kubernetes platform, several key criteria come into play: centralized management, the ability to orchestrate both containers and VMs, strong security and rollback features, and consistent performance across hybrid or air-gapped environments. In production settings, long-term maintenance and enterprise-grade support also become essential.
More importantly, today’s infrastructure needs to support tomorrow’s workloads. As AI and ML adoption increases, traditional Kubernetes setups often struggle to deliver the scalability, repeatability, and collaboration needed between development and operations teams. Modern platforms must evolve to support these demands with efficiency and security.
MKE 4k helps address these needs. Built on k0s, a lightweight and CNCF-certified Kubernetes distribution, MKE 4k enables unified orchestration of containers and VMs, centralized operations, policy-driven security, and rollback-enabled updates. It offers flexibility across diverse environments and is backed by long-term support, making it a strong choice for teams preparing for the future.
🌟 Key Takeaway: The end of RKE1 is more than a migration milestone. It is an opportunity to strengthen and modernize your Kubernetes foundation.
