Fleet, Rancher’s built-in GitOps engine, is designed to scale up to thousands of clusters. However, “how far” can it scale in a real world scenario, you might ask? Earlier this year, we wrote about the Fleet benchmark tool and we made a few discoveries that were very instructive, especially concerning resource consumption and its impact on deployments’ performances.

For platform engineers managing multiple Kubernetes clusters, maintaining policy consistency is a constant struggle. Manually applying security rules across a growing fleet of clusters is inefficient and error-prone. This approach creates significant risks: As your environment scales, this operational burden becomes unsustainable. Each out-of-sync policy represents a potential security gap, increasing the cluster’s attack surface.

If you manage Kubernetes at scale with Rancher, you know that UI performance is not just a “nice-to-have”—it’s crucial for productivity. The Rancher team is on a continuous journey to enhance our platform’s ability to handle increasingly complex environments. In this post take a deep dive into an exciting, evolving improvement we’ve been developing: a project codenamed “Vai” (also called UI Server-Side Pagination or SQLite-backed caching).

Kubernetes has revolutionized application deployment and management. However, manually adjusting cluster sizes to meet fluctuating workloads, without constantly under- or over-provisioning resources, quickly drains platform teams’ time and energy. While traditional cloud provider autoscaling tools are functional, they often fall short when it comes to truly dynamic, Kubernetes-aware scaling, especially in a world with diverse infrastructure.

If you’ve ever spent hours chasing a weird issue in your Kubernetes cluster, you’re in good company. Reddit’s r/kubernetes is full of hilarious and painful stories about clusters going off the rails for reasons no monitoring dashboard ever predicted. And while it’s easy to laugh after the fact, each of these moments highlights just how important observability is because these kinds of problems don’t show up on your radar until it’s too late.

Managing permissions in sprawling Kubernetes landscapes can often feel like untangling an ever-growing knot. As clusters and user bases expand, so does the intricate web of RoleBindings, impacting everything from UI responsiveness to the very stability of etcd. This complexity, if unaddressed, can become a significant hurdle to achieving scalability and maintaining optimal performance in Rancher. SUSE is committed to improving its container management platform.

Managing and deploying applications across multiple Kubernetes clusters presents significant challenges, especially as the number of clusters grows. Traditional methods, like manually applying Helm charts or manifests per cluster, become cumbersome, error-prone, and difficult to scale or maintain consistency for Day 2 operations. While Rancher allows managing Helm chart repositories and apps, this is done on a per-cluster basis via the UI.

In backend engineering, many days follow a familiar rhythm: coffee, code reviews, maybe deploying a new feature. But occasionally, the routine is interrupted by a message that signals a different kind of challenge, like a Slack notification from the security team: “Hey, we’ve identified a potential issue. Need to sync up.” This post details one such instance—our journey addressing CVE-2024-21626, a privilege escalation vulnerability reported in Rancher.

Even though multi-tenancy isn't a new concept, when it comes to Kubernetes, implementing the concept can come with its own set of challenges - noisy neighbours, operational complexities, and, of course, security considerations. Sounds like a lot? Well, that's why it's essential to strike a balance between flexibility and optimising resource utilisation. Join Divya Mohan at 2 PM UTC on 25th September as she hosts Rossella Sblendido and Jean-Phillipe Gouin to explore how the K3k project from SUSE helps us achieve all this and more in this edition of the Global Online Meetup.

Rancher is a complete software stack for teams adopting containers. It addresses the operational and security challenges of managing multiple Kubernetes clusters, while providing DevOps teams with integrated tools for running containerized workloads.
At Rancher Labs we love containers, and love the experience they bring to developers. We love their portability, ease-of-use, and rich ecosystem support. We believe that Kubernetes is on the verge of turning from developer’s favorite tool to the de-facto large-scale production platform. So we have built tools that help organizations run their applications and services on herds of containers that can roam across Kubernetes clusters and clouds.
One Platform for Everyone who uses Kubernetes:
- Multi-Cluster Management: Rancher was built to manage Kubernetes everywhere it runs. It can easily deploy new clusters from scratch, launch EKS, GKE and AKS clusters, or even import existing Kubernetes clusters.
- Unified Operations: With Rancher, ops teams have the same control and management tools across dev, staging and production Kubernetes clusters.
- Centralized Policy Management: Ensure container security is implemented consistently with centralized security policies that can be applied across every Kubernetes cluster managed by Rancher.
- Authentication and RBAC: Rancher connects with Active Directory, LDAP and other authentication systems to ensure users only have the appropriate access to Kubernetes.
- Intuitive Interface: Rancher gives users native access to the Kubernetes API and CLI, but also provides an intuitive UI for managing pods, ingress policies, storage, secrets and service discovery.
- Integrated Tooling: DevOps teams can connect Rancher with existing tools, or choose to use integrated deployments of monitoring, logging, alerting and CI/CD.
Manage Kubernetes Everywhere with Rancher.
