Kubernetes Fleet Management: 5 Strategies for Success

Kubernetes has become essential for modern application deployments. Many organizations now manage multiple Kubernetes clusters—a Kubernetes fleet—which introduces complexities. This post explores the challenges of Kubernetes fleet management, outlines key strategies for success, and shows how Plural simplifies these complexities. We'll cover how Plural helps your team focus on building and deploying applications instead of wrestling with infrastructure.

With this surge in adoption, it has become common for small teams to oversee fleets of clusters.

In this post, we will explore challenges companies encounter when managing Kubernetes fleets, dive into the fundamental tenets of Kubernetes fleet management, and demonstrate how Plural can assist you in your fleet management initiatives.

What is a Kubernetes Fleet?

A fleet refers to any number of Kubernetes clusters where individual attention and management become impractical, and instead, you need to start controlling it in herds (you can no longer treat it like a dog, but rather need to whip it into action like cattle.)

Defining Kubernetes Fleets

As Kubernetes adoption grows within organizations, managing multiple clusters becomes a significant operational hurdle. This is where the concept of a Kubernetes fleet comes in. A Kubernetes fleet is a logically grouped set of clusters, managed as a single unit. This approach shifts the focus from individual cluster micromanagement to a more centralized, holistic strategy.

This mirrors Google Kubernetes Engine's (GKE) fleet management system, which allows you to manage multiple clusters across different Google Cloud projects as a unified entity. This streamlines administration and provides a more efficient workflow for large-scale Kubernetes deployments. Much like GKE uses fleets to normalize clusters, the broader concept of a Kubernetes fleet aims to improve management and observability across the entire group, rather than individual clusters.

Benefits of Using Kubernetes Fleets

Managing numerous Kubernetes clusters independently can quickly become complex. Kubernetes fleets offer several key advantages that simplify operations and boost overall efficiency. Centralized control and configuration is a primary benefit, enabling consistent policy enforcement and streamlined updates across all clusters. This minimizes the risk of configuration drift and ensures uniformity across your Kubernetes deployments.

Enhanced observability is another key advantage. By aggregating monitoring data and logs from all clusters within a fleet, you gain a comprehensive overview of your system's health and performance. This simplifies troubleshooting, optimizes resource use, and ensures consistent performance. Rancher emphasizes this simplification, highlighting better control, monitoring, and consistency. Likewise, Azure Kubernetes Fleet Manager focuses on simplifying multicluster management for Azure Kubernetes Service and Azure Arc-enabled Kubernetes, demonstrating the widespread recognition of fleet management's value.

Key Takeaways

Managing multiple Kubernetes clusters effectively requires a centralized strategy. Standardized configurations, automated workflows, and a single point of control simplify operations and reduce complexity.
Security and compliance are paramount in Kubernetes fleet management. Implement robust access controls, centralized policy enforcement, and comprehensive auditing to protect your infrastructure and meet regulatory requirements.
Plural streamlines Kubernetes fleet management by providing a unified platform that addresses key challenges. Features like GitOps deployments, Infrastructure as Code management, and a secure architecture empower organizations to scale their Kubernetes operations efficiently and securely.

Kubernetes Fleet Management Challenges

Maintaining Kubernetes clusters at scale is enough to drive any developer to the brink of frustration. The challenge intensifies when you consider that production-ready Kubernetes deployments involve multiple clusters across diverse environments, each running different distributions and managing various add-ons. As you expand your cluster footprint, the complexity of managing these clusters grows exponentially. While not surprising, it's an undeniable truth that demands attention.

Each element introduces additional complexity to the system, multiplied by the number of Kubernetes distributions, each with slightly different use models and capabilities that need to be understood.

Complexity of Managing Multiple Clusters

As companies grow, their Kubernetes needs evolve, often leading to a multitude of clusters spread across different environments and even cloud providers. Managing these clusters individually quickly becomes a tangled mess. Each cluster might have its own configuration, set of deployed applications, and monitoring tools. Keeping track of everything, from resource allocation to software updates, turns into a logistical nightmare. Without a centralized system, applying security patches or upgrading software becomes incredibly time-consuming and error-prone. As Google points out in their GKE documentation, managing numerous applications across various Google Cloud projects necessitates a solution like their 'fleets' feature to avoid overwhelming complexity.

Maintaining Consistency Across Environments

One of the biggest headaches in managing a Kubernetes fleet is maintaining consistency. You want all your clusters to behave predictably, regardless of location. This means ensuring consistent configurations, security policies, and application deployments across all environments. Azure Kubernetes Fleet Manager, for example, addresses this by centralizing management functions. This streamlines upgrades and configuration changes across the fleet, ensuring adherence to the same standards. Without this centralized control, you risk configuration drift, where individual clusters deviate from the desired state, leading to unpredictable behavior and potential security vulnerabilities. This inconsistency can also complicate troubleshooting and make it difficult to roll out new features or updates.

Security Concerns in Multi-Cluster Setups

Security is paramount in any IT infrastructure, and Kubernetes fleets are no exception. With multiple clusters, the attack surface expands, increasing the potential for vulnerabilities. Managing security policies and access control across a distributed fleet becomes significantly more challenging. Ensuring consistent security practices across all clusters is crucial. Google Kubernetes Engine (GKE), for example, offers tools for managing authentication across clusters and supports various identity systems, as highlighted in their documentation. A centralized interface is essential for maintaining a clear overview of security posture and ensuring compliance across the entire fleet. Without a centralized security management strategy, individual clusters might become weak links, jeopardizing the security of the entire system. This is especially critical for organizations operating in regulated industries with strict compliance requirements.

Why is Managing a Kubernetes Fleet so Difficult?

Throughout the past year, we have engaged in conversations with hundreds of engineering leaders to gather insights into the common challenges faced by organizations when it comes to effectively managing large fleets.

During our conversations, we noticed five themes repeatedly pop up.

It’s challenging to put guardrails in place for enterprise production environments (security, compliance, access controls, etc.). From a security standpoint, it is crucial to ensure that engineers have appropriate access levels. Without implementing granular permissions, your fleet management efforts would be highly vulnerable, increasing the risk of exposing critical infrastructure to unauthorized internal stakeholders.
There is a lack of expertise and headcount to manage and support Kubernetes. Currently, most companies use a variety of managed cloud services instead of relying strictly on Kubernetes. Consequently, their engineering teams ultimately lack the expertise to effectively manage workloads on Kubernetes. Acquiring Kubernetes talent is costly due to the limited availability of skilled engineers in this domain.
Kubernetes upgrades are not predictable since you don’t know what will break before it breaks. More often than not, Kubernetes upgrades don’t happen due to the complexity of upgrading clusters as you scale your cluster footprint.
There are inconsistencies when deploying software between dev, staging, and production environments. This often requires hand-rolling a tedious, complex git-based release process, and is manual enough that you can’t self-serviceably expose it to other teams. Existing tooling is built primarily for simple single-cluster deployment use cases out of a unique git repository and scalability and visibility challenges often arise when working with those tools. It is extremely challenging to test and confirm that your code changes are safe for your end users.
Developers are currently dedicating excessive time to configuring Kubernetes clusters instead of focusing on application development. The provisioning and maintenance of these clusters can be an incredibly laborious task. Moreover, specific clusters often require certain add-ons, which necessitate installation on each cluster. When you multiply this process by the number of clusters in operation, you gain a clear understanding of the manual nature of this process and the subsequent likelihood of increased human errors.

Lack of Centralized Control

As your Kubernetes fleet expands, managing numerous clusters individually becomes a significant operational burden. Each cluster may have its own configuration, access controls, and update schedules, leading to a fragmented management approach. This lack of centralized control makes it difficult to enforce consistent policies, perform fleet-wide updates, and maintain a clear overview of your Kubernetes landscape. Tools like Azure Kubernetes Fleet Manager aim to address this by centralizing tasks like upgrades and configuration changes. However, maintaining a truly unified view and control can be challenging, especially across multi-cloud or hybrid environments. Without a centralized management strategy, ensuring the reliability, security, and compliance of your entire fleet becomes increasingly complex.

Inconsistent Configurations and Deployments

Managing configurations and deployments across a large fleet can quickly become unwieldy without a robust management strategy. Inconsistencies across clusters can arise from various factors, including manual configuration changes, differing software versions, and varying access control policies. These inconsistencies create several problems. Troubleshooting becomes difficult, as the same application might behave differently across different clusters. Deployments are complicated, as you need to account for each cluster’s specific configuration. Finally, inconsistencies increase the risk of security vulnerabilities by creating exploitable loopholes. As Google Cloud points out, managing numerous applications across many clusters is complex, and inconsistencies exacerbate this. A consistent, automated approach to configuration and deployment is essential for effectively managing Kubernetes fleets.

Difficulty in Monitoring and Troubleshooting

Comprehensive visibility into the health and performance of your Kubernetes fleet is crucial for maintaining operational efficiency. However, monitoring and troubleshooting across a distributed set of clusters can be daunting. Without centralized monitoring and logging, identifying the root cause of issues can be time-consuming and complex. Correlating events across multiple clusters, dealing with different monitoring tools for each environment, and managing troubleshooting access all add to the challenge. Solutions like Plural’s secure Kubernetes dashboard and those offered by platforms like Rancher aim to provide detailed monitoring and control. Integrating these tools effectively across a diverse fleet requires careful planning and execution. A robust monitoring and troubleshooting strategy is essential for minimizing downtime and ensuring smooth operation.

Security Risks and Compliance Challenges

Security and compliance are paramount when managing Kubernetes fleets. Ensuring consistent security policies across all clusters, managing access control, and staying up-to-date with security patches are critical tasks that become increasingly difficult as your fleet grows. Inconsistent security configurations create vulnerabilities, while a lack of centralized access control can expose your clusters to unauthorized access. Furthermore, meeting compliance requirements, such as those mandated by FedRAMP, becomes more complex with a larger fleet. As we’ve discussed in previous posts on Day 2 Kubernetes, granular permissions are crucial for minimizing security risks and ensuring only authorized personnel can access and manage your clusters. A comprehensive security and compliance strategy, incorporating tools like OPA Gatekeeper for policy enforcement and automated vulnerability scanning, is essential for protecting your Kubernetes fleet and meeting regulatory requirements.

5 Key Principles of Kubernetes Fleet Management

When developing your fleet management strategy, it's crucial to consider five key tenets. While the priority of these tenets may vary, every organization, especially those in regulated industries, will eventually need to address all five. An ideal fleet management solution would encompass these pillars within a centralized platform, allowing you to efficiently manage all your fleets through a single interface.

Fleet management rests upon five crucial tenets: Governance, Simplicity, Visibility, Automation, Security.

In the following sections, we will delve into each of these pillars, drawing insights from our conversations with numerous engineering leaders over the past year.

Principle #1: Consistent Governance

To grow your Kubernetes fleet, it's critical to establish guardrails that ensure compliance with security policies and regulations. A Kubernetes fleet management platform should provide enterprise-ready permissions, avoiding oversharing critical infrastructure. Differentiate access levels based on roles to mitigate risks.

Centralized Policy Enforcement

Centralized policy enforcement is a cornerstone of effective Kubernetes fleet management. As your organization scales its Kubernetes footprint, managing policies across numerous clusters can quickly become unwieldy. A centralized approach, like that offered by Azure Kubernetes Fleet Manager or Google's Fleet management solution, streamlines this by allowing you to define and apply policies from a single control plane. This eliminates manual policy application on individual clusters, reducing inconsistencies and human error. Think of it as setting the rules once and having them automatically applied everywhere, ensuring compliance and security across your entire fleet. With Plural, you can leverage our agent-based architecture to enforce policies consistently across all managed clusters, regardless of their underlying infrastructure.

This centralized control is crucial for security and compliance. By defining access controls, resource quotas, and security profiles at the fleet level, you ensure all clusters adhere to organizational standards. This simplifies management and strengthens your security posture by minimizing misconfigurations or unauthorized access. Centralized policy enforcement also enables faster incident response. If a vulnerability is discovered, you can quickly apply a mitigating policy across your entire fleet, limiting the security issue's impact.

Standardized Configurations

Hand-in-hand with centralized policy enforcement is the need for standardized configurations. Managing a fleet of Kubernetes clusters effectively requires consistency across environments. Standardized configurations, achievable through automated tools like Azure Kubernetes Fleet Manager, simplify upgrades and maintenance by ensuring all clusters run on similar setups. This reduces complexity and makes troubleshooting easier, as you are dealing with a predictable and uniform environment. Imagine needing to update a specific software version. With standardized configurations, you can deploy that update across your entire fleet confidently, knowing it will behave consistently on every cluster. This also streamlines deployments. By using predefined templates and configurations, you can quickly spin up new clusters pre-configured to your specifications. This eliminates manual configuration, saving time and reducing errors.

This consistency is especially valuable in CI/CD pipelines, where predictable deployments are essential for reliable software delivery. Plural's Global Services feature lets you define and deploy standardized configurations across your fleet, ensuring consistency and simplifying management.

Principle #2: Operational Simplicity

Finding talented Kubernetes engineers is challenging and expensive. Kubernetes has a steep learning curve, and many developers prefer focusing on designing systems and implementing business functionality rather than handling DevOps. A fleet management platform should be easily adaptable, regardless of Kubernetes proficiency and team scale. In a recent conversation, a Head of Software Engineering referred to this scenario as a "shift-down" solution. The objective is to transfer maintenance responsibility away from staff-level engineers down the chain, allowing them to focus on core business functionality.

Automated Workflows

Automating workflows is key to efficient Kubernetes fleet management. Manually managing permissions across a large fleet isn’t just tedious—it’s a security risk. A robust platform should offer enterprise-ready permissions that prevent oversharing of critical infrastructure. Role-based access control (RBAC) is essential, allowing you to define granular permissions based on team responsibilities. This streamlines operations and significantly reduces the risk of unauthorized access.

Automation extends beyond permissions. A good fleet management platform will automate software deployments, ensuring consistency across all your clusters. This eliminates the manual effort and potential for error associated with traditional deployment methods. Automated workflows also play a crucial role in incident response. By automating tasks like scaling resources or restarting failed services, you can minimize downtime and ensure application availability.

Simplified Cluster Operations

Kubernetes can be complex. Finding and retaining skilled Kubernetes engineers is a challenge. Even experienced developers can get bogged down in operational details. A well-designed fleet management platform simplifies these complexities, allowing your teams to focus on building and deploying applications instead of wrestling with infrastructure. This "shift-down" solution delegates operational responsibilities, freeing up senior engineers for more strategic work. Simplifying operations is crucial for scaling your team effectively.

This simplification can manifest in several ways. A good platform provides an intuitive interface for managing clusters, abstracting away much of the underlying Kubernetes complexity. It might also offer pre-built templates and configurations for common tasks, further reducing the learning curve and accelerating deployments. Simplified cluster operations also mean easier troubleshooting. Centralized logging and monitoring tools can provide a clear view of your entire fleet, making it easier to identify and resolve issues quickly.

Principle #3: Enhanced Visibility

Managing a fleet of Kubernetes clusters requires visibility. As you expand to multiple clusters across different environments, complexity grows exponentially. Coordinating components, managing dependencies, and ensuring compatibility become intricate. Before upgrading, understanding deprecated resources and potential issues is crucial. Kubernetes has many moving pieces, making it challenging to predict what will break until it does. A single pane of glass view of clusters and services helps monitor resources and cluster health.

Centralized Monitoring and Logging

As your Kubernetes fleet expands across different environments—dev, staging, production, and beyond—effectively coordinating components, managing dependencies, and ensuring compatibility becomes increasingly intricate. Without centralized monitoring and logging, troubleshooting issues can quickly devolve into a chaotic scavenger hunt across numerous clusters and disparate logs. A centralized platform simplifies this by aggregating logs and metrics from all your clusters into a single, unified view. This streamlines troubleshooting and provides valuable insights into the overall health and performance of your fleet. Imagine having all your logs readily searchable and correlated, allowing you to pinpoint the root cause of problems quickly. This level of visibility is essential for maintaining the stability and reliability of your Kubernetes deployments.

Real-time Insights into Cluster Health

Kubernetes is a dynamic system with many moving parts, making real-time insights into the health of your clusters paramount, especially before upgrades. As discussed in our post on the 5 Key Principles of Kubernetes Fleet Management, predicting what might break during an upgrade is often difficult. A centralized dashboard with real-time metrics and alerts on resource usage, pod status, and other key indicators helps you proactively identify and address potential issues. This level of visibility empowers you to make informed decisions about resource allocation, scaling, and other critical operational tasks. Understanding the current state of your clusters and quickly identifying anomalies is crucial for maintaining a healthy and performant Kubernetes fleet. This real-time view allows you to catch problems before they escalate, minimizing downtime and ensuring a smooth user experience.

Principle #4: Streamlined Automation

Managing Kubernetes becomes more challenging with kubectl commands and scripts for a few clusters. But as the cluster count grows, this approach becomes impractical. Automating and standardizing routine cluster and application operations allows effortless oversight of multiple clusters, minimizing misconfigurations caused by human error. Deploying software between environments should be a fully automated self-service experience. Developers can import Git repositories and deploy services on clusters with gated promotions to ensure trustworthy code.

Automated Deployments and Rollouts

As your Kubernetes footprint expands, managing deployments across multiple clusters becomes increasingly complex. Relying on manual processes or simple scripts quickly becomes unsustainable. Automating deployments and rollouts is crucial for effectively managing a Kubernetes fleet. Automation minimizes the risk of human error and ensures consistent deployments across all environments, from development to production. This frees up your team to focus on building and improving applications, rather than wrestling with deployment complexities. For example, imagine a scenario where you need to deploy a new version of your application to 50 different clusters. Doing this manually would be a logistical nightmare, but with automation, it becomes a simple, repeatable process.

A robust Kubernetes fleet management solution should offer a streamlined, automated deployment process based on GitOps principles. You should be able to define your desired state in Git, and the system should automatically deploy and manage your applications based on that configuration. This approach not only simplifies deployments but also provides a clear audit trail and makes it easier to roll back changes if necessary. Features like automated rollouts, canary deployments, and blue/green deployments provide fine-grained control over how your applications are updated, minimizing downtime and ensuring a smooth transition for your users. As highlighted in Plural's 5 Key Principles of Kubernetes Fleet Management, automating deployments transforms a complex, error-prone process into a self-service experience, empowering developers to deploy code quickly and reliably.

Infrastructure as Code (IaC)

Managing the underlying infrastructure of your Kubernetes fleet can be just as challenging as managing the applications themselves. Manually configuring servers, networks, and other resources is time-consuming, error-prone, and difficult to scale. This is where Infrastructure as Code (IaC) becomes essential. IaC allows you to define your infrastructure in code, making it easier to automate provisioning, manage changes, and ensure consistency across your environments. Just like with application deployments, a GitOps approach to IaC provides a clear audit trail and simplifies rollback procedures. For instance, if a configuration change introduces an unexpected issue, you can quickly revert to a previous state using your Git history.

When choosing a Kubernetes fleet management solution, look for one that integrates seamlessly with your IaC tools, such as Terraform, Ansible, or Pulumi. This integration should allow you to manage your entire infrastructure, from the underlying servers to the Kubernetes clusters themselves, through a single platform. A good fleet management solution should also provide robust access controls and permissions for your IaC, ensuring that only authorized personnel can make changes to your infrastructure. This is particularly important in enterprise environments, where security and compliance are paramount. As Plural emphasizes in its 5 Key Principles of Kubernetes Fleet Management, granular permissions are essential for mitigating risks and ensuring the security of your infrastructure. This principle is crucial for organizations operating under strict regulatory requirements, such as those in the financial or healthcare sectors.

Principle #5: Robust Security

Maintaining accurate configuration and alignment across multiple clusters can be challenging. This becomes more complex with different workloads and Kubernetes distributions. Integration with existing SSO, effective authorization management through RBAC, and establishing a comprehensive audit trail are crucial. Currently, maintaining a secure environment is a manual effort, with teams managing access controls, network policies, and other security configurations. Effective auditing in Kubernetes is vital for visibility and control over cluster activity. Logging is pivotal in securing production clusters, requiring a robust audit mechanism. A complete audit trail is needed to track unauthorized events, including changes to sensitive files and their authors.

Access Control and Authentication

In Kubernetes fleet management, access control and authentication are non-negotiable. As discussed in Why You Shouldn’t Overlook Day 2 Kubernetes, providing every engineer with unrestricted access is risky. Granular permissions are crucial. Just as not every employee needs access to sensitive financial data, not every engineer requires access to every Kubernetes cluster. Role-based access control (RBAC) is key. Defining roles and assigning permissions based on those roles minimizes unauthorized access and potential security breaches. This granular approach ensures engineers only access necessary resources, limiting the impact of any security incident.

Security Auditing and Compliance

Securing and ensuring compliance for your Kubernetes fleet requires more than just access control. You need comprehensive visibility into cluster activity. This means robust auditing and logging, providing a detailed record of every action, change, and the user responsible. This becomes even more critical when managing multiple clusters, diverse workloads, and different Kubernetes distributions. Integrating with your existing single sign-on (SSO) solution streamlines authentication and user management. Using RBAC for authorization ensures appropriate access levels. A comprehensive audit trail provides the visibility needed to track activity, identify anomalies, and demonstrate compliance. Without these measures, maintaining a secure and compliant environment becomes a constant, manual effort, with teams struggling to manage access controls, network policies, and other security configurations across a complex and dynamic infrastructure.
