Kubernetes Troubleshooting: 7 Must-Know Commands for 2025

Running a Kubernetes cluster is like managing a complex orchestra—every component must work in harmony for the entire system to function smoothly. But even the most well-orchestrated systems can face hiccups. As a digital marketing strategist, I've seen how critical it is for businesses to maintain a robust digital infrastructure. Just like a brand needs to stay agile and responsive, so too must your Kubernetes environment be ready to adapt and recover from issues. In 2025, the ability to troubleshoot efficiently will be a key differentiator for any tech-driven business.

A Strategic Cpluz Perspective

At Cpluz, we've worked with multiple clients in the tech space, helping them navigate the complexities of cloud-native environments. One thing we've consistently observed is that the most successful teams are those that treat troubleshooting not as an afterthought, but as an integral part of their operations. In 2025, the pace of digital transformation is only accelerating, and having a toolkit of essential Kubernetes commands can save you hours of downtime and frustration.

Our team has developed a framework for troubleshooting that focuses on three pillars: visibility, control, and automation. By mastering these seven essential commands, you’ll be well-equipped to maintain the stability and performance of your Kubernetes clusters. Let’s dive into the commands that every modern DevOps professional should know.

What Are the 7 Must-Know Kubernetes Troubleshooting Commands?

When something goes wrong in a Kubernetes cluster, the first step is to gather information. These commands provide insight into the health of your pods, services, and nodes, helping you quickly identify and resolve issues.

1. kubectl get all

One of the simplest yet most powerful commands in your troubleshooting toolkit is kubectl get all. This command retrieves a snapshot of all resources in your cluster, including pods, services, deployments, and nodes. It's a great starting point for identifying any anomalies or unexpected states.

For example, if a pod is in a CrashLoopBackOff state, this command will help you spot it immediately. You can then drill down further with more targeted commands like kubectl describe pod or kubectl logs.

2. kubectl describe pod

When a pod is not running as expected, kubectl describe pod provides detailed information about its status, events, and configuration. This command is invaluable for understanding why a pod might be failing to start or crashing repeatedly.

For instance, you might see an error related to a missing image or a failed container. Armed with this information, you can take corrective action, such as rebuilding the image or adjusting the configuration.

3. kubectl logs

Logs are the backbone of any troubleshooting process. The kubectl logs command allows you to view the logs of a specific pod or container, giving you insight into what’s happening inside your application. This is especially useful for diagnosing runtime issues or errors that occur during execution.

For example, if your application is throwing an exception or failing to connect to a database, the logs will help you pinpoint the exact cause. You can also use this command to monitor the behavior of your application in real time.

4. kubectl top

Performance is a critical factor in any production environment. The kubectl top command gives you real-time metrics about resource usage, such as CPU and memory consumption, across your nodes and pods. This helps you identify any resource bottlenecks or overutilization issues.

By monitoring resource usage, you can ensure that your applications are running efficiently and that your cluster is not being overburdened. This is especially important as your workload grows and your cluster scales.

5. kubectl get events

Events provide a chronological record of what’s happening in your cluster. The kubectl get events command lists all events, including pod creation, deletion, and failures. This command is useful for tracking down issues that may have occurred in the past or for identifying recurring problems.

For instance, if a pod keeps restarting, the events will show you the exact time and reason for each restart, helping you diagnose and resolve the underlying issue.

6. kubectl api-resources

Understanding the resources available in your Kubernetes cluster is essential for effective troubleshooting. The kubectl api-resources command lists all the available resources, including their types, short names, and API versions. This helps you ensure that you're using the correct commands and resources for your specific setup.

By knowing what resources are available, you can avoid common mistakes, such as using the wrong resource type or referencing a non-existent resource.

7. kubectl get services

Services are the backbone of communication within a Kubernetes cluster. The kubectl get services command provides a list of all services in your cluster, including their endpoints and ports. This is particularly useful for troubleshooting network-related issues or connectivity problems.

If your application is unable to reach a service, this command will help you verify whether the service is running and whether it’s properly exposed to the rest of the cluster.

Frequently Asked Questions

Q: Are these commands applicable to all Kubernetes versions?
A: These commands are generally compatible with most Kubernetes versions, but it's always a good idea to check the specific documentation for your version to ensure compatibility.

Q: What if I don't have access to the Kubernetes dashboard?
A: You can still use these commands directly in your terminal or through a CLI tool like kubectl. The dashboard is a helpful visual tool, but the command-line interface offers more granular control.

Q: How often should I run these commands?
A: It's best to run these commands regularly as part of your monitoring and maintenance routine. They can also be used on-demand when you suspect an issue is occurring.

Q: Can I automate these commands?
A: Yes, many of these commands can be automated using scripts or monitoring tools, allowing you to proactively detect and resolve issues before they impact your application.
