Kubernetes Tools

Know that Kubernetes tools simplify managing Kubernetes clusters. This is because managing Kubernetes clusters is not a simple task; it needs specific tools to streamline deployment, scale, and perform other crucial operations. The Kubernetes tools offer vital features such as ease of use, security, speed, quick deployment, and many more. Of course! In this blog, you will learn the purpose and features of the prime Kubernetes tools in a crisp way.

Undeniably, complexity is one of the limitations that can slow down any process – be it software development or any other. We need to use to right tools to simplify complexity or eliminate it altogether.

On that note, when it comes to large-scale software development, deployment and maintenance, no doubt complexity may arise at any stage. We must identify and use the right tools to resolve the complexity as fast as possible.

Know that Kubernetes is one of the robust container orchestration systems used to deploy automatically, scale, and maintain software applications. Complexity inevitably arises while dealing with large workloads in Kubernetes. However, there are a lot of Kubernetes tools that simplify managing Kubernetes in a significant way.

Yes! The goal of this blog is to walk you through the various Kubernetes tools listed based on different categories. Also, you will understand the purpose and the vital features of the tools in a quick way.

4. Monitoring Tools 

monitoring tools

  • Kubewatch

Kubewatch is also known as Kubernetes watcher. It watches Kubernetes clusters to identify changes in resources. In other words, this tool monitors Kubernetes events and trigger handlers. Any change in the resources enables notifications to external services such as collaboration hubs, webhooks, and notification channels. Not only limited to these, but this tool also publishes notifications through Slack, Mattermost, HipChat, flock, and so on.

  • Grafana

It is an open-source monitoring and analytics tool. With this tool, you can visualize metrics and logs of Kubernetes operations accurately. This tool encourages interaction of users, so users can query, retrieve, visualize, and infer the metrics in a straightforward way. Grafana allows creating your own dashboards. You can visualize metrics in graphs with the help of panel plugins. No wonder Grafana builds data-driven culture in organizations.

It is essential to note that Grafana enables notifications for abnormal changes in crucial metrics.

  • Prometheus

Prometheus is an open-source monitoring tool that issues alerts and notifications. So, it allows monitoring applications running on Kubernetes clusters. This tool allows configuring notifications as well. With this tool, you can gain high visibility across APIs, containerized applications, and other resources. Besides, you can identify irregular traffic in the clusters using this tool.

  • Dynatrace

It is yet another Kubernetes monitoring tool that comes with many merits. With this tool, you can identify the dependencies between microservices, resource consumption in Kubernetes clusters, the performance of applications, and many more. This tool provides the complete health and metrics of containers, nodes, pods, and clusters.

As this tool is AI-powered, it identifies anomalies in the clusters in real time along with the root cause of the anomalies. Above all, it quickly locates the failed or pending pods in the clusters.

5. Security Tools

Security Tools

  • Twistlock

It is a rule-based security tool for Kubernetes. This tool performs access control based on security policies. The main thing about this tool is that users can modify the security policies but can't delete them. This tool allows developers to use only verified images.

With Twistlock, you can track scanning the registries. As a result, you can quickly identify resource vulnerabilities and prioritize the risks to rectify them effectively.

  • Kamus

It is a secret management tool for Kubernetes. It works based on encryption and decryption methods. It uses encrypted secret values to improve the security of Kubernetes clusters.

It is essential to note that the applications that run only on Kubernetes can decode the secret values. For encryption, this tool uses encryption providers such as Google Cloud KMS, AES, Azure Keyvault, etc.

Another thing is that this tool tights the security of Kubernetes clusters by ensuring that the application for which the secret values are encrypted can only decrypt the secret values – not any other application.

  • Terrascan

This tool is used to secure Infrastructure as Code (IaC). By using this tool, you can control risks before provisioning cloud infrastructure using IaC. Thus, you can effectively detect security and compliance violations across IaC.

Security policies help to identify risks in IaC. Over 500 policies are used for this purpose. It is essential to note that this tool uses Open Policy Agent (OPA) to generate custom policies based on the Rego query language.

6. Deployment and CLI Tools

Deployment and CLI Tools

Even you can view the breakdown of costs for service, deployment, etc. This tool also offers insights and recommendations to boost the efficiency and reliability of Kubernetes clusters, intelligently.

  • Loftlabs

It is yet another cost-management tool that helps to reduce costs. For this, this tool uses the automatic sleep mode. When none of your team members uses Kubernetes clusters, they shift to idle mode, automatically. You can control cluster resources with the multi-cluster and multi-cloud options. With the multi-region option, this tool prevents roundtrips and reduces latency as short as possible.

8. Components Tools

Components Tools

Generally, node components run on every node in the Kubernetes cluster. They are used to maintain running pods. They also offer a Kubernetes runtime environment.

  • Kubelet

It is a tool that runs on all the nodes in a Kubernetes cluster. This agent ensures that every container is running in a pod. Here, Pod is nothing but a component of workloads. This agent must ensure containers are running as per expectations. The expectations are usually described in PodSpecs. Note that this tool manages only the containers created by Kubernetes.
