  • Kubernetes monitoring tools
  • Kubernetes security tools
  • Kubernetes deployment tools

Let's get started!

Kubernetes CLI tools

Kubernetes CLI tools.webp

CLI in Kubernetes stands for Command Line Interface. It is a tool for managing Kubernetes clusters and applications. It has split into two sections:

  • The kubectl binary: Used to interact with Kubernetes clusters
  • The kubelet binary: Used to manage the individual nodes in Kubernetes clusters.

CLI allows you to:

  • Communicate with Kubernetes without using the web UI.
  • Automate processes across several Kubernetes clusters.
  • Handle storage and networking of clusters.

Here are some must-have Kubernetes CLI tools:

  • Kibana: An open-source visualization tool to create dashboards to visualize your log data. It is highly customizable and can create personalized dashboards.

Kubernetes security tools

With Kubernetes security tools, you can prevent unauthorized access to your containers and ensure that only authorized users have access. The tools also help monitor and audit your containers, allowing you to detect any security issues.

There are several tools available to assist with securing your Kubernetes cluster. The most popular ones include kube-hunter, kube-bench, Aqua Security, and Twistlock.

Here’s a look at these must-have Kubernetes security tools in 2022.

kube-hunter

This is a tool for detecting security flaws in Kubernetes. It scans a Kubernetes cluster for potential security issues and provides a report with recommendations for mitigating those issues. It can run automatically as part of a continuous integration/continuous deployment (CI/CD) pipeline.

kube-bench

It helps check whether Kubernetes is deployed securely. It conducts a series of tests against a Kubernetes cluster to certify that it fulfills the Center for Internet Security (CIS) benchmarks. It benefits include:

  • Aiding in the safe installation of Kubernetes without additional keys.
  • Can be executed automatically via the deployment pipeline.

Twistlock

Twistlock provides comprehensive security for your containers, including vulnerability management, runtime protection, and compliance monitoring. It makes it easy to deploy and manage Docker containers in any environment.

Twistlock is not an open-source security tool. It’s available in two editions:
