As the use of Kubernetes continues to increase and become the go-to choice for container orchestration, companies are actively seeking out developers who possess the necessary skills to work with this technology. To be successful as a Kubernetes programmer, it is essential not only to have a thorough understanding of the concepts behind Kubernetes, but also to be able to work effectively and efficiently. To make things easier for developers, we have gathered a list of the top tools related to Kubernetes development that can help increase productivity.
Utilising Kubernetes in 2022
Kubernetes is a powerful system designed to orchestrate the deployment, scaling, and operations of containerized applications across a distributed network of servers. By monitoring the health of your application, it can prevent instances from being destroyed simultaneously, allowing you to reap the full benefits of containerization.
Several Kubernetes instruments are discussed here. The functions they provide have guided our classifications. Specifically, we’ll be discussing:
- Command-Line Interface Programs for Kubernetes
- Tools for keeping tabs on Kubernetes
- Kubernetes safety applications
- Setup instruments for Kubernetes
Okay, so let’s begin!
CLI instruments for Kubernetes
The acronym “CLI” stands for Command Line Interface, which is an essential utility for controlling Kubernetes deployments. The original document concerning this has been divided into two parts for further examination.
- The binary kubectl: Used for communicating with Kubernetes clusters
- Indicator of the kubelet binary: Typically used to control the various servers that make up a Kubernetes cluster.
Using the CLI, you can:
- Rather than utilising the web-based user interface, you may directly communicate with Kubernetes.
- Apply automation to many Kubernetes environments.
- Care for clusters’ data and their connections to the outside world.
Key command-line interface (CLI) tools for Kubernetes include:
K9 is a powerful Kubernetes utility designed to facilitate communication between nodes within a Kubernetes cluster. It provides users with a Command Line Interface (CLI) and an Application Programming Interface (API) for the centralised control of Kubernetes deployments. Its advanced features include port forwarding and YAML object inspection, which can be easily accessed through its intuitive and user-friendly interface.
K9 information that gets less attention:
- You can find the source code for K9 on GitHub.
- The Go language is used for K9’s development, and it’s released under the Apache 2.0 open-source licence.
two words: kubectx and kubens
It is possible to quickly switch between different Kubernetes contexts and namespaces using the tools kubectx and kubens. These tools make it unnecessary to remember the various details of each cluster, allowing for a streamlined transition between them.
Kubernetes clusters can be managed from the command line using the kubectl tool. This tool offers a range of capabilities, including application deployment, cluster resource analysis and management, and log analysis. Utilising the kubectl tool, users can access and interact with their Kubernetes clusters in an efficient and effective manner.
Finding and managing Kubernetes-specific plugins is made easier with kubectl krew plugin management.
Kubernetes stores its configuration data in a key-value database store called etcd. As such, it is an integral part of Kubernetes.
Commonly used alternative Kubernetes CLI programs:
- kube-apiserver: There is a Kubernetes API server that makes the Kubernetes API available. Kubernetes’ primary interface with the rest of the world is its API server.
- Kube-controller-manager: Controllers in Kubernetes are managed by a daemon called the controller manager, which resides on the master node.
- Kube-scheduler: The Kubernetes scheduler, a kind of domain controller, is responsible for allocating worker node time to execute pods.
Tools for keeping tabs on Kubernetes
By leveraging a comprehensive set of tools, it is possible to stay informed about the health and performance of a Kubernetes cluster. These tools can be used to monitor the condition of a cluster as a whole, as well as its components, such as nodes, pods, and services. Additionally, these tools can be utilised to detect and remedy Kubernetes-specific issues.

Kubernetes safety applications
It is essential to safeguard your containers from unauthorised access and maintain their security. Kubernetes provides various security features that can be employed to accomplish this goal. These features can be used to ensure that only approved users are able to access the containers. Additionally, Kubernetes tools can be employed to monitor the containers and conduct audits to detect any existing vulnerabilities.
When it comes to safeguarding your Kubernetes cluster, there are several effective solutions available. Kube-hunter, Kube-Bench, Aqua Security, and Twistlock are some of the most widely recognised and trusted options. Each of these solutions provide powerful protection for your Kubernetes cluster, enabling you to detect and respond to potential threats quickly and efficiently.
In 2022, these Kubernetes security tools are a need.
This instrument enables users to detect and address security vulnerabilities in Kubernetes clusters. After performing a scan of the cluster, a report is generated to highlight any potential security issues and to provide constructive advice on how to rectify them. Moreover, this instrument can be incorporated into a CI/CD (continuous integration/continuous deployment) pipeline, thus allowing for automated scans of the cluster.
This useful tool is designed to ensure secure installation and configuration of Kubernetes. The Centre for Internet Security (CIS) sets standards for the system, and this tool runs a series of tests to verify that the Kubernetes cluster meets these standards. Furthermore, this tool offers the following additional advantages:
