Most Effective Kubernetes Development Resources for 2022

Kubernetes is now the preferred choice for container orchestration, and with its growing popularity, companies are keen to hire developers who are highly skilled in this technology. To excel as a Kubernetes programmer, it is crucial to have an in-depth grasp of Kubernetes concepts, and equally importantly, the ability to work efficiently and effectively. Our list of top Kubernetes development tools can be an asset to developers seeking to boost their productivity.

Using Kubernetes in 2022

Kubernetes is a robust system developed to handle the deployment, scaling, and operations of containerized applications over a distributed network of servers. By keeping track of your application’s health, it can prevent instances from being terminated simultaneously, enabling you to enjoy the complete advantages of containerization.

This article covers various Kubernetes tools. Our categorization is based on the specific roles they play. The tools we’ll be exploring include:

  • Kubernetes Command-Line Interface (CLI) Programs
  • Monitoring Tools for Kubernetes
  • Security Applications for Kubernetes
  • Setup Tools for Kubernetes

Alright, let’s get started!

Kubernetes CLI Tools

CLI stands for Command Line Interface and is a critical tool for managing Kubernetes deployments. In this article, we have divided the original document into two parts for further analysis.

  • The kubectl binary:

    Used to interact with Kubernetes clusters
  • kubelet binary:

    Typically used to manage the multiple servers that constitute a Kubernetes cluster.

With the CLI, you are able to:

  • Instead of using the web-based user interface, you can communicate directly with Kubernetes.
  • Implement automation across multiple Kubernetes environments.
  • Manage cluster data and its connections to external networks.

The essential command-line interface (CLI) tools for Kubernetes consist of:


K9 is a robust Kubernetes utility that simplifies communication between nodes within a Kubernetes cluster. It offers a Command Line Interface (CLI) and an Application Programming Interface (API) that enable centralised management of Kubernetes deployments. K9 also has advanced functionalities such as port forwarding and YAML object evaluation, both of which can be accessed easily through its intuitive and user-friendly interface.

Lesser-known details about K9:

  • The source code for K9 is available on GitHub.
  • K9 is developed using the Go programming language and is released under the Apache 2.0 open-source license.

Two Key Terms: kubectx and kubens

Switching between multiple Kubernetes contexts and namespaces can be done effortlessly using tools like kubectx and kubens. These tools eliminate the need to recall the specific details of each cluster, enabling a seamless shift between them.


Managing Kubernetes clusters can be achieved via the kubectl tool on the command line. This tool provides a multitude of functionalities such as application deployment, analysis and administration of cluster resources, and log evaluation. With the kubectl tool, users can efficiently and effectively access and interact with their Kubernetes clusters.

The kubectl krew plugin management system makes the search and management of Kubernetes-specific plugins more convenient.


The configuration data of Kubernetes is stored in a key-value database called etcd, making it a crucial component of the Kubernetes system.

Frequently used alternative Kubernetes CLI programs:

  • kube-apiserver:

    Kubernetes has an API server that enables access to its API. The API server serves as Kubernetes’ primary interface with the external world.
  • Kube-controller-manager:

    The controller manager, a daemon operating on the master node, manages the controllers in Kubernetes.
  • Kube-scheduler:

    The Kubernetes scheduler, which functions as a domain controller, is tasked with assigning worker node resources to execute pods.

Tools to Monitor Kubernetes

Employing a range of tools enables users to stay up-to-date on the status and effectiveness of their Kubernetes cluster. These tools can be utilised to monitor the condition of the cluster and its components, including nodes, pods, and services. Furthermore, they can assist in identifying and resolving any Kubernetes-related concerns.

For exceptional observability, consider using these recommended Kubernetes tools.


Prometheus is an open-source, no-cost monitoring tool used to monitor applications and services written in any programming language. Its use with Kubernetes provides numerous advantages, such as:

  • A user-friendly data model with substantial capabilities, allowing for easy and efficient measurement tools.

Grafana’s data-visualization tool provides an outstanding avenue for generating dashboards that exhibit metrics data. As one of the top Kubernetes visualization tools, it streamlines the process of visually representing data in an attractive and user-friendly fashion.

  • Support for numerous data sources, such as Prometheus.
  • Ability to incorporate various add-ons to enhance its functionality.
  • High versatility, allowing users to create their own dashboards.

Kubernetes Management Console

Kubernetes offers a pre-installed monitoring system, simplifying cluster and node management. By utilizing the Kubernetes Management Console, users can easily monitor key aspects such as CPU and memory usage, container health status, and access log data.

Access to the dashboard can be obtained via the kubectl command-line interface. Additionally, Kubernetes API can be utilized to obtain monitoring data programmatically, a shared approach for retrieving data.

Alongside these, several other open-source Kubernetes monitoring tools are available, including:

  • Fluentd:

    A log gathering tool that can collect and transfer log data to a centralised logging system. It is designed to be compatible with a broad range of data sources, including Prometheus.

Kubernetes Security Applications

Ensuring container security and preventing unauthorized access is crucial. To achieve this goal, Kubernetes offers numerous security features. These security features are designed to limit container access to authorized users only. Kubernetes tools can also monitor containers and conduct audits to identify any vulnerabilities that may exist.

Numerous reliable solutions are available to secure your Kubernetes cluster. Kube-hunter, Kube-Bench, Aqua Security, and Twistlock are among the most popular and trusted options. Each of these solutions provides robust protection for your Kubernetes cluster, enabling you to promptly detect and respond to potential threats.
