With the adoption of Kubernetes grows the number of specialists that interact with K8s clusters on daily basis. Some of those engineers introduce their own customized tools designed to simplify and automate their daily operations with the clusters.

 

Most of these tools are CLI utilities, with some working as kubectl wrappers or plugins to extend the functionality of kubectl. For example, kubectx and kubens allow for quick switching between kubectl contexts and namespaces within a cluster, while kube-ps1 indicates the actual context and namespace.

 

Kubectl-aliases provides nearly 800 programmatically generated kubectl aliases to avoid excessive verbosity in command strings. The kube-prompt client features convenient interactive autocomplete using prompts built in Go. The list could go on; more information could be found here.

 

There are also tools with more advanced functionality. For example, K9s, a terminal based UI, allows real-time tracking of cluster resources and activities, which makes it an alternative of a K8s dashboard. Stern provides for the advanced log analysis, as it enables tailing of multiple pods and containers at once. Each result is color coded for quicker debugging.

 

In the table below we have gathered the most popular CLI utilities and plugins with a brief stats showing the project health on GitHub.

As Kubernetes itself, these client tools are open-source and could be installed from their Git repositories. Hope you will find something useful here!
