This article explains how the minimalist philosophy of containers leads to missing tools, discusses early ideas of host‑based debugging, and shows how Kubernetes introduced the kubectl debug command with temporary containers to run any missing binaries directly inside pods.
This article explains why traditional kubectl exec fails under common Kubernetes security best‑practices and demonstrates how to use kubectl debug to launch temporary containers with shared namespaces, install tools like htop, and explore alternative debugging methods such as kpexec and AI‑assisted Appilot.
This guide explains why kubectl exec often fails under security best practices, introduces kubectl debug for creating ephemeral containers with root access, and explores additional methods such as kpexec and Appilot to troubleshoot running pods in Kubernetes clusters.
This guide explains why exec‑based pod debugging is limited and demonstrates how to use Kubernetes ephemeral containers to troubleshoot network issues, trace processes, and debug nodes without restarting the pod, including step‑by‑step commands and code examples.
This article explains how to debug live Kubernetes pods using temporary (ephemeral) containers that share namespaces, covering cluster setup, creating workloads, diagnosing network problems, tracing processes, and accessing node shells without restarting the original pods.
This article explains why minimal container images hinder debugging, introduces Kubernetes Ephemeral Containers as a solution, and provides detailed commands and examples for enabling the feature, launching temporary containers, sharing process namespaces, and performing advanced troubleshooting.
