Most Kubernetes debugging images ship as a single 200+ MB package. DebugBox takes a different approach: three variants (15 MB, 47 MB, 91 MB) each scoped to a specific debugging task. This tutorial covers when to use lite, balanced, and power, how to run each as an ephemeral container or debug pod, and what tools are available in each variant.
Learn how to edit a file in a running Kubernetes Pod when the container's user has no write access to it.
