alt Hacker NewsYup! They are a good solution to the massive problem you caused for yourself by implementing a different "solution" to a non-problem.
And even that's only true if you assume kubernetes is the only place your container runs where you might want to also debug it.
You want to ship every debug utility you will need in every image? Just seems wasteful. What about 3rd party images, you will respin images just to add your preferred toolset?
