Nope, not my position at all. I want to have a minimal OS environment with rudimentary tools available with zero extra friction. FROM alpine:latest adds less than 10MB and covers 95% of use cases. Typically depending on the container I will often throw in curl and some other QoL tools too.

For the rare cases where you find yourself needing to attach a debugger to your pods running in staging/prod, a debug container is absolutely the right tool to reach for.

How wasteful though? I have to admit, I envy the person whose codebase itself they have to support is so lean and space-conservative that the size of the gnu coreutils, curl, nano, etc., would show up as anything but a rounding error in the image size.

I see it like putting a thermometer in a turkey before I stick it in the oven. Sure, the thermometer adds thermal mass itself, making the turkey take a few seconds longer to cook, but the value of it being there is greater than the cost imposed.
