ewsdocker/alpine-htop repository overview

⁠ewsdocker/alpine-htop

This is a very small (16 MB) Alpine Linux docker implementation of the htop example in the docker run reference (see below). It is a simple example of the use of the built-in PID Namespace (--pid=) Linux virtualization.

The Dockerfile for the alpine-htop image is short and simple, and can easily be entered from a console editor. However, I use this example a lot and have tired of entering it for each use. Hence, this image.
