Just run this from your Mac terminal and it'll drop you in a container with full permissions on the Docker VM. This also works for Docker for Windows for getting in Moby Linux VM (doesn't work for Windows Containers).
docker run -it --rm --privileged --pid=host justincormack/nsenter1

Note: This is an older post that I did back when I thought I might have time to be a blogger. Oh I was oh so wrong. However, it has proven useful for some folks on stackoverflow. Thus I'm keeping it alive here on Gist.
One of my past projects dealt heavily with an open source Apple technology called HTTP Live Streaming. It’s an HTTP based streaming protocol that at its most fundamental level provides a way to stream video and audio from just about any server with nothing but a few free software tools provided by Apple**. However, it has a few additional features that I think make it a really exciting tool. Yet, I haven’t seen HTTP Live Streaming used very much. This is probably mainly due to the combination of a lack of good/clear documentation, and Apple’s Live Streaming Developer Tools being command line based also make the barrier to entry higher than many developers want to deal with.
The hope is to share my understanding of how to use this technology to:
