thediveo / nsfdref.py

Created January 9, 2020 20:05

Demonstrates keeping namespaces alive by keeping an open fd for them, as well as how the discovery powers of "lsns" and "lsuserns" differ.

	# nsfdref.py
	#
	# Creates two network namespaces, referencing the first one by fd, and
	# showing the output of "lsns" versus "lsuserns". "lsuserns" is able
	# to discover the first network namespace from the fd which keeps the
	# namespace alive.
	#
	# Requires these Python3 packages:
	# - pip3 install unshare
	# - pip3 install python-prctl

thediveo / inversehierarchy.sh

Last active December 23, 2019 08:30

Can child(!) PID namespaces be owned by parent(!) user namespaces?

	#!/bin/bash

	# Test the hypothesis that PID namespace hierarchy cannot "run on reverse" to
	# the user namespace hierarchy. In particular, a PID child namespace cannot be
	# owned by a parent user namespace. However, a PID namespace can be a child of a
	# PID namespace owned by a parent user namespace.
	echo "trying to create a child PID namespace which is owned by a parent user namespace..."

thediveo / runwithkp.sh

Created July 12, 2019 18:29

Starts local Kubernetes API proxy and creates a suitable context, runs application, then stops the proxy after the application has finished.

	#!/bin/bash

	CONTEXT="minikube"
	PROXYCONTEXT="proxykube"

	function cleanup {
	kubectl config delete-context $PROXYCONTEXT 2>/dev/null
	kubectl config delete-cluster $PROXYCONTEXT 2>/dev/null

thediveo / transcode-raw-screenrecording.sh

Created May 16, 2019 19:45

Correctly transcode in-device Android screen recordings (which were created by ffmpeg), so that they can be correctly edited and processed further during post. In particular, enforces a fixed framerate and the correct color coefficients.

	#!/bin/bash
	# Correctly transcode in-device screen recordings from Android, so they
	# do not cause all kinds of mishaps later down the editing and rendering
	# pipeline. In particular, enforces a fixed framerate to avoid problems
	# with widely varying dynamic frame rates, which can go from anywhere
	# a frame every 10s of seconds to 100fps or so. Additionally, we
	# enforce the correct color coefficients for the transcoding to avoid
	# video tools to guesstimate completely nonsense transformation -- ffmpeg,
	# I'm looking at you here.
