Ubuntu, NetworkManager and Docker DNS workaround

Docker issues are frequently logged for DNS resolution in containers because it doens't inhert or get values for DNS from NetworkManager which leverages a built in dnsmasq to inteligently manage DNS.

Perminant workarround

sudo bash -c "echo listen-address=$(ip -4 addr show dev docker0 | grep -oP '(?<=inet\s)\d+(\.\d+){3}') > /etc/NetworkManager/dnsmasq.d/docker-bridge"
sudo systemctl reload NetworkManager
sudo bash -c 'echo -e "{\n\t\"dns\": [\"$(ip -4 addr show dev docker0 | grep -oP "(?<=inet\s)\d+(\.\d+){3}")\"]\n}" > /etc/docker/daemon.json'
sudo systemctl restart docker

Local Kubernetes setup on macOS with minikube on VirtualBox and local Docker registry

Requirements

Minikube requires that VT-x/AMD-v virtualization is enabled in BIOS. To check that this is enabled on OSX / macOS run:

sysctl -a | grep machdep.cpu.features | grep VMX

If there's output, you're good!

Adventures in Python Core Dumping

Adventures in Python Core Dumping

After watching Bryan Cantrill's presentation on [Running Aground: Debugging Docker in Production][aground] I got all excited (and strangely nostalgic) about the possibility of core-dumping server-side Python apps whenever they go awry. This would theoretically allow me to fully inspect the state of the program at the point it exploded, rather than relying solely on the information of a stack trace.

How does `ls` work?

How does ls work?

I wanted to be really able to explain to a fair amount of detail how does the program :command:`ls` actually work right from the moment you type the command name and hit ENTER. What goes on in user space and and in kernel space? This is my attempt and what I have learned so far on Linux (Fedora 19, 3.x kernel).

How does the shell find the location of 'ls' ?

Manage your PATH with a nice, one-directory-per-line file, rather than a gargantuan blob of colon-delimited text.
# Read the contents of ~/.path into $PATH, if ~/.path exists. ~/.path should be a file
# consisting of one path on each line, such as:
#
# ~$ cat ~/.path
# # vim: ft=sh
# ~/usr/bin
# /opt/local/bin
# ... etc ...
#
# Note that comments begin with a hash (#).
