xcsrz / pageTimer.rb
Created November 5, 2014 20:23
Just a little script to time page requests (no assets, just the single URL). It runs via /usr/bin/ruby which is present on all macs and most posix systems these days. If you're using rvm you'll probably want to change that.
#!/usr/bin/ruby
$url = ARGV[0]
$rounds = ARGV[1] || 10
loadTimes = []
puts "fetching page #{$rounds} times ..."
$rounds.to_i.times do
print "."
loadTimes << (`curl -w '%{time_total}\n' -o /dev/null -s "#{$url}"`).to_f

If you run into a situation where you have thousands or tens of thousands of dead containers and you run the usual docker rm `docker ps -a -q` either docker will bomb saying too many arguments or you'll see that as the list of containers being killed grows the process slows down. It seems the docker process amasses all the open files until it's …
while [[ `docker ps -a -q | wc -l` -gt `docker ps -q | wc -l` ]]; do docker rm ` docker ps -a -q | head -n 25`; done

Last active October 28, 2015 23:19
This script creates the .key and .csr files using the bare minimum information. It's only argument is the domain name to be secured. Prepend "*." for wildcard domain certificates. Customize the DEFAULT_ORGNAME and DEFAULT_ORGCOUNTRY setting variables at the top before use. Environment variable overrides are ORGNAME and ORGCOUNTRY.
#!/bin/bash
DEFAULT_ORGNAME="xcsrz"
DEFAULT_ORGCOUNTRY="US"
if [ -t $1 ]; then
echo "you must provide a domain name (don't forget the asterisk if it's for a wildcard certificate"
echo ""
echo "Usage:"
echo " ${0} DOMAIN"

xcsrz / getInside.sh
Last active November 17, 2015 02:59
A bash function to get inside a running docker container ... still needs tweaking, requires nsenter ( https://github.com/jpetazzo/nsenter )
getInside() {
# pass in a container ID
CONTID=$1;
# This prints out export commands you can paste into the terminal once inside the container - not always needed
sudo docker inspect $CONTID | awk '/(PATTERN FOR ENV VARIABLES YOU CARE ABOUT)/ { gsub(/[",]/,"",$1); print "export " $1 } '
# Get the process ID
PID=$(sudo docker inspect --format {{.State.Pid}} $CONTID );
# Status message
echo "Entering container $CONTID with PID $PID";
# Enter the container
