Proof of concept setup for Wordpress running under PHP-FPM with an Nginx frontend

Usage

Build a copy of this image:

git clone git://github.com/d9206eacb5a0ff5d6be0.git docker-nginx-fpm
cd docker-nginx-fpm
docker build -t nginx-fpm .

Description

This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.

The script is here:

#!/bin/bash
convert "$1" -morphology Convolve DoG:15,100,0 -negate -normalize -blur 0x1 -channel RBG -level 60%,91%,0.1 "$2"

Results

3 x Cluster on AWS

manager1
worker1
worker2

Docker-machine commands

Use docker-machine to lay down 3 x hosts on AWS using docker-engine 1.12

docker-machine create --driver amazonec2  --amazonec2-private-address-only --engine-install-url https://test.docker.com/ levenson-docker-swarm-manager1 
docker-machine create --driver amazonec2  --amazonec2-private-address-only --engine-install-url https://test.docker.com/ levenson-docker-swarm-worker1

Every so often I have to restore my gpg keys and I'm never sure how best to do it. So, I've spent some time playing around with the various ways to export/import (backup/restore) keys.

Method 1

Backup the public and secret keyrings and trust database

cp ~/.gnupg/pubring.gpg /path/to/backups/
cp ~/.gnupg/secring.gpg /path/to/backups/
cp ~/.gnupg/trustdb.gpg /path/to/backups/

or, instead of backing up trustdb...

the grand idea

I like public key auth. I feel safer using them instead of a username and password login. But, I might not have my private key with me at a time where I need access.

I started using yubikey with LastPass and since I have it always on my keychain, I decided to find more ways to make use of it.

I wasn't originally aware, but if you pass a private key to ssh and sshd is configured to accept a key, it appears pam isn't used. Your authorized keys are checked and you are logged in. If you don't pass a private key, ssh falls back to the more standard un*x style login found in /etc/pam.d/sshd. This is where we'll add the yubikey pam. I am currently unaware of a way to use both public key auth and yubikey for login.

These steps worked for me on debian squeeze/wheezy.

Simple Two-Factor SSH Authentication

Posted on September 23 2011 by Richard Taylor (@moomerman)

In a two-part post I'm going to show you some tricks you can do with SSH logins. This post covers setting up two-factor SSH authentication with the Google Authenticator app.

I was recently getting some servers in shape so I can pass the Payment Card Industry standards questionnaire and one requirement was two-factor authentication access to the server. I queried whether SSH key + passphrase was acceptable but didn't get a clear answer so I figured I'd explore setting up another authentication factor myself, plus it piqued my interest.

After a bit of research I found it was possible using a PAM module but it doesn't work along with SSH key authentication (only password authentication) and I only use SSH key logins for my servers.

Docker Registry API V1 walkthrough

Matthew Riley ([email protected])

This document summarizes the interactions between the Docker client and the Docker Hub during push and pull commands through version 1 of the registry API. It was compiled to aid in writing a compatible registry server implementation after the existing API documentation proved occasionally incomplete or inaccurate.

Behavior and code links were as of Docker v1.2.0.

docker {push|pull} H:P/R[:T]
Host, Port, Repository ([namespace/]image), Tag

	#!/bin/bash
	set -e

	function handle_event() {
	local entry="$1"
	local action=$(echo $entry \| jq -r '.action')
	local service=$(echo $entry \| jq -r '.service')
	local hook="./hooks/$service/$action"
	if [ -x "$hook" ]; then
	"$hook" "$entry"
