In a previous blog, I discussed how cloud-init can be used to customize a CoreOS image deployed as an instance on Eucalyptus – which happens to work in the same fashion on AWS. This is a follow-up blog to demonstrate how to use Eucalyptus Cloudformation (which is in Tech Preview in Eucalyptus 4.0.0/4.0.1) to deploy a CoreOS […]
CoreOS is a Linux distribution that allows easy deployment of Docker environments. With CoreOS, users have the ability to deploy clustered Docker environments, or deploy zero downtime applications. Recently, I have blogged about how to deploy and use Docker on Eucalyptus cloud environments. This blog will focus on how to leverage cloud-init configuration with a CoreOS […]
In 2014, I created a series of blog posts that have discussed using CoreOS on Eucalyptus cloud infrastructures. This blog post is an updated version of the entry which discussed how to deploy a CoreOS cluster using a cloudformation template on Eucalyptus 4.0.1. It will cover how to deploy a CoreOS cluster using Cloudformation on […]
Introduction My last few blogs have discussed how Eucalyptus 4.0 supports similar Amazon Web Services, such as Elastic Compute Cloud (EC2), Simple Storage Services (S3), Elastic Load Balancing (ELB) and Security Token Services (STS) features. Using third party tools, such as python boto and s3cmd, features such as listing buckets and objects, listing running instances and assuming […]
Recently, I was logging into my AWS account, where I have multi-factor authentication (MFA) enabled, using the Google Authenticator application on my smart phone. This inspired me to research how to enable MFA for any Linux distribution. I ran across the following blog entries: Three-factor authentication with OpenSSH, Google Authenticator and Password | Today I […]

Recently, I stumbled across one of his blog entries, where he discussed a package called ‘overlayroot‘, which is part of the cloud-initramfs-tools package for Ubuntu. The really interesting feature I liked about this package […]
