Using Eucalyptus 4.0.1 CloudFormation to Deploy a CoreOS (Docker) Cluster

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 CloudInit Config for Docker Storage Management

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 […]

Yet Another AWS Compatibility Example Using Vagrant-AWS Plugin and Eucalyptus 3.4 to Deploy Docker

Something that Eucalyptus has been constant about from the beginning is its stance on being the best open source, on-premise AWS-compatible cloud on the market.   This blog entry is just another example of demonstrating this compatibility. My most recent blog entries have been centered around Docker and how to deploy it on Eucalyptus.  This entry […]

Cloud Image Management on Eucalyptus: Creating a CentOS 6.6 EMI With ZFS Support

ZFS is a filesystem designed by Sun Microsystems that focuses on data integrity.  What makes this such an attractive filesystem to use in the cloud is that a cloud user can easily do the following: set up an LVM + RAID filesystem for storing large amounts of data (e.g. database information) expand the filesystem by adding […]

Setting Up 3-Factor Authentication (Keypair, Password, Google Authenticator) for Eucalyptus Cloud Instances

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 […]

Growing and Securing Instance Root Filesystems With Overlayroot on Eucalyptus

Background I frequently check out Dustin Kirkland’s blog to get ideas about how to secure instances running on various cloud infrastructures.  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 […]
