What’s up Doc(ker)?

A recent post from Doug Davis “Docker: Managing the excitement” has some nice insights on Docker as a “relatively new” technology. Among the other Docker niceties that Doug points out, one that resonated with me is, and I quote “it takes seconds (if not less than a second, after the first time since things are cached) for it to complete”. Reading between the lines in some of my other posts, I’ve often battled the dark forces of virtual machine world, usually trying to squeeze every bit of extra juice out of my poor laptop. Then I tried Docker and well, suffice to say I need fewer coffee breaks.

My long-time colleague and friend Takehiko Amano has a post on “Immutable Infrastructure” where he talks about Docker in the context of OpenStack and with a bunch of my earlier posts focused on OpenStack, I decided to figure out how the three – OpenStack, Docker, and UCD+P might work together.

UrbanCode Deploy with Patterns: Hello World, the vSphere edition

In the concluding paragraphs of my last post, UrbanCode Deploy with Patterns: Hello World ,I briefly compared the UrbanCode Deploy with Patterns (UCD+P) use of OpenStack HEAT Templates (HOT) for blueprints with my own simple XML blueprint for vSphere compute resources.  In the past week a Fix Pack was released for UCD+P which adds initial support for provisioning to VMware vSphere infrastructure. So in this post I’ll do a “Hello World” -style example of connecting UCD+P to a vCenter 5.5 server, provisioning a VM on it and deploying multiple UrbanCode Deploy (UCD) components to the VM.

Connecting UrbanCode Deploy with Patterns to OpenStack

UrbanCode Deploy with Patterns (UCDP): a mouthful right? A pretty neat and powerful mouthful though. Consider theses two posts: Cooking up deployments on stacked clouds and UrbanCode Deploy with vSphere and Chef. UCDP makes it simpler and easier to carry out a bunch of steps detailed in those posts. Before I get into the details, let me first quickly go through how to install UCDP and connect it to an OpenStack setup.

HTTP Value Sets in UrbanCode Deploy

Remember that old,old post of mine: HTTP Filtered Value Set Providers and dependent enumerations ? Probably not. It goes into a little feature of Rational Team Concert that makes it easy to avoid having to duplicate data from external systems that RTC might need to integrate with. UrbanCode Deploy can do something similar for value sets for process properties.

UrbanCode Deploy with vSphere and Chef

In a previous post (Cooking up deployments on stacked clouds) I looked at using UrbanCode Deploy with OpenStack and Chef. I showed one way of creating a stack from a Heat template, injecting the UCD agent and Chef  into one of the newly provisioned servers, cooking a Chef recipe and deploying an application on it. This time round I look at how to do almost the same thing with VMware vSphere.
