DEVOPS WEEKLY ISSUE #247 - 27th September 2015

3 minute read

I attended the first WinOps conference this week, focused on Devops practices in Windows environments. The interesting part was how much of the audience was new to everything Devops - it’s worth remembering that if you’re thinking about writing or talking about something and not sure what to cover. We still need lots more good introductory material out there.

Inspired by the famous 6th century Chinese manuscript: The Art of War, this eBook discusses DevOps in the form of a mission to continuously deliver assets to the operational battlegrounds safely, securely, and quickly.

VMware have been previewing a number of container based technologies recently, and for those already running a VMware stack this overview is likely very useful.

It’s often too easy for sensitive information to end up publicly accessible on GitHub, whether that’s git tokens, SSH private keys or AWS credentials. Gitrob is a tool aimed an internal security folk for finding that information before it can be used against you.

A nice description of the utility of the CoreOS toolbox, a pattern that’s applicable to any minimal OS/container combination. The idea that for debugging you can bring your own tools with you only when needed.

The Goat Farm is a relatively new podcast focused on Devops practices in large enterprise organisations. 9 episodes in and it has some great interviews with people from IBM, Standard Bank, Target and more. If you have stories to share get in touch with the presenters.

One of the talks from Operability this week, on common problems with logging and how to fix them. Some good points about why it’s important to log accurate and useful information too.

Another talk from Operability, this one by me entitled operations without the operating system. How does operations change as the OS becomes drastically simpler or disappears entirely?

Confidentiality, integrity and availability is a common way of talking about information security. This handy presentation maps those concepts to devops practices, likely a great way of building bridges between ops and security.

An impassioned plea to sell the business value of being able to deploy software early in a project. A good reminder that this isn’t a given everywhere.

Tools

Muxy looks like a pretty comprehensive tool for testing network activity, by introducing delays, bandwidth constraints or other issues. It works as a simple proxy with a configuration file to control the features.

Traefik looks an interesting new reverse proxy with some modern capabilities like integration with service management frameworks, hot reloading of configuration, exposing metrics over HTTP and an API for configuration.

At this point the AWS interface is huge, so SAWS might be a good alternative command line interface. In particular it provides command completion and shortcuts which should make things both quicker and more discoverable.
