The Open Organization Guide to IT Culture Change

The open organization community at Opensource.com (of which I’m a member) is pleased to announce the immediate release of its newest book, The Open Organization Guide to IT Culture Change. As IT teams around the world rise to these new challenges, they’re realizing that radical change isn’t a matter of tools alone. It’s also a matter of culture—the values that underpin behaviors, influence problem-solving capability, and facilitate truly revolutionary potential. Those values are open values. [Read More]

A Night of DevOps at Open Source South Carolina

On Tuesday, May 23, 2017, I did a DevOps talk at Open Source South Carolina. The talk was a DevOps 101-styled deep dive into DevOps. Since the number one question I get when talking about DevOps, in general, is “where do I start?” I added my “The Three Things” to the already well known “Three Ways”. This provided both the holistic view while guiding people needed an extra nudge down the DevOps path. [Read More]

"Good SysAdmin to DevOps Engineer in Six Months"

The other day my Vice President asked me a question, “What would it take to turn a good SysAdmin into a DevOps engineer?” He followed it up with, “Don’t spend more than ten minutes thinking about it.” He was not disappointed when I told him the next day I am spending way more than ten minutes on answering the question. This is a hard question for me to answer. This is a question that you won’t know if your answer is right for at least six months. [Read More]

The Dark Side of DevOps

Disclaimer: These are real world experiences I have had within organizations that I have been employed by. Identifying information is intentionally anonymous. If you read this and think you are one of the teammates please keep that to yourself for the sake of others. A lot of people think that DevOps, Cloud Native, Agile, GROWS, etc. are all rainbows and roses. You start small and work your way up to full blown operations or you decide as an organizational unit to change. [Read More]

Recent Accomplishments

I feel like I should say I don’t like to toot my own horn. But, if I don’t toot it who will? December and January were very busy months for me and February is definitely going to be busy. You should always be working outside your personal and professional comfort zones. Last month, a DZone editor reached out to me asking to write a piece for the DZone DevOps: Continuous Delivery and Automation guide. [Read More]

Find EC2 Instances That Are Missing Tags

The team here was trying to align AWS resources for billing by using Tags. Seems easy enough but we were having issues trying to figure out which EC2 instances were not tagged. We also wanted to find EC2 instances that are missing a ROLE tag. We searched high and low and found that several people needed a solution. We tried to cobble something together with the AWS CLI and then Ansible. [Read More]

GitLab Annoyance: Private to Public Repos

I was working on a new Ansible role last week and was having problems with Test Kitchen. The issue I was having was that Test Kitchen was unable to pull in dependencies from GitLab for the Ansible role I was developing. Here is the error message I was seeing: [WARNING]: - rsyslog was NOT installed successfully: - command git clone https://gitlab.logicnow.com/ansible-roles/rsyslog.git rsyslog failed in directory /tmp/tmpEaRVAA (rc=128) I realized that on our internal, private GitLab server a repo needed to be changed from Private to Public.

Military Lessons Applied to DevOps: Operation Eagle Claw

As part of preparing for my talk at DevOpsDays Detroit, I did a significant amount of research into military failures. It was hard to find a military failure that did not evoke an emotional response or political discussion. But, I was prepared to talk about two: The 1961 Goldsboro B-52 Crash and the failed Iran hostage rescue, Operation Eagle Claw. In the case of Operation Eagle Claw, you can draw a comparison to the old IT silo mentality of Dev and Ops being two different teams with very different objectives. [Read More]

Triangle DevOps: What The Military Taught Me About DevOps

I had the opportunity to present What The Military Taught Me About DevOps at the Triangle DevOps Meetup last night. It was a fantastic group of people and I fielded a lot of great feedback after speaking. One person asked if I would be willing to share my slides. I informed him that they were already shared but I think the notes that accompany the slides are important to share too: [Read More]
