The Configuration as Code plugin and "id must be specified" errors

· jenkins · job-dsl · casc ·

Yesterday we rebuilt and re-deployed one of the Jenkins containers we use at work, and much to my chagrin the Jenkins environment no longer wanted to boot. We use Jenkins on top of Kubernetes, integrated with Hashicorp Vault, configured with the Configuration as Code plugin and the Job DSL plugin. While I am pleased with this stack of tools, it is not a “simple” set up. It had been three weeks since the last rebuild and redeploy, and the name of the game was: what of the dozen changes that have happened in one of these tools over the last three weeks was the culprit.


I hate the made up word 'performant'

· opinion ·

The tech industry is filled with all sorts of silly jargon and acronyms. Our overuse of jargon not only makes us very easy to identify in a crowded restaurant but also helps make things confusing for new-comers and veterans alike. In my current role, I find myself spending a lot of time with vendors who also seem to delight in barraging prospects with unpleasant jargon. My least favorite word among it all is performant.


Modeling continuous delivery

· otto · pipeline ·

I spend more time than I wish to admit thinking about how continuous delivery (CD) processes should be modeled. The problem domain is one that affects every single organization which distributes software, yet the approach each organization takes is almost as unique as the software they develop. From my perspective Jenkins Pipeline, especially its declarative syntax, is the best available option for most organizations to model their continuous delivery processes. That does not mean however that I believe Jenkins Pipeline is the best possible option.


545 miles in slow motion

· alc · cycling ·

San Francisco, Santa Cruz, King City, Paso Robles, Santa Maria, Lompoc, Ventura, Los Angeles. For the better part of seven days, I sat on a bicycle with over 2,200 cyclists and 650 volunteers riding from one part of California to another to raise money for HIV/AIDS services as part of AIDS/LifeCycle. In perspective, 545 miles is further than the distance from Boston to Washington D.C., further than Brussels to Berlin, further than Tokyo to Hiroshima. It is countless hills, steep descents, farm fields, supportive on-lookers, packets of chamois butter, potholes, water bottles, and sliced bananas. Based on this, my first year’s experience, it is also six inner tubes, one bike tire, and an entire bike frame long.



Austria capturing the far-right zeitgeist

· opinion ·

For a myriad of reasons the only video-news I consume tends to be German-language news out of Germany. Local or national American news is usually lower quality, setting aside the abhorrent monopolies, it always trends towards an insular world view, missing many major international events. One such event skirting under radar of American media has been the disintegration of the Austrian parliament after the deputy chancellor, a member of a far-right party, was caught on video soliciting bribes from a woman posing as a relative to a Russian oligarch.


Marching towards JRuby/Gradle 2.0

· jrubygradle · jruby · gradle ·

JRuby/Gradle is one of the few open source projects which I created that actually resonates with people. One that I find myself continuing to work on, despite not using it in my day-to-day work. JRuby/Gradle is a collection of Gradle plugins which make it easy to build, test, manage and package Ruby applications. By combining the portability of JRuby with Gradle’s excellent task and dependency management, JRuby/Gradle provides high quality build tooling for Ruby and Java developers alike. With my fellow maintainer, Schalk Crojné, I started working towards the 2.0 milestone.


How Jenkins usage statistics work

· jenkins · cdf ·

For years the Jenkins project has published anonymous usage statistics to stats.jenkins.io. Despite its warts, the system has ultimately proven useful for determining which plugins are most frequently installed, big coarse-grained changes in growth, and providing various marketing departments with the validation they so desperately crave. Like many of the tucked away corners of the Jenkins project, being an infrastructure maintainer affords me an understanding of how the system works, and sometimes doesn’t. As I promised to the CDF Technical Oversight Committee many weeks ago, in this post I will attempt to describe how this system works.


What's Uplink

· jenkins ·

Making changes safely to an application like Jenkins is incredibly tricky. Jenkins is distributed to hundreds of thousands of independently owned and operated servers and is used in a myriad of ways. Our changes with the best intentions, can still result in confounding bugs and errors for users with different configurations, or different combinations of plugins. Over on the Jenkins project blog, Daniel wrote about the first use of “telemetry” by Jenkins core, a project on which we collaborated. I ended up building the backend service for receiving this telemetry, Uplink, and I hope it paves the way for making smarter changes across Jenkins core in the future.


Oh shit. One month until AIDS/LifeCycle 2019!

· alc ·

Today marks one month until the beginning of AIDS/LifeCyle 2019 (ALC)! Which means I am one month away from starting a bicycle journey with thousands of other riders from San Francisco to Los Angeles as part of our effort to raise money for AIDS/HIV related services. As of this writing, my fundraising is at $3,377 which is still short of my fundraising goal: $5,000. If you appreciate my work in the Jenkins project, the JRuby/Gradle project, or if you have enjoyed my sass on Twitter, please convert your appreciation into a donation to AIDS/LifeCYcle. :)
