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 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. :)

Thoughts about a secure enclave for Jenkins Pipeline

· jenkins · pipeline · opinion · otto ·

Continuous integration and continuous delivery (CI/CD) projects might just be one of the hardest to lock down and secure. As system designers and implementors we must enable developers to automate their builds, tests, and deployments. And yet, in doing so, we also give those same developers the ability to bypass many of the boundaries we may have set up to secure our environments. If you give me the ability to automate my deployment with a script, I can think of a number of ways in which that ability can lead to information disclosure or other types of breaches. Jenkins Pipeline is filled with any number of problematic examples here the same feature can be looked at as empowering or as compromising. I believe the immense flexibility of Jenkins Pipeline also gives us a path to provide automation which is inherently more secure than some competitors. In this post, I’ll outline one such idea: a pipeline secure enclave.

Using custom root certificates with Minikube

· kubernetes · scribd · minikube ·

If you were to draw a coordinate system for software, where the x-axis was “important to use” and the y-axis was “enjoyable to use”, x509 certificates would be at the extreme edge of the bottom right of quadrant four. Much as I dislike them, they are absolutely critical to securing practically everything we do. As is the case with most companies, Scribd uses custom root certificates to establish a controlled chain of trust for internal resources. A sensible practice, but can be a great learning exercise, causing you to discover all the various ways in which trust is defined and managed in a modern development environment.
