This is a step-by-step guide to enable correlation between metrics and traces, using Prometheus, Grafana, Tempo, OpenTelemetry, and OpenMetrics. — Exemplars are coming! But what are exemplars? A few highlighted values in a time series, with a set of key-value pairs (labels). The main use-case is to include the request’s trace ID in the labels so that we can jump from a metric time series to the interesting traces directly…

Design and implementation of Cloud-Native CI/CD Pipelines on Kubernetes for the enterprise, using Jenkins X. — The cloud-native era has opened up a whole new level for CI/CD, and it’s impacting the design of our pipelines. The days of the big monolith pipeline that only one person can decipher are gone. …

Dailymotion’s journey from Jenkins to Jenkins X — One year ago, we wrote about our journey from Jenkins to Jenkins X. It’s time to take a step back and see where we are now and how this journey has impacted the way we write and deliver software at Dailymotion. We’ve been using Jenkins X for more than one…

In this blog post, we’ll see how easy it is to “protect” a web app behind Okta, using Nginx as a reverse-proxy in front of it. In a Kubernetes environment. — Our use-case We’re using both Kubernetes to deploy our applications and Okta as a company SSO. We’re also big fans of Jenkins X. Jenkins X comes with a few UI, which unfortunately don’t have native authentication/authorization implementation yet:

This is the fourth part of a series of blog posts on the internals of the Jenkins X Pipelines. We’ll focus on the “steps” that compose a pipeline, and we’ll see how they are implemented using Tekton. — In the previous part of this series, we’ve walked through the internals of the stages that compose a pipeline. Now we’ll see how the Jenkins X Steps — that compose a stage — are implemented. First, a few pointers:

This is the third part of a series of blog posts on the internals of the Jenkins X Pipelines. We’ll focus on the “stages” that compose a pipeline, and we’ll see how they are implemented using Tekton. — In the first part of this series, we’ve walked through everything that happened in the cluster, from the incoming GitHub WebHook event to a running Tekton pipeline. In the second part, we’ve talked about the “Meta Pipeline”, which is responsible for converting your Jenkins X Pipeline into a Tekton Pipeline…

This is the second part of a series of blog posts on the internals of the Jenkins X Pipelines. We’ll dive into the “Meta Pipeline”: the part of the workflow which is responsible for retrieving the right pipeline to execute, and to translate it into a format that Tekton can understand. — In the first part of this series, we’ve walked through everything that happened in the cluster, from the incoming GitHub WebHook event to a running Tekton pipeline. But pipelines can be complex, and built from multiple levels of inheritance. This is the case with the Jenkins X Pipelines, which supports…

This is a series of blog posts on the internals of the Jenkins X Pipelines, implemented using Prow and Tekton. — As I am starting to migrate from the Jenkins Declarative Pipelines to the (new) Jenkins X Pipelines — defined in YAML format and implemented using Prow and Tekton — I am diving into the internals of the system, because I like to understand how things works. So I am now…
