Jenkins is the way to robot ‘em all
Elastic Observability
Building unified visibility across entire ecosystems.
Background: Tasked with creating software that provides unified visibility across entire ecosystems, the technology division of an open-source community knew they needed to develop a common platform for all projects, including logs, metrics, and APM data. That, coupled with the need to support different operating systems, programming languages and architectures proved quite challenging for this team.
Goals: To standardize pipelines across all projects.

Ivan Fernandez, Software Engineer
Solution & Results: First, we created a system that provided the ability to grab log metrics and APM data from user applications and environments at runtime, store it in our search database, and provide the ability to analyze that data with Kibana and ML. By standardizing the pipeline, we created a shared library that allows us to reuse common code across all of our projects. What’s great about this is that other software teams are reusing this development for their projects as well.**
To tackle our second challenge – different architectures – we used Jenkins. Because it supports any architecture with Java 8 support, it was easy to add Linux/Windows Agents in Google Cloud, Mac Agents on MacStadium, and ARMv8 Agents. Now we can test on four architectures and more than 20 different OS versions and types, with more to come in the future. **
The key capabilities we relied on Jenkins for were:
-
Portability to different OS and architectures: this makes it simple to launch our test on those OS and platforms.
-
Reusability of common pipeline steps across projects: our pipeline shared library saves us time.
-
Extensibility on pipelines: we have an encapsulated process on pipeline steps, making it easier to use.
-
Pipeline definition as code: every project has its pipeline in its repo.
Jenkins rocks because now we just build and test it. No hands! Simply push to GitHub and everything is magic. We also liked the results that it provides:**
-
A common tool for executing builds, tests, and deploys
-
Support for different OS and architectures out-of-the box
-
Ability to scale up to 400 ephemeral Agents at the same time
-
Reporting with GitHub checks and GitHub comments
-
Trigger builds with GitHub Comments
