This article extends the discussion about passing data between nodes in Jenkins pipelines, focusing on a key mechanism: stash and unstash. While stash is commonly used in distributed pipelines, many…
Jenkins pipelines allow users to execute Groovy code to automate builds, deployments, and infrastructure operations. Because this code may come from repositories or contributors who do not have administrative access…
Introduction As CI/CD pipelines grow alongside modern microservice architectures, Jenkins pipelines often become increasingly complex. What starts as a simple Jenkinsfile quickly evolves into a large script containing build logic,…
This document explains how to structure and use modular Jenkins pipelines using external Groovy include files.The goal of this approach is to improve pipeline readability, maintainability, and reuse by separating…
Overview During a migration of our internal Jenkins controller from HTTP to HTTPS/TLS, several Jenkins pipelines running on Kubernetes agents began failing. These pipelines use dynamically provisioned agents created by…
In a modern DevOps infrastructure, operating an internal Public Key Infrastructure (PKI) is essential to secure communications between services. Instead of relying on self-signed certificates or external certificate authorities, organizations…
Deploying an internal certificate authority is only the first step in building a secure infrastructure.Once certificates start being issued, every system that communicates with services signed by the CA must…
In the previous sections we demonstrated how Kubernetes services can obtain certificates automatically using cert-manager and ACME, or manually using the Step CLI. However, many infrastructure services still run outside…
As CI/CD pipelines grow, Jenkins jobs tend to produce a large number of builds. When multiple branches, environments, and versions are involved, the default Jenkins build numbering quickly becomes difficult…
In many CI/CD workflows, pipelines need to adapt based on dynamic infrastructure data. For example: Hardcoding these options inside Jenkins parameters quickly becomes unmaintainable. A much better approach is using…
