How to Register a GitHub Actions Self-Hosted Runner on RHEL 9 — step-by-step RHEL 9 tutorial on Progressive Robot

How to Register a GitHub Actions Self-Hosted Runner on RHEL 9

GitHub Actions self-hosted runners allow running GitHub Actions CI/CD workflows on your own infrastructure instead of GitHub’s shared runners. This is essential when workflows need to: access private network resources (internal databases, Docker registries, Kubernetes clusters), use specialised hardware (GPUs, large memory), comply with data residency requirements, or reduce GitHub Actions billing costs for high-volume […]

How to Configure Jenkins Pipelines and Jenkinsfile on RHEL 9

Jenkins Pipeline (formerly Workflow) allows defining the entire CI/CD build, test, and deploy process as code in a Jenkinsfile committed to the source repository alongside the application code. This “Pipeline as Code” approach means the build process is version-controlled, reviewable via pull requests, and reproducible across environments. Jenkins supports two Pipeline syntaxes: Declarative Pipeline (structured, […]
