How to Configure Infrastructure as Code with Pulumi on RHEL 7 Infrastructure as Code (IaC) transforms manual cloud provisioning into version-controlled, repeatable programs. While tools like Terraform use a domain-specific language, Pulumi takes a different approach: you write infrastructure definitions in real general-purpose languages — Python, TypeScript, Go, or C# — giving you the full […]
How to Configure Prometheus AlertManager on RHEL 7 Prometheus collects and stores metrics, but on its own it cannot notify your team when something goes wrong. Alertmanager is the dedicated component that handles alert routing, deduplication, grouping, and delivery to receivers such as email, Slack, or PagerDuty. On RHEL 7, setting up Alertmanager alongside Prometheus […]

How to Install and Configure SonarQube on RHEL 7 SonarQube is an open-source platform for continuous code quality inspection and static analysis. It detects bugs, vulnerabilities, code smells, and security hotspots across dozens of programming languages, integrating naturally into CI/CD pipelines to enforce quality gates before code reaches production. On RHEL 7, setting up SonarQube […]
How to Set Up ArgoCD for GitOps on RHEL 7 GitOps is an operational model in which the desired state of your infrastructure and applications is stored declaratively in a Git repository, and an automated agent continuously reconciles that desired state with the actual running state in your Kubernetes cluster. ArgoCD is the leading open-source […]
How to Register a GitHub Actions Self-Hosted Runner on RHEL 7 GitHub Actions is a CI/CD platform built directly into GitHub, and while GitHub provides hosted runners for common workflows, there are many scenarios where you need to run workflows on your own infrastructure: accessing internal services not exposed to the internet, using specific hardware […]
How to Use Terraform to Provision Infrastructure on RHEL 7 Once Terraform is installed, the real power comes from writing complete, production-grade infrastructure configurations. A single Terraform project can define an entire cloud environment — VPC networking, subnets, security groups, EC2 instances, load balancers, and databases — all in version-controlled code that can be reviewed, […]
