How to Configure Suricata IDS/IPS on RHEL 7 Suricata is a high-performance, open-source network threat detection engine maintained by the Open Information Security Foundation (OISF). It can operate as an Intrusion Detection System (IDS), passively monitoring traffic and alerting on suspicious patterns, or as an Intrusion Prevention System (IPS), actively blocking malicious connections using the […]
How to Use Skaffold for Kubernetes Development on RHEL 7 One of the most tedious aspects of Kubernetes development is the inner loop: make a code change, build a container image, push it to a registry, update the Kubernetes manifest, apply it to the cluster, and wait for the rolling update — repeated dozens of […]
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 Set Up a Local Container Registry with Harbor on RHEL 7 Harbor is a CNCF-graduated open-source container registry that extends a plain Docker registry with enterprise features: role-based access control (RBAC), replication policies, vulnerability scanning, content trust, and a web-based management UI. Running Harbor on your own RHEL 7 infrastructure means your container […]
How to Install and Configure Drone CI on RHEL 7 Drone CI is a lightweight, container-native continuous integration platform built around the concept of pipelines-as-code. Unlike Jenkins, which requires significant plugin management and XML configuration, Drone uses a simple YAML file (.drone.yml) stored in your repository to define every aspect of a pipeline. Drone’s server […]
How to Install Packer for Machine Image Automation on RHEL 7 Packer, developed by HashiCorp, is an open-source tool that enables you to create identical machine images for multiple platforms from a single source configuration. Whether you are building AMIs for AWS, OVA files for VMware, or disk images for on-premises hypervisors, Packer automates the […]
How to Set Up Vagrant and VirtualBox on RHEL 7 Vagrant is an open-source tool by HashiCorp that automates the creation, configuration, and management of virtualized development environments. Combined with VirtualBox as a hypervisor backend, Vagrant allows developers and operations engineers on RHEL 7 to spin up reproducible Linux (or Windows) virtual machines with a […]
How to Install and Use Helm for Kubernetes Package Management on RHEL 7 Helm is the de facto package manager for Kubernetes, often described as the “apt” or “yum” of the container orchestration world. Rather than maintaining dozens of raw YAML manifests for every application you deploy, Helm bundles them into versioned, reusable packages called […]
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, […]
