ArgoCD implements the GitOps pattern for Kubernetes by continuously reconciling the live state of your cluster with manifests stored in a Git repository. Running on RHEL 8, you interact with ArgoCD through its CLI, its web UI, or both, while a controller inside the cluster watches for drift and can automatically correct it. This tutorial […]
Helm is the de facto package manager for Kubernetes, allowing you to define, install, and upgrade complex applications using reusable chart packages. On RHEL 8, Helm integrates cleanly with an existing kubectl configuration, making it straightforward to deploy and manage workloads across your cluster. This tutorial walks you through installing Helm, working with chart repositories, […]
GitHub Actions self-hosted runners allow you to execute CI/CD workflows on your own hardware, giving you full control over the operating system, installed tooling, network access, and resource allocation. On RHEL 8 this is especially valuable for pipelines that must access internal systems, use licensed software, or run workloads that exceed GitHub’s hosted-runner resource limits. […]
With Terraform installed on RHEL 8, the next step is writing real-world HCL configurations that provision cloud infrastructure. HashiCorp Configuration Language 2 (HCL2) provides a clean, human-readable syntax for defining providers, resources, variables, and outputs that can be version-controlled alongside your application code. This tutorial walks through provisioning an AWS EC2 instance — covering input […]
Terraform by HashiCorp is the industry-standard tool for provisioning and managing infrastructure as code (IaC) across cloud providers, on-premises platforms, and SaaS APIs.

This tutorial walks through adding the HashiCorp […]
Once you have Ansible installed and your inventory configured, playbooks are the primary way to describe and enforce the desired state of your infrastructure. A playbook is a YAML file that groups one or more plays, each targeting a set of hosts and executing an ordered list of tasks. This tutorial covers playbook anatomy, the […]
Ansible is the leading open-source automation engine for configuration management, application deployment, and orchestration. On RHEL 8, you can install Ansible from the Extra Packages for Enterprise Linux (EPEL) repository or directly via pip3, giving you flexibility depending on your environment. This tutorial walks through both installation methods, basic inventory configuration, and running your first […]
Gitea is a lightweight, self-hosted Git service written in Go that provides a GitHub-like web interface with a tiny resource footprint — ideal for teams that want a simple hosted Git server without the overhead of a full GitLab installation. On RHEL 8, Gitea can be set up in under an hour using a single […]
GitLab CI/CD is built directly into the GitLab platform, making it straightforward to automate builds, tests, and deployments without installing a separate CI server. Pipelines are defined in a .gitlab-ci.yml file committed to your repository, and they execute on GitLab Runners — lightweight agents that can run on bare metal, virtual machines, or inside Docker […]
GitLab Community Edition is a full-featured, self-hosted DevOps platform combining Git repository management, issue tracking, CI/CD pipelines, and a container registry in a single application.
