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. Running GitLab CE on RHEL 8 gives you complete control over your source code and pipeline infrastructure without relying on third-party SaaS providers. This tutorial covers installing GitLab CE from […]
Jenkins Pipelines allow you to define your entire build, test, and deployment workflow as code stored alongside your application. On RHEL 8 with Jenkins already installed, the Declarative Pipeline syntax offers a structured, human-readable format that is easy to maintain and review. This tutorial covers creating a Pipeline job in the Jenkins UI, writing a […]
Jenkins is the most widely used open-source automation server for building, testing, and deploying software. On Red Hat Enterprise Linux 8, setting up Jenkins provides a stable CI foundation backed by enterprise-grade OS support. This tutorial walks through installing Jenkins on RHEL 8 using the official package repository, configuring the firewall, and completing the initial […]
The Kubernetes Dashboard is a web-based UI that gives cluster operators a visual overview of workloads, services, namespaces, and resource utilization without dropping into kubectl for every task. On RHEL 8 with a running Kubernetes cluster, deploying the dashboard takes only a few kubectl commands. This tutorial covers installation, creating a service account with the […]
By default, the Docker daemon socket at /var/run/docker.sock is accessible only on the local host, but when you need to manage containers remotely — from a CI system, a monitoring server, or a developer workstation — you must expose the Docker API over TCP. Without TLS, any client with network access can control your Docker […]
Skopeo is a command-line tool for working with container images and registries without requiring a running container daemon. On RHEL 8 it is available directly from the default repositories, making it one of the easiest container tools to install and use. Unlike Docker CLI, Skopeo can inspect, copy, sync, and delete images across registries without […]
Secrets management is one of the most commonly mishandled aspects of containerized applications. Embedding passwords, API keys, or tokens directly in a Dockerfile or committing them to a repository exposes credentials to anyone who can read the image history or the source tree. RHEL 8 gives you several layers of defense: environment variable files, Docker […]
Multi-stage builds are one of the most powerful features in Docker, allowing you to produce lean production images by separating the build environment from the runtime environment. On RHEL 8, where production image size and attack surface matter, multi-stage builds reduce final image size dramatically by discarding build tools and intermediate artifacts. This tutorial walks […]
