  • How to build, run, and manage container images with Podman | FOSS Linux

    Linux Containers have been around for some time but were introduced in the Linux kernel in 2008. Linux containers are lightweight, executable application components that combine app source code with OS libraries and dependencies required to run the code in different environments.

    Developers use containers as an application packaging and delivery technology. One key attribute of containers is combining lightweight application isolation with the flexibility of image-based deployment methods.

    RHEL based systems like CentOS and Fedora Linux implements containers using technologies such as control groups for resource management, namespaces for system process isolation, SELinux for security management. These technologies provide an environment to produce, run, manage and orchestrate containers. In addition to these tools, Red Hat offers command-line tools like podman and buildah for managing container images and pods.

    When developers and administrators have to configure multiple servers at a time with similar configurations then instead of repeating the same tasks on each system one by one they use special configuration managers such as Puppet. Ideally, many tasks can be automated with it using Puppet’s Domain-Specific Language (DSL) — Puppet code — which you can use with a wide array of devices and operating systems. It was developed in 2005 by Puppet Labs, Portland, Oregon; written in Ruby and designed to be cross-platform. Any login term enterprise operating system can be used to host Puppet servers such as OracleLinux, RedHat, SuSE, Ubuntu, Debian AlmaLinux, and Rocky Linux. Systems running Windows can also be configured and managed with Puppet, with some limitations.

  • How to Use GitLab’s Built-In Sentry Error Tracking Service – CloudSavvy IT

    Sentry is a popular error-tracking platform that gives you real-time visibility into issues in your production environments. GitLab’s Error Reporting feature lets you bring Sentry reports into your source control platform, offering a centralized view that unifies Sentry errors and GitLab issues.

    The feature originally relied on an integration with an existing Sentry service, either the official Sentry.io or your own self-hosted server. This changed with GitLab 14.4 which added a lightweight Sentry-compatible backend to GitLab itself. You no longer need an actual Sentry installation to get error reports into GitLab.

    Here’s how to get started with the integrated Sentry backend. Before we proceed, it’s worth mentioning that this capability might not be right for you if you’re already acquainted with the Sentry dashboard. GitLab’s backend is a barebones solution which surfaces errors as a simple list. It’s best for smaller applications where you don’t want the overhead of managing a separate Sentry project.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
