  • 5 ops hacks for sysadmins

    As a sysadmin, every day I am faced with problems I need to solve quickly because there are users and managers who expect things to run smoothly. In a large environment like the one I manage, it's nearly impossible to know all of the systems and products from end to end, so I have to use creative techniques to find the source of the problems and (hopefully) come up with solutions.

    This has been my daily experience for well over 20 years, and I love it! Coming to work each day, I never quite know what will happen. So, I have a few quick and dirty tricks that I default to when a problem lands on my lap, but I don't know where to start.

  • Are you being the right person for DevOps?

    What does it mean to be the "right" person in a DevOps environment? That's the question that Josh Atwell, senior tech advocate at Splunk, tried to answer in his Lightning Talk at All Things Open 2019.

    "Being the right person for DevOps is being more than just your ops/dev role," says Josh. "In order to be the right person for DevOps, you have to be improving yourself, and you have to be working to improve for others."

    Watch Josh's Lightning Talk, "Are you being the right person for DevOps?" to learn why you should add communication, selflessness, self-care, and celebration to your list of core DevOps traits.

  • Infrastructure-as-Code mistakes and how to avoid them

    Two industry trends point to a gap in DevOps tooling chosen by many. Operations teams need more than an Infrastructure-as-Code approach, but a complete model-driven operations mentality. Learn how Canonical has addressed these concerns by developing Juju, an open source DevOps tool, to allow it create multiple world-leading products.

    [...]

    Juju is simple, secure devops tooling built to manage today’s complex applications wherever you run your software. Compute, storage, networking, service discovery and health monitoring come for free and work with Kubernetes, the cloud and the laptop.

    Juju allows your software infrastructure to maintain always-optimal configuration. As your deployment changes, every applications’ configuration operations are dynamically adjusted by charms. Charms are software packages that are run alongside your applications. They encode business rules for adapting to environmental changes.

    Using a model-driven mentality means raising the level of abstraction. Users of Juju quickly get used to a flexible, declarative syntax that is substrate-agnostic. Juju interacts with the infrastructure provider, but operations code remains the same across. Focusing on creating a software model of your product’s infrastructure increases productivity and reduces complexity.

    Automating infrastructure at a low level of abstraction, DevOps has bought the industry from breathing space. But that breathing space is running out.

  • 5 Kubernetes trends to watch in 2020

    “As more and more organizations continue to expand on their usage of containerized software, Kubernetes will increasingly become the de facto deployment and orchestration target moving forward,” says Josh Komoroske, senior DevOps engineer at StackRox.

    Indeed, some of the same or similar catalysts of Kubernetes interest to this point – containerization among them – are poised to continue in 2020. The shift to microservices architecture for certain applications is another example.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • 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.
