  • Building Images with Dockerfile and Docker Hub

    In this series previewing the self-paced Containers for Developers and Quality Assurance (LFS254) training course from The Linux Foundation, we’ve covered installing Docker, introduced Docker Machine, and some basic commands for performing Docker container and image operations. In the three sample videos below, we’ll take a look at Dockerfiles and Docker Hub.

    Docker can build an image by reading the build instructions from a file that’s generally referred to as Dockerfile. So, first, check your connectivity with the “dockerhost” and then create a folder called nginx. In that folder, we have created a file called dockerfile and in the dockerfile, we have used different instructions, like FROM, RUN, EXPOSE, and CMD.

  • What can developers learn from being on call?

    We often talk about being on call as being a bad thing. For example, the night before I wrote this my phone woke me up in the middle of the night because something went wrong on a computer. That’s no fun! I was grumpy.

    In this post, though, we’re going to talk about what you can learn from being on call and how it can make you a better software engineer!. And to learn from being on call you don’t necessarily need to get woken up in the middle of the night. By “being on call”, here, I mean “being responsible for your code when it breaks”. It could mean waking up to issues that happened overnight and needing to fix them during your workday!

  • Making the Internet Archive’s full text search faster.

    The Internet Archive is a nonprofit digital library based in San Francisco. It provides free public access to collections of digitized materials, including websites, books, documents, papers, newspapers, music, video and software.

    This article describes how we made the full-text organic search faster — without scaling horizontally — allowing our users to search in just a few seconds across our collection of 35 million documents containing books, magazine, newspapers, scientific papers, patents and much more.

  • DevOps: More Than Automation

    Type “devops” into any job search site today and the overwhelming majority of results will be for some variation of “DevOps Engineer”. The skills required will centre on tools like Puppet/Chef/Ansible, AWS/Azure, scripting in Python/Perl/Bash/PowerShell etc. Essentially, they’ve taken a deployment automation engineer role, crossed out “deployment automation” and written “DevOps” in its place.

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.
