  • Unprivileged container builds using stacker

    One of the primary goals of user namespaces was to provide the ability for unprivileged users to have their own range of uids over which they would have privilege, with minimal need for setuid programs and no risk (barring bugs in the OS) of their privilege having effect on uids which are not “their own”.

    We’ve had user namespaces for awhile now. While there are some actions which cannot be done in a user namespace, such as mounting a loopback filesystem, there are many things, such as setting up a build environment with custom package installs, which used to be a challenge without privilege but are now simple.

  • Red Hat eyes cloud-native Java future with Quarkus

    Red Hat's latest initiative, Quarkus, aims to usher in a cloud-native Java future -- and shift the core of innovation in enterprise Java.

    Numerous efforts over the years have attempted to make Java more cloud-native, such as Google's Dalvik virtual machine used in Android. None has demonstrated as much promise as Red Hat Quarkus, which is based on two Oracle-led projects, GraalVM and Substrate VM, to build cloud-native Java applications that are much faster and smaller, in a Linux container as part of a Kubernetes deployment.

    GraalVM is a universal virtual machine that is used to run applications written in JavaScript, Python, Ruby, R, and Java Virtual Machine (JVM) based languages, including Java, Scala, Clojure, Kotlin, as well as low-level virtual machine-based languages, such as C and C++. Graal enables aggressive ahead-of time (AOT) compilation, so developers can compile their apps into native binary images and avoid the limitations of the JVM.

    Substrate VM, a subsystem of Graal, focuses on AOT compilation to collect Java to a native binary image, said Mark Little, vice president of engineering and CTO of JBoss Middleware at Red Hat.

  • OpenShift All-in-One (AIO) for Labs and Fun

    A common request from customers is how to run the actual Red Hat OpenShift Container Platform (OCP) bits in a single node. This request often comes from customers that need to support training environments, dedicated single-user development environments or from technical architects wanting to validate concepts without deploying a full multi-node cluster. There are many options available for developers, from Minishift to CodeReady Workspaces. These are supported options which are a great solution for application developers that want to deploy to the platform. The use cases not addressed with these solutions are more platform and infrastructure related.

  • 7 pieces of contrarian Kubernetes advice

    You can find many great resources for getting smarter about Kubernetes out there. (Ahem, we’ve written a few ourselves.)

    That’s good news for IT teams and professionals looking to boost their knowledge and consider how Kubernetes might solve problems in their organization. The excited chatter about Kubernetes has gotten so loud, however, that it can become difficult to make sense of it all. Moreover, it can be challenging to sort the actual business and technical benefits from the sales pitches.

  • SwiftStack Announces World’s First Multi-Cloud AI/ML Data Management Solution

    “The SwiftStack solution accelerates data pipelines, eliminates storage silos, and enables multi-cloud workflows, thus delivering faster business outcomes,” said Jason Blum, CTO at GPL Technologies, an NVIDIA and SwiftStack elite partner. “SwiftStack provides us with the flexibility, technology leadership and breakthrough economics to build tailored solutions for our customers.” GPL Technologies has created multiple ways to implement the solution, with NVIDIA DGX-1 GPU server(s), NVIDIA GPU Cloud, and other leading system hardware.

  • Tetrate Aims To Make Service Mesh Accessible And Enterprise Ready

    After Kubernetes, open source projects such as Istio, Envoy and Linkerd get the maximum attention from the users and cloud native community. Google backs Istio while Envoy and Linkerd are a part of the Cloud Native Computing Foundation (CNCF). Since the current service mesh technologies are available only as stock open source projects, implementing and integrating them with the rest of the microservices infrastructure is complex.

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.
