Test de Podman Compose

Lors du test de Podman Compose, nous avons constaté que les fonctionnalités sont limitées par rapport à Docker Compose. Nous avons également constaté que l’utilisation de fichiers YAML Kubernetes est recommandée pour ce type de tâches. Nous avons également constaté que le Podman team peut corriger les problèmes rencontrés avec Podman Compose. Enfin, nous avons constaté que Docker Compose peut être utilisé en combinaison avec Podman.

Conclusion

En conclusion, Podman Compose est une bonne solution pour les utilisateurs qui souhaitent utiliser des fichiers Compose selon la spécification Compose avec un backend Podman. Cependant, il est important de garder à l’esprit que les fonctionnalités sont limitées par rapport à Docker Compose et que l’utilisation de fichiers YAML Kubernetes est recommandée. Il est également possible d’utiliser Docker Compose en combinaison avec Podman. Enfin, le Podman team peut corriger les problèmes rencontrés avec Podman Compose.

The Evolution of Configuration Management: IaC vs. GitOps

,

Misconfigurations are the leading cause behind security incidents in Kubernetes-orchestrated or otherwise containerized environments. Without proper configuration in place, applications would run into problems ranging from noncompliance and inconsistencies to performance bottlenecks, security vulnerabilities, and functionality failure. Therefore, configuration management is a critical component in a software development lifecycle for maintaining systems in a desired, consistent state.

According to Red Hat’s State of Kubernetes Security report, misconfigurations were the leading cause behind security incidents in Kubernetes-orchestrated or otherwise containerized environments. Without proper configuration in place, applications would run into problems ranging from noncompliance and inconsistencies to performance bottlenecks, security vulnerabilities, and functionality failure. This would make cloud-native systems unstable and cause them to become a liability to businesses. For this reason, configuration management is a critical component in a software development lifecycle for maintaining systems in a desired, consistent state. However, the way configuration management is done has been evolving over the years. This post traces the history of configuration management, focusing on how GitOps handles this critical aspect of running cloud-native applications today.

Red Hat Summit 2022 – Talking Architecture Shop Series

, ,

It’s that time of year again when we get the Red Hat Summit 2022 call for papers!

This year seemed to be a perfect time to go all in with sessions around our architectures based on a series of talks we’ve designed to showcase the various aspects we cover. Some are vertical aligned and others are just customer domains, but all of them include extensive research into how to implement successful architectures at scale.

Three easy ways to run Kafka without Zookeeper

,

There has been a couple of years since the announcement of the removal of Apache Zookeeper as a dependency to manage Apache Kafka metadata. Since version 2.8, we now can run a Kafka cluster without Zookeeper. This article will go over three easy ways to get started with a single node cluster using containers.

Control and data planes

Apache Kafka implements independent control and data planes for its clusters. The control plane manages the cluster, keeps track of what brokers are alive, and takes action when the set changes. Meanwhile, the data plane consists of the features required to handle producers and consumers and their records. In the previous iterations, Zookeeper was the cluster component that held most of the implementation of the control plane.

Deploying an Apache Kafka mock service with Microcks

,

Developers are working with new applications every day using Apache Kafka as the backbone to implement an event-driven architecture (EDA) to support distributed systems. However, this adds new challenges when sharing across teams, even within the same organization. What endpoints are available? What is the structure of the message? That’s why payload examples became critical to speed up development. For this reason, having a reliable and enterprise-grade service to mock Apache Kafka should be an item in your EDA checklist. This post will do a quick review of the Microcks General Availability (GA) version and their support to Kafka.

What is Microcks?

17 Open Source Fonts You’ll Actually Love

,

The right typeface can make or break your website. As designers, we will always be naturally drawn towards the premium fonts such as Circular, DIN, or Maison Neue; Before you know it, your website is racking up a font bill larger than your hosting bill.

We’ve put together a list of open-source fonts that will rival your fancy fonts, and might even persuade you to switch them out. All the fonts listed here are completely open-source, which means they’re free to use on both personal and commercial projects.

Manrope

Manrope has sprung onto the font circuit in style, with a website better than most early startups. It’s a variable font, which means you have a flexible range of font weights to choose from in a single font file. Manrope is a personal favorite of mine, it has every ligature you could want, and is fully multi-lingual. It’s a lovely bit of everything as it states on the website: it is semi-condensed, semi-rounded, semi-geometric, semi-din, semi-grotesque.

Gidole

DIN – the font we all love, the font that looks great at every size, and the font that costs quite a bit, especially with a large amount of traffic. Gidole is here to save the day, it’s an open-source version of our favorite – DIN. It’s extremely close to DIN, but designers with a keen eye will spot very few minor differences. Overall, if you’re looking to use DIN, try Gidole out before going live. (There is also a very passionate community around the font on Github)

Inter

Inter is now extremely popular, but we wanted to include it as it’s become a staple in the open-source font world — excellent releases, constant updates, and great communication. If you’re looking for something a bit fancier than Helvetica and something more stable than San Francisco, then Inter is a great choice. The font has now even landed on Google Fonts, making it even easier to install. As of today: 2500+ Glyphs, Multilingual, 18 Styles, and 33 Features… do we need to say more?

Overpass

Overpass was created by Delvefonts and sponsored by Redhat, it was designed to be an alternative to the popular fonts Interstate and Highway Gothic. It’s recently cropped up on large ecommerce sites and is growing in popularity due to its large style set and ligature library. Did we mention it also has a monospace version? Overpass is available via Google Fonts, KeyCDN, and Font Library.

Public Sans

Public Sans is a project of the United States Government, it’s used widely on their own department websites and is part of their design system. The font is based on the popular open-source font Libre Franklin. Public Sans has great qualities such as multilingual support, a wide range of weights, and tabular figures. The font is also available in variable format but this is currently in the experimental phase of development.

Space Grotesk

Space Grotesk isn’t widely known yet, but this quirky font should be at the forefront of your mind if you’re looking for something “less boring” than good old Helvetica. Space Grotesk has all the goodies you can expect from a commercial font such as multiple stylistic sets, tabular figures, accented characters, and multilingual support.

Alice

Alice is a quirky serif font usually described as eclectic and quaint, old-fashioned — perfect if you’re looking to build a website that needs a bit of sophistication. Unfortunately, it only has one weight, but it is available on Google Fonts.

Urbanist

Urbanist is an open-source variable, geometric sans serif inspired by Modernist typography. Designed from elementary shapes, Urbanist carries intentional neutrality that grants its versatility across a variety of print and digital mediums. If you’re looking to replace the premium Sofia font, then Urbanist is your best bet.

Evolventa

Evolventa is a Cyrillic extension of the open-source URW Gothic L font family. It has a familiar geometric sans-serif design and includes four faces. Evolventa is a small font family, generally used across the web for headlines and bold titles.

Fira Sans

Fira Sans is a huge open source project, brought to you, and opened sourced by the same team that makes Firefox. It’s Firefox’s default browser font and the font they use on their website. The font is optimized for legibility on screens. (And it’s on Google Fonts!)

Hack

Building a development website, or need a great code font to style those pesky code-blocks? Then Hack is the font for you. Super lightweight and numerous symbols and ligatures. The whole font was designed for source code and even has a handy Windows installer.

IBM Plex

IBM needs no introduction. Plex is IBM’s default website font and is widely used around the web in its numerous formats Mono, Sans, Serif, Sans-Serif, and Condensed – it has everything you’d need from a full font-family. The whole font family is multi-lingual, perfect for multi-national website designs. (It’s fully open-source!)

Monoid

Another great coding font, Monoid is a favorite of mine for anything code. The clever thing about Monoid is that it has font-awesome built into it, which they call Monoisome. This means when writing code, you can pop a few icons in there easily. Monoid looks just as great when you’re after highly readable website body text.

Object Sans

Object Sans (formally known as Objectivity) is a beautiful geometric font family that can be used in place of quite a few premium fonts out there. The font brings together the top qualities of both Swiss neo-grotesks and geometric fonts. The font works beautifully as large headings but can be used for body content as well.

Lunchtype

Lunchtype has a very interesting back-story, originally designed during the creator’s daily lunchtime during a 100-day project. If you’re looking for something a bit “jazzier” than the typical Helvetica for your project, then Lunchtype is a perfect choice. The family comes with numerous weights as well as a condensed version — enough to fill any lunchbox.

Jost

Inspired by the early 1920’s German sans-serif’s, Jost is a firm favorite in the open-source font world. Jost brings a twist to its closest web designer favorite Futura. When you want a change from the typical Futura, then Jost is a great option with its variable weighting as well as multilingual support.

Work Sans

Work Sans is a beautiful grotesk sans with numerous little eccentricities that may delight or annoy some designers. The font has variable weighting, multilingual support and is optimized for on-screen text use but works perfectly well for print also.

Building a Mission-Critical Open Source Java Platform – Installing WildFly

,

In the previous article in this series introduced our thoughts on setting up a mission-critical open source Java platform using high availability in our Web layer. In this article we’ll continue by installing WildFly and configure our platforms topology.

Note: the terminology in this article, where possible, has been adjusted from the traditional master / slave descriptions to master / subordinate. Some of the images displayed have not yet been updated and show the older terminology.

Building a Mission-Critical Open Source Java Platform – The Web Layer

,

Currently the Java platform is one of the most consolidated in the world, much of this is due to platform’s ability to support other languages such as Kotlin, Groovy and Scala, etc. Thousands of web and mobile applications are developed using the platform as a base. The Java platform has changed a lot in recent years and probably will keep evolving.

In parallel with these changes, we see the evolution application servers, that increasingly offer highly complex features such as load balancing components, smart asynchronous messaging, transaction control and many other technologies facilitating application development and standardization. They also provide a stable and scalable infrastructure for mission critical applications. One of the biggest challenges for application servers is to couple highly complex services, making them stable and flexible.
