Kubernetes: The smart person’s guide

Kubernetes is a series of open source projects for automating the deployment, scaling, and management of containerized applications. Find out why the ecosystem matters, how to use it, and more.

First, Docker transformed how we ran applications. Then, Kubernetes changed how we managed containers. Now, the open-source project Istio is building on both to add a network service mesh.

Istio is built on the open-source Envoy proxy. This service mesh enables microservices sharing distributed applications to communicate and work with one another. As Matt Klein, Envoy’s creator wrote, Istio provides modern microservice and cloud-native applications with a “unified control plane that ties the pieces together in a coherent way.”

Istio also enables DevOps. In a soon-to-be-released blog, Google Cloud‘s Eric Brewer, VP Infrastructure, and Eyal Manor, VP of Engineering, point out that Istio provides vital DevOps framework “such as a common system for monitoring, logging, authorization, and billing.”

Brewer and Manor go on: “You need tools to manage the collection of microservices, and to ensure consistent policies across them. More importantly, these policies need to be decoupled from the individual services, so that they can be more uniform and updated independently of the services.”

Istio does this at the network level. By working over the network, Istio makes it easy to integrate microservices with load balancing, service-to-service authentication, monitoring, and more, with no changes to the underlying code.

Brewer and Manor continue: “Istio offers visibility in the form of telemetry for monitoring and logs for your services, plus security by giving each service a strong identity based on its role, as well as enabling encryption by default. With that core functionality place, Istio can also be the basis for higher-level services, e.g., helping to enforce network security policies, or controlling software rollouts through canary deployments.”

This, in turn, means, “Istio also ensures a proper decoupling between development and operations, allowing operations teams to change the behavior of the system without actually changing the source code.”

Thus, Brewer and Manor said this decoupling of development and operations logic that Istio provides accomplishes two things: It allows your developers to focus on writing business logic, not infrastructure (thus making them more productive), and it gives your operations teams the tools they need to run your applications and services more reliably.

Istio has already reached its 1.0 release. And, now it’s being deployed by such users as Descartes Labs, eBay, and AutoTrader UK. “Istio was a missing piece in the Kubernetes ecosystem. Kubernetes gave us the ability to distribute an application, but Istio gave us the ability to understand the application,” said Tim Kelton, a Descartes Labs co-founder, in a statement.

Google is pushing to bringing more users to Istio. Istio will be made available for Google Cloud users on Google Kubernetes Engine (GKE) in beta in December. On GKE, Istio layers a service mesh on your existing GKE clusters, and gathers telemetry on their containers. This data is then sent to Stackdriver or Prometheus. With these, you can monitor your Kubernetes-based microservices’ traffic, error rates, and latencies.

Google’s not the only company betting Istio is about to become important. IBM, Red Hat, and VMware are also working on improving the open-source network service mesh. It may well be that Istio may be an important part in IBM’s Red Hat post-acquisition hybrid-cloud plans.

How To Build Your Own Retro Gaming Console With A Raspberry Pi

Published

on

Once your micro SD card is mounted with RetroPie, you can plug it into your fully assembled Raspberry Pi 4 and begin the setup process in the software menu that appears. Make sure your controller is nearby, as you’ll need it during the first boot process. If you’re using a USB controller, make sure it’s connected physically, then follow the instructions on-screen.

If you’re using a Bluetooth controller, tap F4 on your USB keyboard to exit back into the Linux command prompt screen, then type and execute the command “sudo ~/RetroPie-S etup/retropie-setup.sh” that loads you into a backend RetroPie menu. Navigate to the Bluetooth option and then open it to begin searching for a controller. Set your Bluetooth controller to sync mode, then pair it in the menu. Return to the Linux command prompt and type the command “sudo shutdown -r now”. Upon loading back into RetroPie, you should be able to use your Bluetooth controller by simply turning it on and following the on-screen menu. Once everything is complete, you’ll end up on another menu with the option RASPI-CONFIG, which you should now select.

Upon tapping that option, you’ll be taken to the main configuration menu for RetroPie, which includes all sorts of different settings. Go ahead and configure whichever settings you need. It’s also a good idea to navigate to Advanced Settings and disable Overscan if you’re using an HDTV. From here, you should be able to load your ROMs (stored on your SD card) and play them from the menu that appears when you boot up RetroPie. Check out the RetroPie documentation for troubleshooting any issues you may encounter, and happy gaming!

Today’s Wordle Answer #377 – July 1, 2022 Word Solution And Hints

Published

on

The solution for the July 1, 2022, edition of Wordle is pinto. It made its way to the English vocabulary from the Spanish word pinto, which refers to a subject that is spotted or mottled. Horses with a patchy coloration, especially those rocking white patches, are affectionately known as pinto.

The word traces its etymological roots to the Latin term pinctus, which is used to describe something that has been painted over. The pinto bean, which is a staple in Mexican, Spanish, and Brazilian cuisines, also gets its name from the patchy color profile of its outer skin. According to Ancestry data, Pinto is a popular Catalan name that eventually made its way to the Indian subcontinent with the advent of Portuguese invaders.

Interestingly, it is also used to describe a person with greying hair, something pop culture describes as a salt-and-pepper look. You can trace the history of Pinto family migration across the U.S. and Canada in the 19th century here. As for famous personalities with that surname, the actress described above is Freida Pinto, while the footballer in question is José Manuel Pinto. Meanwhile, Fernão Mendes Pinto was a renowned Portuguese explorer and writer who also has a crater on the planet Mercury named after him.

This New $6 Raspberry Pi Is The Computer The DIY Smart Home Needs

Published

on

In terms of hardware, the Raspberry Pi Pico W is identical to its predecessor; it sports the same RP2040 Arm Cortex M0+ Dual-Core SoC, which is based on TSMC’s 40nm low power manufacturing process. This chip clocks up to 133MHz and also packs in 264KB of SRAM. There is 2MB of onboard flash storage thrown in, as well. Additionally, the machine features a 40-pin GPIO just like the original Pico from 2021. The onboard micro USB controller can be used for data transfer and receiving power.

The Wi-Fi module on the Raspberry Pi Pico is the Infineon CYW43439 wireless that, apart from supporting 2.4GHz Wi-Fi networks, also adds Bluetooth Classic and Bluetooth Low-Energy support. However, as of now, Raspberry has chosen not to enable Bluetooth capability in the machine. The company does not rule out the possibility of enabling Bluetooth further down the line, though.

With over 2 million Raspberry Pi Pico boards in the hands of consumers, the company expects its new model to enjoy similar success. The company also believes that the ongoing chip shortage has been among the prime reasons for the popularity of the RP2040-based Raspberry Pi Pico. The Pico W, thanks to its newfound wireless capability, will continue to be a great product that can power many IoT-based applications and DIY smart home needs. With a price tag of $6, the Raspberry Pi Pico W costs just $2 more than its predecessor. As the ecosystem for starter microcontrollers evolves, the $6 you spend on the Pico W will definitely be a worthwhile investment.
