Kubernetes 1.16 available from Canonical

Ubuntu

Canonical announces full enterprise support for Kubernetes 1.16, with support covering Charmed Kubernetes, MicroK8s and kubeadm.

MicroK8s will be updated with Kubernetes 1.16 enabling users access to the latest upstream release with a single-line command in under 60 seconds. In addition, MicroK8s gets new add-ons with one line installs of Helm and Cilium as well as enhancements, upgrades and bug fixes. Cilium adds enhanced networking features including Kubernetes Network Policy support. With MicroK8s 1.16, users can develop and deploy enterprise grade Kubernetes on any Linux desktop, server or VM across 42 Linux distros.

Canonical’s Charmed Kubernetes 1.16 will come with exciting changes like support for Kata Containers, AWS IAM, SSL passthrough and more. Using Kata Containers, insecure or untrusted pods can be run safely in isolation without disrupting trusted pods in deployments. Identity Access Management on AWS can be used to login to your Charmed Kubernetes cluster. Users get more control over their deployments while benefitting from reduced complexity due to improved LXD support and enhanced Prometheus and OpenStack integration.

“At Canonical, we enable enterprises by reducing the complexity of their Kubernetes deployments. We are actively involved in the Kubernetes community to ensure we listen to, and support our users’ and partners’ needs. Staying on top of security flaws, community issues and features to improve Kubernetes is critical to us. We keep the Ubuntu ecosystem updated with the latest Kubernetes, as soon as it becomes available upstream,” commented Ammar Naqvi, Product Manager at Canonical.

A Look into the Technical Details of Kubernetes 1.16

  • A Look into the Technical Details of Kubernetes 1.16

    Custom Resource Definitions (CRDs) were introduced into upstream Kubernetes by Red Hat engineers in version 1.7. From the beginning, they were designed as a future-proof implementation of what was previously prototyped as ThirdPartyResources. The road of CRDs has focused on the original goal of making custom resources production ready, bringing it to be a generally available feature in Kubernetes, highlighted with the promotion of the API to v1 in 1.16.

    CRDs have become a cornerstone of API extensions in the Kubernetes ecosystem, and is the basis of innovation and a core building block of OpenShift 4. Red Hat has continued pushing CRDs forward ever since, as one of the main drivers in the community behind the features and stability improvements, which finally lead to the v1 API. This progress made OpenShift 4 possible.

    Let’s take a deeper look at what will change in the v1 API of Custom Resource Definitions (in the apiextensions.k8s.io/v1 API group). The main theme is around consistency of data stored in CustomResources:

Custom Resources, Overhauled Metrics, and Volume Extensions

  • Hello Kubernetes 1.16: Custom Resource Definitions ease the creation and long term management of APIs

    Kubernetes 1.16 is expected to arrive this week, and with it comes a host of new changes that help ease management for users of this container orchestration platform. For users of Kubernetes, and of Red Hat OpenShift, this release signals the arrival of the general availability for Custom Resource Definitions (CRDs).

    When building open source software, duties and tasks must be distributed among large numbers of contributors, some of whom may even be in direct competition with one another. While this may sound like a risky, Machiavellian scenario, in practice, there’s far less rivalry. Instead, the whole project becomes a collaborative board game with individual high scores.

    Those high scores ebb and flow as teams take charge of features, lead them to completion and exchange leadership roles over the course of the development of the project. We say all that to say this: Kubernetes 1.16 saw a great deal of work and guidance across the ecosystem, as well as from Red Hat and Google (top upstream corporate contributors). All vendors and the community at large can benefit from the updates made in this release, especially with the prime time for CRDs, which are a main extension point for building cloud native applications on Kubernetes.

  • 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.
