Kubernetes is hot and everyone loses their minds

We all witnessed Pat Gelsinger invite Kubernetes to vSphere and all of a sudden every IT manager on the planet needs to have a Kubernetes strategy. There are many facets to understanding and embracing Kubernetes as the platform of the future coming from a traditional IT mindset. Are we ready?

Forgetting IaaS

With the recent announcement from SUSE to abandon OpenStack in favor of their container offerings, where are we going to run these containers? Kubernetes does not replace the need to effectively provision infrastructure resources. We need abstractions to provision servers, networks and storage to run the Kubernetes clusters on. The public cloud vendors obviously understands this but are we simply giving the hybrid cloud market to VMware? Is vSphere the only on-prem IaaS that will matter down the line? Two of the biggest cloud vendors rely on VMware for their hybrid offerings. Google Anthos and Amazon Outpost.

Rise Above

In the new brave world IT staff needs to start thinking drastically different on how they manage and consume resources. New tools need to be honed to make developers productive (and first and foremost, happy) and not have them run off with shadow IT. There’s an apparent risk that we’ll leapfrog from one paradigm to another without understanding the steps necessary in between to embrace Kubernetes.

Since my first KubeCon in 2016 I immediately understood that Kubernetes is going to become the defacto "operating system” for multi-node computing. There’s nothing you can’t do on Kubernetes you did yesterday with headless applications. It gives you way too much for free. Why would you be stuck in imperative patterns with toil overload when the declarative paradigm is readily available for your developers and operations team?

Start now Mr. IT Manager

Do not sit around and wait for Tanzu and Project Pacific to land in your lap. There are plenty of Kubernetes distributions with native integration with vSphere that allow your teams to exercise the patterns required to be successful at deploying and running K8s in a production setting.

Here’s a non-exhaustive list with direct links to the vSphere integration of each:

Google Anthos

Rancher

Red Hat OpenShift

Juju

Kops

The Go library for the VMware vSphere API has a good list of consumers too. So start today!

It not only calculates the required fields but also pops out a window that draws the bit pattern and explains the results. With Windows 2000 and beyond Subnetting you do not have to do that anymore.īTW, if you need to calculate Subnet Masks and Network IDs and you can’t do it yourself (Duh, “Paper MCSE” or not?) you should try this fantastic Subnet Calculator right here: the result would have been 240 instead of 224. If you wanted 8 subnets, you had to calculate like you wanted 10, i.e.

#SUBNET MASK TABLE 4 BITS PLUS#

For example, if you wanted 2 subnets, you had to figure the number you wanted plus 2 – calculate like you wanted 4, i.e. Note: In Windows NT 4.0 you had to subtract 2 from the total number of available subnets. Only in Class C networks does the N value remain the same. In a Class B network instead of saying 5 (for example again, duh!) you must say 5+8. Therefore in a Class A network instead of saying 7 (for example) you must say 7+8+8. N=Number of Non-masked bits – Remember that in Class A and B networks you have other octets besides the one you’re subnetting. The table deals with Subnetting of only one octet. Use this table to help you calculate Subnet Masks, available hosts per subnet or number of subnets per class.

VMware выпустила обновление vSphere 7 Update 3

Компания VMware представила обновление Update 3 своей популярной платформы vSphere, а также программно-конфигурируемого хранилища данных vSAN

Благодаря этому VMware vSphere 7 получила целый ряд новых возможностей. В первую очередь следует отметить появление в платформе поддержки NVMe/TCP. Также, поскольку VMware рассматривает Kubernetes как направление для своего дальнейшего роста, значительно упростилась настройка VMware Tanzu. В vSAN 7 Update 3 была добавлена поддержка доступа ReadWriteMany в vSphere с помощью Tanzu, хотя ранее платформа поддерживала только режим доступа к томам ReadWriteOnce. Также стало известно о расширенной поддержке кластеров vSAN для кластеров Kubernetes.

В популярный программный продукт VMware vSAN был интегрирован виртуальный модуль для анализа статистики по вводу-выводу VMware I/O Analyzer в vCenter Server. Кроме того, был представлен новый интеллект для обеспечения плавного завершения работы кластера vSAN, чтобы данные и уровень контроля и управления оставались в желаемом состоянии.

Коснулось обновление и планировщика Distributed Resource Scheduler (DRS), в котором VMware изменила алгоритм в отношении обработки операции обслуживания. Благодаря этому более крупные и критически важные рабочие нагрузки будут перемещаться как можно меньше.

Стоит также отметить, что в обновление были добавлены дополнительный инструмент для мониторинга PMem-пулов, более глубокая интеграция с NSX, улучшения в PowerCLI, расширенная поддержка AI Enterprise + Bitfusion 4.0 для управления GPU-ресурсами, улучшенный механизм сопровождения ПО и оборудования, более удобные инструменты для развертывания локальных и гибридных облаков (включая также и cloud-init для более простой работы с гостями), переход к UEFI 2.4 и поддержка AMD VBS.

Важно помнить, что с выходом Update 3 ограничивается поддержка бездисковых конфигураций, имеющих только USB- или SD-накопитель. Связано это с изменением разбивки на разделы — единый том ESX-OSData подвержен гораздо более высоким IO-нагрузкам, что может привести к быстрому износу USB-диска или SD-карты.

Полный список новых возможностей доступен по ссылкам:

· для vSphere https://blogs.vmware.com/vsphere/2021/09/announcing-vsphere-7-update-3.html;

· для vSAN https://blogs.vmware.com/virtualblocks/2021/09/28/announcing-vsan-7-update-3/.

オンプレミス Kubernetes デプロイモデル比較

from https://qiita.com/tmurakam99/items/b27d1055f7c881a03ba0

各種 Kubernetes ディストリビューションの、オンプレミス向けデプロイモデル・アーキテクチャを比較してみました。概ね、私がデプロイを試してみたもの中心です。 なお各ディストリビューションはクラウド向けのデプロイにも対応していたりますが、本記事はオンプレ部分のみ記載するのでクラウドデプロイはばっさり省略します。

私の勝手な分類ですが、大きく分けると以下のようになります。

a) SW on Linux タイプ

b) Docker タイプ

c) 独自 OS タイプ

d) VM タイプ

a) SW on Linux タイプ

Linux　をインストールしたノードを用意し、この上にソフトウェアとしてインストールするタイプです。一番基本といえる形だと思います。

特徴としては、kubelet が Linux 上のデーモンとして起動し、それ以外のコンポーネントは Kubelet からコンテナとして起動されるという形になります。

Kubeadm

Kubeadm では、利用者が Linux OS とコンテナランタイム(Docker, containerd, cri-o など)、および kubelet のインストールまで行っておく必要があります。そのあと kubeadm を実行することによって、Control Plane, Worker の各コンポーネントをデプロイ、kubelet により起動されます。

Kubeadm を使う場合は、利用者が全ノードに kubeadm をインストールしてそれぞれのノードでデプロイ作業を実行する必要があるので、台数が多いと大変です。

Kubespray

Kubespray では、Ansible を使って各ノードに対して一斉にデプロイを実施します。Kubespray は内部で Kubeadm を使っているので、構成は Kubeadm を使った場合と基本的に同じです (etcd が kubelet 起動でないとか細かい違いはありますが)。

コンテナランタイムや kubelet のデプロイもやってくれるので、利用者が事前にやっておくのは Linux のインストールと ssh でログインできるようにしておくこと、sudo 使えるようにしておくこと、くらいです。

軽量ディストリビューション

以下軽量ディストリビューションも a) に分類できるかと思います。

b) Docker タイプ

Docker に依存するタイプです。実際のところ MKE や RKE は Linux には依存しているので、この分類はちょっと無理があるかもしれません。一応、kubelet が Docker の中で動くか、という観点で分類してみました。

kind (Kubernetes in Docker)

kind はその名の通り Docker コンテナ内で Kubernetes を動作させます。Docker コンテナ１つがノード(VM)1つ、というイ���ージです。

kind は開発・テスト用で、本番環境で使うものではありません。マルチノードクラスタに対応していますが、これは１つの物理or仮想マシン上で複数のVM(ノードコンテナ)をエミュレートできるという意味で、複数のマシンに跨ってクラスタを構成できるわけではありません。

MKE (Mirantis Kubernetes Engine)

MKE は Docker EE を買収した Mirantis の製品です。インストール手順はこちら

launchpad CLI から全ノードに対して ssh でログインして一斉にデプロイ可能で、Docker EE (MCR) のインストール、k8s のデプロイが実施されます。

RKE (Rancher Kubernetes Engine)

RKE は Rancher 社の製品です。

rke up コマンドで全ノードに対して ssh でログインして一斉にデプロイします。MKE と違い、Docker は事前にインストールしておかなければなりません。

なお、RKE の操作は CLI オンリーですが、Rancher Server を使用するとRKEクラスタ含む各種 Kubernetes クラスタの管理を GUI で行うことができます。

なお、上記は RKE1 の話で、RKE2 からは Docker には依存せず、containerd ベースになるようです。また Control plane は kubelet から static Pod として起動する形になるようです。

本題とずれますが Rancher/RKE は 100% OSS なのが良いです。他の商用製品は評価用はありますが本番で使うならライセンス購入が必要です。

c) 独自 OS タイプ

a), b) は OS は利用者が用意したものを使用しますが、このタイプは Kubernetes を動作させる OS 自体がディストリビューションに含まれているのが特徴です。

OCP (OpenShift Container Platform)

OCP はRedHat 社の製品 (OpenSource の OKD もあります)。OS には RedHat Core OS が使われています。

ベアメタルにインストールする場合は、物理マシンに Core OS をインストールし、この上に OpenShift をインストールすることになります。 ベアメタルにインストールする手順は ここにあります。インストール方法は以下の２通り。

IPI (Installer Provisioned Infrastructure)

インストーラが自動でインフラを構築する方法

各ノードをPXEブート(ネットワークブート)させ OS インストールする

UPI(User Provisioned Infrastructure)

ユーザが事前に用意してから構築する方法

ユーザが Core OS　の CD-ROM を用意して各ノードをブートする

どちらの方法でも外部にプロビジョニング用のマシン、DHCPサーバ、DNSサーバなど用意しなければならないので準備が大変です。

d) VM タイプ

Kubernetes　を稼働させるために専用の VM をデプロイするタイプです。

Minikube

Minikube は、Kubernetesが入った VM を立てるタイプです。Hyper-V や VirtualBox, VMware が使えます。また Docker も使えるので b) もできます。

なお、マルチノードクラスタは構成できません。シングルのみです。

Charmed Kubernetes

Charmed Kubernetes は Ubuntu で有名な　Canonical の製品。

インストール方法は何通りかあるのですが、シングルノードにインストールするときは LXD を使って VM を立ててデプロイするという形になります。デプロイ用のツールは Juju というものを使います。

マルチノードデプロイする方法としては MAAS(Metal as a Service) を使うようです。これはローカルにクラウド環境を構築するようなものなので、VMware vSphere に似ている感じです(試してはいないですが)

VMware vSphere with Tanzu

VMware vSphere with Tanzu は VMware 社の製品。仮想化基盤の vSphere を用意し���その上に Kubernetes 用の VM を立てるという方式になります。VM 内で動作する OS は Photon OS なので、ある意味 c) にも近いとも言えます。

物理ノードにハイパーバイザの ESXi をインストールし、この上に VM を立てます。クラスタノード全体の管理には vCenter Server を使います。⇒ アーキテクチャ

すでに vSphere を導入しているところに立てる場合は良さげですが、オンプレ Kubernetes クラスタ1個だけのためにこれを使うのはさすがに(運用が)重いかな、という印象。

Digital Transformation Helps Global SaaS Provider Achieve 300% Growth

Trintech is a rapidly growing financial software-as-a-service (SaaS) provider offering specialized accounting software that supports monthly, quarterly, and annual closings for large multinational companies. According to Matt Bertram, VP of Technology at Trintech, “our partnership with Dell Technologies, incorporating both Dell EMC PowerEdge and VMware Cloud Foundation, helped Trintech grow revenue by 300%, triple the number of SaaS customers supported on this infrastructure and increased operational efficiencies by more than 350%.” In addition, Matt reports that Dell EMC vSAN Ready Nodes running on Dell EMC PowerEdge servers increased IOPS by about 700%, while saving the company approximately 300% on SQL Server licensing costs.

The partnership began when Trintech set out to undertake an expansion and acquisition plan that would quintuple its employees and triple its customer base over a two-and-a-half-year period. To avoid growing pains, the IT team needed a reliable way to quickly roll out data centers on a global scale. Matt knew that digital transformation was the key to achieving the efficiency, flexibility, scalability and ease of deployment and management he would need to support the business though this expansion period and beyond.

Because of all these needs, Matt looked for a technology partner that could help him transform and modernize IT with a flexible foundation for growth. Matt selected Dell Technologies, saying “we knew that by continuing to grow, we would be able to leverage different Dell Technologies and VMware solutions that would provide us with generational leaps in terms of performance, availability, and overall resiliency within the global infrastructure.”

Trintech supports thousands of financial services customers worldwide, using Microsoft SQL Server for a range of customer facing SaaS applications. Trintech has invested in artificial intelligence (AI) and automation, integrating these with Microsoft SQL Server, enabling bots to perform routine functions for Trintech’s accounting and financial services customers.

By virtualizing SQL Server workloads on Dell EMC PowerEdge servers, Trintech was able to transition to VMware clusters, recognizing significant savings in compute utilization and storage along with significant performance gains and an enhanced ability to meet business continuity and disaster recovery (BCDR) objectives across a complex global infrastructure. This new infrastructure enabled the company to support 3x the number of SaaS customers, which drove a 3x increase in revenue.

Dell EMC OpenManage Enterprise was a critical tool for enabling rapid global expansion, with Matt sharing: “we saw a 350% increase in work done by infrastructure and operations teams, and we were able to deploy multiple data centers in new geographic regions within hours to weeks instead of multiple months.”

Matt and his team plan to build on their initial success by continuing to upgrade their VMware Cloud Foundation environments, including deploying VMware vSphere 7 and leveraging VMware Tanzu for Linux and Windows containers. This will enable Trintech to automate DevOps with a future-focused Kubernetes platform for cloud-native apps. Matt anticipates that “we will be able to decrease the time to deploy new versions of our product from hours to seconds.”
