This tutorial deploys AIStor onto Kubernetes distributions that follow the upstream API and functionality. The steps in this procedure may work on forked Kubernetes distributions. This procedure requires the installation of Kubernetes operators and associated resources including CustomResourceDefinitions, Statefulsets, and secrets into new or existing namespaces. You must perform the operations in this procedure as a user that has broad permissions to create resources within multiple namespac...| AIStor Object Store Documentation

A ConfigMap is an API object used to store non-confidential data in key-value pairs. Pods can consume ConfigMaps as environment variables, command-line arguments, or as configuration files in a volume. A ConfigMap allows you to decouple environment-specific configuration from your container images, so that your applications are easily portable. Caution:ConfigMap does not provide secrecy or encryption. If the data you want to store are confidential, use a Secret rather than a ConfigMap, or use...| Kubernetes
Tools such as Prometheus and OpenTelemetry help us monitor the health, performance, and availability of our complex distributed systems. Both are open source projects under the Cloud Native Computing Foundation (CNCF) umbrella – but what role does each play in observability? OpenTelemetry (OTel for short), is a vendor-neutral open standard for instrumenting, generating, collecting, and exporting telemetry data. Prometheus is a fixture of the observability landscape, widely relied upon for m...| OpenTelemetry
Today we explore how the Kubernetes Operator pattern alleviates these issues and enables businesses to scale Apache NiFi.| Datavolo
Introduction: As Uber’s business grew, we scaled our Apache Hadoop (referred to as ‘Hadoop’ in this article) deployment to 21000+ hosts in 5 years, to support the various analytical and machine learning use cases. We built a team with varied expertise to address the challenges we faced running Hadoop on bare-metal: host lifecycle management, deployment and automation, Hadoop core development, and customer facing portals. With the growing complexity and size of Hadoop infrastructure, it ...| Uber Blog
With support for native clustering on Kubernetes, NiFi 2 provides a strong foundation for building scalable data pipelines. Unlocking the potential of NiFi on Kubernetes requires both foundational capabilities and supporting services, along with the knowledge to bring these elements together. The Datavolo distribution of NiFi incorporates best practices for performance and security, enabling customers to focus on creating multimodal data pipelines.| Datavolo

Kubernetes Operators are powerful tools when used right, pushing complex operations from human operators to code. This sounds great - and is in some cases - but often the tradeoffs operators expose are not taken into account, both by operator developers and users. This article goes over my take on when operators are useful and not, and what makes a good operator. A basic installation operator A common feature amongst almost all operators is the ability to deploy Kubernetes resources. For exam...| blog.howardjohn.info
With contributions from Sebastian Choren, Adnan Rahić and Ken Hamric. Kubernetes is an open source system widely used in the cloud native landscape to provide ways to deploy and scale containerized applications in the cloud. Its ability to observe logs and metrics is well-known and documented, but its observability regarding application traces is new. Here is a brief synopsis of the recent activity in the Kubernetes ecosystem: The first discussions started in December 2018 with a first PR on...| OpenTelemetry
This page describes the lifecycle of a Pod. Pods follow a defined lifecycle, starting in the Pending phase, moving through Running if at least one of its primary containers starts OK, and then through either the Succeeded or Failed phases depending on whether any container in the Pod terminated in failure. Like individual application containers, Pods are considered to be relatively ephemeral (rather than durable) entities. Pods are created, assigned a unique ID (UID), and scheduled to run on ...| Kubernetes
Custom resources are extensions of the Kubernetes API. This page discusses when to add a custom resource to your Kubernetes cluster and when to use a standalone service. It describes the two methods for adding custom resources and how to choose between them. Custom resources A resource is an endpoint in the Kubernetes API that stores a collection of API objects of a certain kind; for example, the built-in pods resource contains a collection of Pod objects.| Kubernetes
A Secret is an object that contains a small amount of sensitive data such as a password, a token, or a key. Such information might otherwise be put in a Pod specification or in a container image. Using a Secret means that you don't need to include confidential data in your application code. Because Secrets can be created independently of the Pods that use them, there is less risk of the Secret (and its data) being exposed during the workflow of creating, viewing, and editing Pods.| Kubernetes

The Operator Pattern from Kubernetes is an excellent way of handling tasks in a cluster in an automated way, for example, provisioning applications, running backups, requesting certificates, and injecting chaos testing. As a Nomad user, I wanted to do something similar for my clusters, so I set about seeing how it would be possible. It turns out; it is much easier than I expected! While Nomad doesn’t support the idea of Custom Resource Definitions, we can achieve an operator by utilising a ...| andydote.co.uk

tl;dr - There are at least two ways to wait for Kubernetes resources you probably care about: kubectl wait for Pods, initContainers for everything else One somewhat rarely talked about issue in Kubernetes land is how exactly people wait for stuff to happen. “Stateful workloads” can get hand-waved to using StatefulSets, and most intricate large deployable things (databases, etc) have Operators that you can use. Sometimes you just want to make sure a Service is up before you start a pod tha...| vadosware.io
