KubeCost: Monitor Kubernetes Costs with kubectl

You already know you can take full control of all resources in a Kubernetes cluster using the kubectl client. There is a new open source kubectl plugin that enables kubectl to monitor costs now too. The cost plugin allows every engineering team to quickly determine the cost and efficiency for any Kubernetes workload in tandem with the open source Kubecost application.

Modern cloud infrastructure is increasingly complex, challenging teams beyond just operations and engineering. Financial controllers are under extreme pressure to allocate costs in order to monitor and improve financial performance of teams. They turn to engineering teams for answers. The collaboration between finance, operations and engineering enhances visibility of modern cloud workflows. As technology evolves, so does corporate culture. The cost plugin for kubectl is an answer to the challenges of modern enterprise infrastructure.

50+ Useful Kubernetes Tools for 2020 - Part 2

Introduction

Last year, we provided a list of Kubernetes tools that proved so popular we have decided to curate another list of some useful additions for working with the platform—among which are many tools that we personally use here at Caylent. Check out the original tools list here in case you missed it.

According to a recent survey done by Stackrox, the dominance Kubernetes enjoys in the market continues to be reinforced, with 86% of respondents using it for container orchestration.

And as you can see below, more and more companies are jumping into containerization for their apps. If you’re among them, here are some tools to aid you going forward as Kubernetes continues its rapid growth.

Kubernetes: Monitoring, Reducing, and Optimizing Your Costs

Over the past two years at Magalix, we have focused on building our system, introducing new features, and scaling our infrastructure and microservices. During this time, we had a look at our Kubernetes clusters utilization and found it to be very low. We were paying for resources we didn’t use, so we started a cost-saving practice to increase cluster utilization, use the resources we already had and pay less to run our cluster.

In this article, I will discuss the top five techniques we used to better utilize our Kubernetes clusters on the cloud and eliminate wasted resources, thus saving money. In the end, we were able to cut our monthly bill by more than 50%!

• Applying Workload Right-Sizing
• Choosing The Right Worker Nodes
• Autoscaling Workloads
• Autoscaling Worker Nodes
• Purchasing Commitment/Saving Plans

Kubecost - Cost Analysis with Kubernetes Monitoring

Introduction – Cost Analysis with Kubernetes Monitoring

As Kubernetes is becoming the leading container orchestration tool over the last couple of years, many companies are switching on it despite having a steep learning curve. When it comes to the cloud, many cloud providers are providing and helping small as well as big organizations to leverage the Kubernetes support. Companies are now transitioning their production environment on Kubernetes with cloud or on-premise infrastructure. The challenge they encounter firstly is that how the Kubernetes resources are allocated accurately to the different applications, services, teams, departments in the organization.

To understand why cost analysis of resources is important for an organization, let go back in the time of one to one deployments, having a single application running on a single server and the cost of that server would be effectively the cost of that application, so there is no confusion all resources are properly allocated. But as the containers came into the picture, we are getting out of this era. Multiple pods/containers are running per server which lowers the server fleet footprint, by this cost of running application improves and Kubernetes orchestrates those containers into logical blocks that maintain the level of abstraction which manages the low-level complexity such as the environment

Cost Analysis in Kubernetes

Based on the different resource category

• Compute- defines the charges for the nodes.
• Storage- defines the cost of Persistent disks and EBS volumes.
• Networking- defines external traffic charges, load balancing and so on.

And the logical components of Kubernetes cluster are categorized as:

• Admin includes API server, etcd, scheduler and everything you can find in the Kube-system namespace.
• Monitoring includes the stack of metrics- Prometheus.
• Logging- ELK stack.
• Applications- all the pods which handling the workload of the user.
• Idle- resources like CPU, memory, network.

Top Kubernetes Health Metrics You Must Monitor

Kubernetes is one of the most popular choices for container management and automation today. A highly efficient Kubernetes setup generates innumerable new metrics every day, making monitoring cluster health quite challenging. You might find yourself sifting through several different metrics without being entirely sure which ones are the most insightful and warrant utmost attention.

As daunting a task as this may seem, you can hit the ground running by knowing which of these metrics provide the right kind of insights into the health of your Kubernetes clusters. Although there are observability platforms to help you monitor your Kubernetes clusters’ right metrics, knowing exactly which ones to watch will help you stay on top of your monitoring needs. In this article, we take you through a few Kubernetes health metrics that top our list.

Crash Loops

A crash loop is the last thing you’d want to go undetected. During a crash loop, your application breaks down as a pod starts and keeps crashing and restarting in a circle. Multiple reasons can lead to a crash loop, making it tricky to identify the root cause. Being alerted when a crash loop occurs can help you quickly narrow down the list of causes and take emergency measures to keep your application active.

Kubectl cost: Monitoring Kubernetes Spend From the Command Line!

An open source tool for engineers to control how much they’re spending on infrastructure.

If you’re terminal-loving engineers using Kubernetes like us, kubectl is your constant companion. That’s why the Kubecost team built a new CLI for interacting with Kubernetes cost data. Today, we’re announcing kubectl cost, an open-source extension that fits directly into your workflow. Here’s an example of it in action:
