When it comes to Kubernetes, it has replaced the drawback of hosting applications on a Virtual Machine or a physical server. We too need to provide resources to a Kubernetes resource for the container and workloads to consume.
In this article, we will be focusing on Assigning Resources to Kubernetes Containers and Pods, in detail.
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.

Advanced Kubernetes [Refcard Update]
Kubernetes is a distributed cluster technology that manages container-based systems in a declarative manner using an API. There are currently many learning resources to get started with the fundamentals of Kubernetes, but there is less information on how to manage Kubernetes infrastructure on an ongoing basis. This Refcard aims to deliver quick, accessible information for operators using any Kubernetes product.
Managing Kubernetes: From a Small Fleet to a Navy of Clusters
To keep pace with the ever-changing digital landscape, organizations are adopting open source and cloud native technologies at an incredible pace. But as the number of clusters and workloads grow, it can become increasingly difficult to know where clusters exist and how they are performing. And if multiple teams are provisioning and using clusters with different policies, roles, and configurations, you might as well jump ship. Because before you know it, you’ll begin to experience cluster sprawl, and your multi-cluster operations will potentially capsize before you reach shore. So how do you effectively monitor and manage disparate clusters and contain the chaos of sprawl?

Six Steps to Comprehensive Container Security
An application or service that you develop once to run in multiple clouds has a clear advantage over one that is bound to a single OS or runtime environment. Container technology makes it possible, but container security vulnerabilities are beginning to surface. We describe 6 steps you can take to ensure that container security doesn’t become a DevOps roadblock.

Kubernetes is a highly popular container orchestration platform. Multi cloud is a strategy that leverages cloud resources from multiple vendors. Multi cloud strategies have become popular because they help prevent vendor lock-in and enable you to leverage a wide variety of cloud resources. However, multi cloud ecosystems are notoriously difficult to configure and maintain.
This article explains how you can leverage Kubernetes to reduce multi cloud complexities and improve stability, scalability, and velocity.
Maintaining standardized application deployments becomes more challenging as your number of applications and the technologies they are based on increase. As environments, operating systems, and dependencies differ, management and operations require more effort and extensive documentation.
In the past, teams tried to get around these difficulties by creating isolated projects in the data center. Each project, including its configurations and requirements were managed independently. This required accurately predicting performance and the number of users before deployment and taking down applications to update operating systems or applications. There were many chances for error.
Kubernetes can provide an alternative to the old method, enabling teams to deploy applications independent of the environment in containers. This eliminates the need to create resource partitions and enables teams to operate infrastructure as a unified whole.
In particular, Kubernetes makes it easier to deploy a multi cloud strategy since it enables you to abstract away service differences. With Kubernetes deployments you can work from a consistent platform and optimize services and applications according to your business needs.
The Compelling Attributes of Multi Cloud Kubernetes
Multi cloud Kubernetes can provide multiple benefits beyond a single cloud deployment. Below are some of the most notable advantages.
In addition to the built-in scalability, fault tolerance, and auto-healing features of Kubernetes, multi cloud deployments can provide service redundancy. For example, you can mirror applications or split microservices across vendors. This reduces the risk of a vendor-related outage and enables you to create failovers.

A pod is the smallest deployable artifact that is created and managed by Kubernetes. Pods are compromised of one or more containers working together symbiotically. The pod is a shared execution environment, which means the pod has a set of resources that are shared by every container which is a part of the Pod.
The primary purpose of a multi-container Pod is to support co-located, co-managed helper processes for the main program. There are some general patterns of using helper processes in Pods.
➤ Design-patterns of Multi Container Pods
➤ Sidecar Design Pattern
Sidecar Design Pattern Imagine a container having a use-case, where there is a web server with a log processor, the sidecar design pattern aims to resolve this kind of exact problem. The sidecar pattern consists of the main application, i.e. the web application, and a helper container with a responsibility that is vital for your application but is not necessarily a part of the application and might not be needed for the main container to work.
➤ Adapter Design Pattern
The adapter pattern is used to standardize the output by the primary container. Standardizing refers to format the output in a specific manner that fits the standards across your applications. For instance, an adapter container could expose a standardized monitoring interface to the application even though the application does not implement it in a standard way.
➤ Ambassador Design Pattern
The ambassador design pattern is used to connect containers with the outside world. In this design pattern, the helper container can send network requests on behalf of the main application. It is nothing but a proxy that allows other containers to connect to a port on the localhost.
