Using Rancher For Creating And Managing Kubernetes Clusters

How can we create and manage Kubernetes clusters on-prem or in Cloud? How can we manage our clusters across providers and regions? Can Rancher and Rancher Kubernetes Engine (RKE) help us with those and other similar tasks? Can we use it to manage clusters no matter whether they are in AWS, Azure, Google Cloud (GCP), DigitalOcean, Linode, VMWare, and other Cloud providers as well as in our own on-prem datacenters?

50+ Useful Kubernetes Tools for 2020 - Part 2


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 in the Cloud: Strategies for Effective Multi Cloud Implementations

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.

Kubernetes: Your Multi Cloud Strategy

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.

Kubernetes Cluster Federation With Admiralty

Kubernetes today is a hugely prevalent tool in 2021, and more organizations are increasingly running their applications on multiple clusters of Kubernetes. But these multiple cluster architectures often have a combination of multiple cloud providers, multiple data centers, multiple regions, and multiple zones where the applications are running. So, deploying your application or service on clusters with such diverse resources is a complicated endeavor. This challenge is what the process of a federation is intended to help overcome. The fundamental use case of a federation is to scale applications on multiple clusters with ease. The process negates the need to perform the deployment step more than once. Instead, you perform one deployment, and the application is deployed on multiple clusters as listed in the federation list.

What Is Kubernetes Cluster Federation?

Essentially, the Kubernetes cluster federation is a mechanism to provide one way or one practice to distribute applications and services to multiple clusters. One of the most important things to note is that federation is not about cluster management, federation is about application management.

Cluster federation is a way of federating your existing clusters as one single curated cluster. So, if you are leveraging Kubernetes clusters in different zones in different countries, you can treat all of them as a single cluster.

In cluster federation, we optimize a host cluster and multiple-member clusters. The host cluster comprises all the configurations which pass on all the member clusters. Member clusters are the clusters that share the workloads. It is possible to have a host cluster also share the workload and act as a member cluster, but organizations tend to keep the host clusters separate for simplicity. On the host cluster, it’s important to install the cluster registry and the federated API. Now with the cluster registry, the host will have all the information to connect to the member Clusters. And with the federated API, you require all the controllers running on our host clusters to make sure they reconcile the federated resources. In a nutshell, the host cluster will act as a control plane and propagate and push configuration to the member clusters.

Use Terraform to Create and Manage a HA AKS Kubernetes Cluster in Azure

Learn how to use Terraform to manage a highly-available Azure AKS Kubernetes cluster with Azure AD integration and Calico network policies enabled.

What is Azure Kubernetes Service (AKS)

Azure Kubernetes Service (AKS) is a managed Kubernetes offering in Azure which lets you quickly deploy a production ready Kubernetes cluster. It allows customers to focus on application development and deployment, rather than the nitty gritties of Kubernetes cluster management. The cluster control plane is deployed and managed by Microsoft while the node and node pools where the applications are deployed, are handled by the customer.

The AKS cluster deployment can be fully automated using Terraform. Terraform enables you to safely and predictably create, change, and improve infrastructure. It also supports advanced AKS configurations, such as availability zones, Azure AD integration, and network policies for Kubernetes.

Create a Local Kubernetes Cluster (K8s#3)

How to get a local Kubernetes cluster up and running

Hi everyone! With this article, we go deep with the Kubernetes Series. In the previous articles, I have shared with you a brief introduction to Kubernetes and showed the most common Docker parts used for Kubernetes.Today I want to show you 2 ways to setup a local Kubernetes cluster, that is the base you must have to start working with Kubernetes. These ways are the following :

  1. Setup minikube
  2. Setup Virtual Machines with Master and Worker nodes
