Kubernetes Dashboard WebUI

In this topic, we are going to consider the Kubernetes WebUI Dashboard. The Web User Interface allows us to browse our playground cluster and perform administrative tasks and things like that. It gives a good way to see what you have done on your playground without having to use the command line. So, let’s get started!


The first thing we do is to use kubectl apply command to apply the configuration to a resource by a specified filename. The resource name must be specified and if the resource does not exist it will be created.

In our case the file is provided by Kubernetes repo:


kubectl apply -f

Once we apply the recommended file, it will create the namespace for Kubernetes Dashboard that includes the Metrics Scraper and Dashboard.

If you want to take a closer look at what that yaml file does, you need to get it to your local system:


And then you can look at the content of Kubernetes Configuration through the sample of recommended.yaml file:

less recommended.yaml

We can see all of the separate Kubernetes objects that have been created by kubectl apply the command. The secrets, configuration map, role creation, the cluster role together with binding. By looking at this sample and the deployment itself you can learn a lot about the yaml format and you can see what it is actually doing to our playground cluster in order to install the Dashboard.

Moving forward to the next command

kubectl get pods --all-namespaces

We will see 2 pods are out there running - the Dashboard itself and the Scrapper. Another way to look at these would be:


kubectl --namespace=kubernetes-dashboard get pods

Here we need to specify the namespace.

Next, we need to create the yaml file in order to create an admin user in the Kubernetes Dashboard. Please paste the following to the admin.yaml file:

apiVersion: v1
kind: ServiceAccount
  name: admin
  namespace: kubernetes-dashboard

This file will create a Service Account called admin in the namespace kubernetes-dashboard.

Apply this file:

kubectl apply -f admin.yaml

Once we execute the file, it creates the Service Account admin. Next, we need to create the admin cluster role binding. Please paste the following to the admin_cluster.yaml file:

kind: ClusterRoleBinding
  name: admin
  kind: ClusterRole
  name: cluster-admin
- kind: ServiceAccount
  name: admin
  namespace: kubernetes-dashboard

It takes the Service Account we have just created and it creates a cluster role called admin_cluster.

Next, we need to apply that:

kubectl apply -f admin_cluster.yaml

The next command we are going to use is in the namespace kubernetes-dashboard where we will explore a secret. We have to do a trick here to get that secret:

kubectl -n kubernetes-dashboard describe secret $(kubectl -n kubernetes-dashboard get secret | grep admin | awk '{print $1}')

When we do that, we will see that we have an encrypted token. The point is to get the token for the admin user which we have created, copy it, and save it to use if for logging into the Kubernetes WebUI Dashboard. Please copy the token in any text file you want and save it for future use.

Moving forward, we are going to start the proxy in order to expose the Dashboard on your localhost and run it on a background:

kubectl proxy &

Now, if you have started your dashboard, not on a local machine you need to turn on the tunnel to your Kubernetes Dashboard to make it reachable from your localhost. Please open a new terminal window and run the following command:

ssh -g -L 8001:localhost:8001 -f -N <username@kubernetes_dashboard_hostname>

Once you run the command you can then use the following localhost:8001 Link

In order to token to the Dashboard, please copy the token from your text file and paste it, and click Sign in.

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.

(State of Kubernetes and Container Security, 2020)

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.

Microsoft Announces General Availability Of Bridge To Kubernetes

Recently, Microsoft announced the general availability of Bridge to Kubernetes, formerly known as Local Process with Kubernetes. It is an iterative development tool offered in Visual Studio and VS Code, which allows developers to write, test as well as debug microservice code on their development workstations while consuming dependencies and inheriting the existing configuration from a Kubernetes environment.

Nick Greenfield, Program Manager, Bridge to Kubernetes stated in an official blog post, “Bridge to Kubernetes is expanding support to any Kubernetes. Whether you’re connecting to your development cluster running in the cloud, or to your local Kubernetes cluster, Bridge to Kubernetes is available for your end-to-end debugging scenarios.”

Bridge to Kubernetes provides a number of compelling features. Some of them are mentioned below-

Did Google Open Sourcing Kubernetes Backfired?

Over the last few years, Kubernetes have become the de-facto standard for container orchestration and has also won the race against Docker for being the most loved platforms among developers. Released in 2014, Kubernetes has come a long way with currently being used across the entire cloudscape platforms. In fact, recent reports state that out of 109 tools to manage containers, 89% of them are leveraging Kubernetes versions.

Although inspired by Borg, Kubernetes, is an open-source project by Google, and has been donated to a vendor-neutral firm — The Cloud Native Computing Foundation. This could be attributed to Google’s vision of creating a platform that can be used by every firm of the world, including the large tech companies and can host multiple cloud platforms and data centres. The entire reason for handing over the control to CNCF is to develop the platform in the best interest of its users without vendor lock-in.
