Reading Time: 6 minutes Hello Readers! In this blog we are going to see all about kontena lens-Beautiful kubernetes UI. Here we will see how to use the kontena lena user interface to manage multiple kubernetes clusters at the same time. This does not only provide a beautiful and interactive UI but also we can use it for accessing and managing configurations of your cluster. So, let’s get start Continue Reading
Reading Time: 6 minutes Hello Readers, Today the majority of organisations adopted micro services architecture and the rest are planning to migrate to it one of the important reasons for this is making their application highly available to consumers. For this reason many organisations use the kubernetes platform so that they will have high availability with zero downtime as kubernetes has many important key features like Replication, Load Balancing, Continue Reading
Reading Time: 9 minutes This blog contains a detailed description for creating an AWS EKS Cluster by CloudFormation. We will see how we can set up this through AWS Cloud Formation with a working example. Introduction Amazon Elastic Kubernetes Cluster (EKS) is a AWS managed service which can be used to run Kubernetes in which control planes or nodes are maintained by AWS. Like any other service offered by Continue Reading
Reading Time: 3 minutes Introduction to Kubernetes Kubernetes is an open-source container orchestration platform (Originally developed by Google) designed to automate the deployment, scaling, and management of containerized applications. Kubernetes makes it easy to deploy and operate applications in a microservice architecture. What is GKE? Google Kubernetes Engine is a Management and orchestration way for Containers. The goal of GKE is to increase the potency of DevOps and development teams by comprising Continue Reading
Reading Time: 4 minutes What is Service? Service is an abstraction level that Kubernetes uses to make a deployed application accessible from the internal and external of the cluster. Think time… Imagine that, you have been asked to deploy a web app How front-end web app is exposed to the outside world ? In what way will we connect front-end with back-end and database? How do we resolve Pod IP Continue Reading
Reading Time: 5 minutes In our current scenario, we have 4 Node cluster where one is master node (HDFS Name node and YARN resource manager) and other three are slave nodes (HDFS data node and YARN Node manager) In this cluster, we have implemented Kerberos, which makes this cluster more secure. Kerberos services are already running in the different server which would be treated as KDC server. In all Continue Reading
Reading Time: 3 minutes Hi readers, In this blog, we will be setting up a Kafka Statefulset cluster using Kubernetes and also get a basic knowledge of Statefulset. StatefulSet StatefulSet is the workload API object used to manage stateful applications. Manages the deployment and scaling of a set of Pods, and provides guarantees about the ordering and uniqueness of these Pods. Kafka Apache Kafka is an open-source stream-processing software platform developed by Continue Reading
Reading Time: 3 minutes Akka cluster provides a fault tolerant decentralized peer to peer cluster membership service with no single point of failure or single point of bottleneck. It does this using gossip protocol and an automatic failure detector.
Reading Time: 4 minutes Recently got the task to install DC/OS on our local cluster. Previously I used AWS to install DC/OS, but this time I had to do everything on our own, from installing CentOS to creating the DC/OS cluster. With this blog, I am going to share my experience that I faced in installing DC/OS. It took almost three days, but at the end I successfully installed Continue Reading
Reading Time: 2 minutes We are developing huge applications and deployed on multiple virtual machines and clusters. For monitoring applications, we need to enable logs into our application and analysis that logs with help of some tools like elastic stack. But !! what if we need to check health of application on virtual machines and clusters? For that, we are using several Metrics for system health check like Gauges, Continue Reading
Reading Time: 2 minutes In one of our previous blog, Setup a Apache Spark Cluster in your Single Standalone Machine, we showed how to setup a standalone cluster for running spark applications. But we never discussed on how to deploy our Spark applications on that cluster. So, in this blog, we will see how to deploy our Spark application on a cluster and use it to run our spark jobs. For Continue Reading
