Kubernetes Day India 2019: Overview and Pro Tips for Attendees

Cloud, Container, and Kubernetes: Where it all beganMany companies today are adopting an all-in cloud strategy to tap the agility and speed the cloud offers. Business are resorting to Kubernetes Cloud providers to help adopt a robust cloud strategy. A great strategy helps them to connect to advanced capabilities such as blockchain and AI in real time.To run applications effectively in the cloud, a cloud-native approach is the best measure. Cloud-native means building and running applications that optimize the cloud computing delivery model. It suggests that the apps live in the public cloud, as opposed to an on-premise datacenter. Containers facilitate this smooth transition from on-premise to cloud by helping developers quickly spin up new, cloud-native workloads.The Cloud Native Computing Foundation (CNCF) is an open source software foundation dedicated to making cloud native computing universal and sustainable. Hence, the CNCF aims at promoting container and container orchestration technologies, emphasizing on the use case for Kubernetes.Kubernetes is an open-source container orchestration platform designed to automate the deployment, scaling, and management of containerized applications. Kubernetes makes it easy to deploy and operate applications based on a microservice architecture.Going by the trend in the past few years, Kubernetes enjoys unprecedented popularity as the most preferred cloud-native platform. (According to a survey conducted as part of a recent SDxCentral report on container and cloud orchestration, 64 percent of respondents said they were using Kubernetes, 36 percent said they were using Docker Swarm, and 18 percent said they were using Apache Mesos.) This makes Kubernetes the flagship project of CNCF, backed by tech giants like Google, AWS, Microsoft, IBM, Intel, Cisco, and Red Hat.Kubernetes Day, IndiaKubernetes Day India is the first ever CNCF event in India and is being hosted at the Infosys premises in Bengaluru.Kubernetes Day- a one day, single track event, brings together local and international experts for developers of all levels interested in Kubernetes and related cloud-native technologies. With this event, the CNCF aims at appealing to a large number of developers who might not necessarily travel to KubeCon + CloudNativeCon events in Europe, China, and North America.Talks range from introductory-level to advanced, given by speakers fromdiverse companies driving the technologies; andthe end users deploying them.The speakers are an eclectic blend of local and international tech experts, some of them being:Keynote from Liz Rice, Technology Evangelist, Aqua Security @lizriceNoobernetes 101: Top 10 Questions We Get from New K8s Users – Neependra Khare, CloudYuga Technologies & Karthik Gaekwad, OracleFirst Steps to Becoming a Kubernetes Certified Application Developer – Ben Hall, KatacodaHow to Secure Your Kubernetes Clusters – Cindy Blake, GitLabUsing Kubernetes API Effectively with Golang – Vishal Biyani, Infracloud.ioMaking Cloud-native Computing Universal and Sustainable – Dee Kumar, CNCFKubernetes for Java Developers – Arun Gupta, Amazon Web ServicesBuilding a PaaS for Robotics with Kubernetes – Dhananajay Sathe, Rapyuta RoboticsHow to Contribute to Kubernetes – Nikhita Raghunath, LoodseHow You Can Benefit by Attending Kubernetes DayThere are many reasons why engineers will attend the conference.

How you can achieve Continuous Deployment through Kubernetes

To achieve continuous deployment on AWS cluster through kubernetes we have to undertake the following tasks Make an environment for continuous deployment Create Jenkins job for CD First of all we will discuss about how to make an environment for continuous deployment. Before creating a cluster on AWS EC2 through kubernetes, we need to install some software in the client machine. The client machine could be an EC2 instance or desktop. We assume that our client machine is EC2 instance. These are the software we need to install on client machine: Java 8 Maven 3.x aws-cli Docker. Jenkins Git Now connect the EC2 instance through command line and change user to Jenkins. To connect EC2 instance, use the given command from the command line. $ssh -i " ubuntu@ Example $ssh -i "mypem.pem" ubuntu@ec2-35-160-126-78.us-west-2.compute.amazonaws.com Change user to Jenkins. A Jenkins user should have access to all the above software. Following are the Steps to Launch the Kubernetes Cluster on EC2: A. Create AWS profile. The command is given below for creating AWS profile $aws configure --profile B. Now export AWS profile $export AWS_DEFAULT_PROFILE = ; $export KUBERNETES_PROVIDER=aws; C. Download kubernetes version 1.5 $wget -q -o - https://github.com/kubernetes/kubernetes/releases/download/v1.5.7/kubernetes.tar.gz | bash $tar -xvzf kubernetes.tar.gz After unzipping the downloaded zip file, we get a kubernetes folder, which contains all the default configuration file for launching cluster on AWS, also we can override these configurations. The default setting is available in the location /kubernetes/cluster/aws/config-default.sh. Here are some configurations which are overridden. export KUBE_AWS_ZONE=eu-west-1c export NUM_NODES=2 export MASTER_SIZE=m3.medium export NODE_SIZE=m3.medium export AWS_S3_REGION=eu-west-1 export AWS_S3_BUCKET=mycompany-kubernetes-artifacts export KUBE_AWS_INSTANCE_PREFIX=k8s A better way to export is to keep this configuration into “.bashrc” file. D. Start and stop cluster Go to the given location to get script for start and stop /kubernetes/cluster/ Here you will get kube-up.sh and kube-down.sh for start and stop respectively. Also we can automate this to create a Jenkins job. The next important thing is to create a Jenkins job for continuous deployment. So let’s consider an example of spring boot microservice to deploy on AWS cluster. Assume a spring microservice has the following files which are mandatory for creating a Jenkins job. Dockerfile : This file is use for creating Docker container. Jenkinsfile: It has defined some steps on how Jenkins must perform a task in order to complete a job. Following are the tasks performed which are contained in the Jenkinsfile Clone the workspace Build project with running Junit test cases. Create an docker image Push docker image to docker registry (docker hub) Execute kubectl command for deploy docker image to aws cluster. Jenkinsfile code example. node { checkout scm stage('Run Test and Package') { sh 'mvn clean package' } stage('Create Docker Image') { docker.build("dockeraccout/myimage:1") } stage('Create Docker Image and push') { sh "docker login -u -p -e " docker.build("").push() } Stage(Deploy on cluster) { sh 'kubectl apply -f ./docker/deployment.yml' sh 'kubectl apply -f ./docker/service.yml' } }
