Hope the installation of Kubernetes on AWS EC2 was easy, if you find any difficulty feel free to get assistance.Http -verbose elb=.com port=80 endpoint=/bravo/ sudo su –kubectl get pods -all-namespaces If it still doesn’t work, try refreshing the root profile by performing the command below and then running the prior command. Workflow: - Step-A1: Github repo, DockerFile,service.yml + deployment.yml for kubenetes and playbook. The result of the above command should show a large number of pods. Application Name: support system written in PHP with Symfony framework. You should see a list of two nodes, both of which should be in the READY state. You can wait for 2 minutes to verify whether the nodes are ready before running it on the master node. Calico is used to creating that overlay network.Ĭreate an Overlay network using Calico CNI plugin on the Master nodeįor calico networking, copy and paste the following commands and apply them solely to the master node. The third-party CNI plugins create this overlay network. This is because Kubernetes requires an “overlay network” for pod-to-pod communication to function effectively. The result of the following command will show both nodes in the NOTREADY status. Our cluster is now completed, and you can view it by running the command: kubectl get nodes Then initialize KUBECONFIG on both the master and worker nodes, so that kubectl commands can be executed. In Worker nodes:Īfter completing the cluster on the master node initialization you need to copy the kubeadm join command from the master node’s output. Then it will generate a command kubeadm join with certain tokens.
Sudo chown $(id -u):$(id -g) $HOME/.kube/config Sudo cp -i /etc/kubernetes/nf $HOME/.kube/config You can now copy and paste that into the same terminal or you can copy it from here and then paste it into the master’s terminal. The output screen of the master node will display the following commands. # sudo kubeadm init –pod-network-cidr=192.168.0.0/16 #Do this only if proper CPU cores are availableĪllow approximately 4 minutes. sudo kubeadm init -pod-network-cidr=192.168.0.0/16 -ignore-preflight-errors=NumCPU Systemctl enable kubelet & systemctl start kubeleįirst, let us initiate the cluster on the master node.

Installing kubeadm, kubectl and then start kubelet daemon yum install -y kubelet kubeadm kubectl -disableexcludes=kubernetes Sysctl command : to modify kernel parameters at runtime.ĭisable secure Linux to give access to kernel’s IP6 table. To deploy HPCC cluster on Kubernetes/AWS we need AWS Client and Kubernetes package. Now create yum repo files and use the yum commands to install the components of Kubernetes. Demo of Docker/Kubernetes on AWS Preparation. Systemctl enable docker & systemctl start docker Master and Worker nodes:īeing the root user, install Docker and then enable the Docker service, which will happen on system restarts. The small and medium-size businesses need to set themselves apart from the crowd. Now, enterprises are doing everything in the cloud from deploying business-critical applications to completing cloud backup processes. Cloud computing has evolved over the years. You should connect to both the ec2 instances using two putty terminals and decide which EC2 instance is the master and which is the worker. Leverage Docker, Microservices, Kubernetes and DevOps in AWS. Keep both of the AWS EC2 instances on the same VPC and same zone. Ensure all the ports are open in the respective security group.
If you’re using a centos-based system such as RHEL, so most of the commands remain the same. Show less Run Docker on AWS AWS provides support for both Docker open-source and commercial solutions.
Here we have used Amazon Linux 2 AMI, based on centos Linux. The Docker Engine is installed on each server you want to run containers on and provides a simple set of commands you can use to build, start, or stop containers.
You should have one AWS EC2 instance for each of the master nodes and worker nodes. Now let’s see all are the prerequisites that are needed. If you are looking to install Kubernetes on AWS EC2 instances from scratch, then this guide will make your steps easier.
