Kubernetes, the open-supply box orchestration platform, has emerged as the solution for dealing with containerized applications. When deploying Kubernetes in the cloud, Amazon Web Services (AWS) gives a robust and scalable environment. In this manual, we can walk you through the manner of deploying Kubernetes on AWS step by step.

What is Kubernetes?

Kubernetes is an open-source box orchestration platform designed to automate deploying, scaling, and operating utility boxes. Developed through Google, and now maintained by the Cloud Native Computing Foundation (CNCF), Kubernetes offers a sturdy and flexible framework for coping with containerized programs in various environments, such as on-premises information facilities and public cloud providers like AWS, Azure, and Google Cloud Platform.

Key Features of Kubernetes

The following are the key features of kubernetes:

• Container Orchestration: Kubernetes automates the deployment, scaling, and control of containerized applications. It abstracts the underlying infrastructure, permitting developers to focus on the application logic.
• Scalability: Kubernetes can scale programs horizontally with the aid of including or removing off instances based on its utilization. This guarantees the most efficient overall performance and resource usage.
• Self-recuperation: Kubernetes monitors the state of applications and automatically restarts or replaces failed packing containers. It also can stabilize the burden and distribute community site visitors to healthy pods.
• Service Discovery and Load Balancing: Kubernetes provides DNS-based totally service discovery for containers, permitting seamless communication between services. It additionally offers built-in load balancing to distribute site visitors throughout a couple of pods.

How To Deploy Kubernetes on AWS?

The following are the steps that guides you on how to deploy the kubernetes on AWS:

Step 1: Create Ubuntu EC2 Instance

• Navigate to AWS Console and click on the launch instance

• Choose an Instance type: Amazon Ec2 Provides different types of Instances choose according to your usage. They are the Virtual server that can be run on application.

• Configure Instance: Configure your instance according to your requirement.

• Add Storage: You can add additional EBS Volume even after launching instance.

• Add Tag: Give Key , Value and then go to the next step.
• Configure Security Group: Select Security Group and then choose from them according to your need from the list, and then go the last step.

• Review Instance Launch: Review your instance and then click on the launch button.

Step 2: Install AWSCLI

• Try to unzip the python package with the following command:

apt install unzip python

Step 3: Install kubectl

• On executing the following command we can install the kubectl command line software:

chmod +x ./kubectl

• The following command helps in moving the kubectl file from current location to the local/bin directory:

sudo mv ./kubectl /usr /local /bin /kubectl

Step 4 : Create an IAM Role and attach

• You can create IAM role by going into role section and then click on the create a role.

\

• Attach the IAM role

Step 5: Create Kubernetes Cluster

• The following command helps in creating an updated kubernetes cluster

kops update cluster dev.k8s.valaxy.in --yes

Step 6: Validate Your Cluster

• Run the following command to validate the kubernetes cluster:

kops validate cluster

Troubleshooting Common Kubernetes Issues

The following are the some of the trouble shooting issues of kubernetes:

• Pod Scheduling Issues: Check resource requests/limits, node ability, and taints/tolerations.
• Networking Problems: Verify community regulations, carrier definitions, and DNS configurations.
• Persistent Storage Problems: Validate storage training, quantity permissions, and mount points.
• Cluster Unavailability: Check control plane, node health, and network connectivity.
• Performance Degradation: Analyze useful resource utilization, optimize software code, and scale resources if wanted.

Best Practices for Kubernetes

The following are the best practices of kubernetes:

• Resource Management: Define appropriate resource requests and boundaries for pods to prevent resource contention and make certain truthful useful resource allocation.
• Health Probes: Implement readiness and liveness probes to improve the reliability of applications. This facilitates Kubernetes know when a field is ready to serve visitors and whilst it need to be restarted.
• Labels and Annotations: Use labels and annotations efficiently to organize and categorize sources. Labels are used for identification, while annotations provide additional information of objects.
• Configurations and Secrets: Store configurations and sensitive records as ConfigMaps and Secrets respectively. Avoid hardcoding sensitive data in manifest files.
• Regular Updates and Backups: Keep Kubernetes and its additives updated with the contemporary solid releases. Regularly again up essential information and configurations to save you data loss.
