Linux Tutorials
In this article, we will understand the basics of RBAC and create Role, ClusterRole, RoleBinding and ClusterRoleBinding Objects. We will then create a kubeconfig file to give limited access to a particular user on a selected namespace.
In this article, we will see an example of a resource limit and request for CPU and Memory. We will also use Metric Server. The Metrics Server is an aggregator of resource usage data in the cluster and it is not deployed by default in the cluster. We will use this Metric Server to see the resource consumption by pods.
Labels can be used to organize and to select Kubernetes objects. In this article, we will create a Pod with Labels to it and redirect the requests to it from the service using Selector. We will also perform get, delete operations on Pod and Service using Label/Selectors on the command line.
A namespace is helpful when multiple teams are using the same cluster. This is used when there is a potential of name collision. In this article, we will create a namespace and create a pod in the newly created namespace. We will also see how a namespace can be set as a default namespace.
In this article, we will see what a Terraform state is and how to manage it on an S3 Bucket. We will also see what “lock” is in Terraform and how to implement it. To implement this, we need to create an S3 Bucket and a DynamoDB Table on AWS.
Azure Virtual Network is one of the most important resources to create a private network in Azure. It enables many types of Azure services to communicate with each other securely. In this article, we will see the steps to create a Virtual Network and how to add a subnet to it.
Amazon Simple Queue Service (SQS) is a managed message queuing service of AWS which enables us to decouple and scale microservices, distributed systems, and serverless applications.
Amazon Elastic Block Store (EBS) is an easy-to-use, high-performance block storage service. It is like an external disk that can be attached to an EC2 Instance and used to store our data on it. This tutorial shows how to write a Lambda Function to delete Unused EBS Volumes.
A Network Load Balancer works at the fourth layer of the Open Systems Interconnection (OSI) model, the Transport Layer. It opens a TCP connection to the selected target on the port specified in the listener configuration. In this article, we will see the steps to create a Network Load Balancer, register instances, and access the Load Balancer using its DNS.
Security Groups (SGs) and Network Access Control Lists(NACLs) are the features that come with Virtual Private Cloud (VPC) in Amazon Web Services(AWS). In this article, we will see the steps to create an SG and NACL.
