Learn Kubernetes for Microservices

As a microservice developer working with Kubernetes, there are several key concepts and components you should familiarize yourself with to effectively deploy and manage microservices in a Kubernetes environment. Here's a list to get you started:  
  • Containerization Basics: Understand the fundamentals of containerization, particularly Docker, as Kubernetes relies heavily on containerized applications. 
  • Kubernetes Architecture: Learn about the key components of the Kubernetes architecture, such as the control plane (API server, controller manager, scheduler, etcd), and nodes (worker machines). 
  • Kubectl Command-Line Tool: Get familiar with kubectl, the primary command-line interface for interacting with Kubernetes clusters. Learn common commands for deploying, managing, and monitoring applications. 
  • Pods: Understand the concept of pods, which are the smallest deployable units in Kubernetes. Pods encapsulate one or more containers and share network and storage resources. 
  • Deployments: Learn about Deployments, a higher-level abstraction that allows you to declaratively manage the desired state of your application, including scaling, rolling updates, and rollbacks. 
  • Services: Understand Kubernetes Services, which provide stable network endpoints to access a set of pods. Services enable load balancing, service discovery, and routing traffic to pods. 
  • ConfigMaps and Secrets: Explore ConfigMaps for managing configuration data and Secrets for securely managing sensitive information, such as passwords and API keys. 
  • Persistent Volumes and Persistent Volume Claims: Learn how to manage persistent data in Kubernetes using Persistent Volumes (PVs) and Persistent Volume Claims (PVCs). 
  • Ingress: Understand how to use Ingress controllers to manage external access to services within the cluster. Ingress allows you to define routing rules and host-based routing. 
  • Resource Limits and Quotas: Learn how to set resource limits and quotas to ensure fair resource usage and prevent resource exhaustion. 
  • Health Checks: Implement health checks in your applications, as Kubernetes uses them to determine the readiness and liveness of your pods. 
  • Monitoring and Logging: Explore tools and best practices for monitoring and logging within a Kubernetes cluster, such as Prometheus, Grafana, and Fluentd. 
  • Helm Charts: Familiarize yourself with Helm, a package manager for Kubernetes, to define, install, and upgrade even the most complex Kubernetes applications. 
  • Networking in Kubernetes: Understand Kubernetes networking concepts, including Services, Ingress, and network policies. 
  • Security Best Practices: Learn about security best practices for Kubernetes, including RBAC (Role-Based Access Control), Pod Security Policies, and securing container images. 
  • CI/CD Integration: Integrate your Kubernetes workflows with CI/CD tools to automate the deployment, testing, and scaling of your microservices. 
  • Custom Resources and Operators: Explore Custom Resource Definitions (CRDs) and Operators to extend Kubernetes with custom resources and controllers for managing complex applications. 
  • Kubernetes API: Understand how to interact with the Kubernetes API programmatically, which can be useful for automation and custom integrations. Remember that Kubernetes is a vast and evolving ecosystem, so ongoing learning and staying updated on new features and best practices are essential for effective microservices development in Kubernetes environments.

Spring Boot And Angular 4 with Angular CLI Integration

I recently spent the time to setup Angular CLI front-end using IntelliJ and Maven tool. Angular 4 is the next version of Angular 2. In this article, I am going to show how to integrate Angular 4 with SpringBoot RestAPI using IntelliJ step by step. In this article,  1. I used various technologies.  -> Maven  -> IntelliJ  -> SpringBoot  -> Java 8  -> Angular 4  ->Node.js  2. Setup Node.js and NPM.  Install Node.js from Download . And then check Node.js and NPM by node -v and npm -v command respectively. -> Open CMD in Windows and check Node.js and NPM: node -v and npm -v.   3. Install the Angular-CLI using the command line as:  -> open cmd and type npm install -g @angular/cli -> and check Angular-CLI after installing as: ng -v 4. Setup SpringBoot App using IntelliJ as: -> create a simple spring-boot restful app and dependency for the web in pom.xml file as < dependency > < groupId > org.springframework.boot </ groupI

Introduction of Regular Expression

Regular expression is an special kind of API for finding sequence of character that specifies a pattern which can be searched for in a text and data. Usually regex or regular expression can be use to search,  edit and manipulate text and data. Java Regex API provides one interface and three classes in java.regex.util package. 1. MatchResult interface A MatchResult interface represents the result of match operation. It contains query methods used to determines the results of a match against a regex. 2. Matcher class    It is a regex engine that  interprets the pattern and perform match operations on a character sequence. 3. Pattern class A Pattern object is an compiled representation of a regex. 4. PatternSyntaxException class A PatternSyntaxException object is an unchecked exception that indicates a syntax error in a regex pattern. Predefined Character classes Construct Description . Any character (may or may not match line terminators) \d A digit:  [

String vs StringBuffer vs StringBuilder

What is the difference between String, StringBuffer and StringBuilder? String: Java String object is an immutable i.e. unmodifiable. It can be created by two ways by literal and new keyword. StringBuffer: Java StringBuffer is mutable. It can be created by using the new keyword. It is a synchronized means thread-safe. StringBuilder: Java StringBuilder is mutable. It is non-synchronized means not thread-safe.
