Docker and Kubernetes has revolutionized how we build and run the applications. In recent years containerization becomes new normal, and many organizations start using Kubernetes as Container Orchestration Platform. I was curious about Kubernetes and played with it a bit 3 years ago but I thought let’s wait and see is it going to be a real thing or just another over hyped technology. Now I see Kubernetes everywhere, especially where microservice architecture is used for their systems.

Intellij IDEA is the most popular IDE for Java development and there are tons of features to explore and become more productive. We all know about Live Templates which can be used to expand a small expression to common code snippets. Recently I came to know about File Templates, and I realized I can put it to good use and be more productive. First let us discuss the problem I was trying to solve with File Templates.

This is the 2nd part of our journey to learn SpringBoot application deployment and monitoring series. We are going to setup Jenkins build server and configure Pipelines for vote-service, bookmark-service and bookmarks-ui microservices. In this article we are going to learn: Implementing build pipeline using Jenkins Pipeline as Code Using Jenkins Shared Libraries Setting up pipelines using Job DSL You can find the GitHub repositories below: devops-setup https://github.com/sivaprasadreddy/devops-setup bookmark-service https://github.com/sivaprasadreddy/bookmark-service vote-service https://github.

This is the first part of our journey to learn SpringBoot application deployment and monitoring series. We will be using the following tools throughout the process, so please install them based on your operating system. Prerequisites Java 11, Maven (I would recommend using SDKMAN to install these tools) Docker, docker-compose VirtualBox Vagrant Ansible Minikube I will be using MacOS, Intellij Idea and shell scripting. You can use your favorite IDE, but try to use *nix like environment (Linux or MacOS) to be able to run those shell scripts.

Few years ago I wrote a series of blog posts on Developing a simple e-commerce application from scratch to production using SpringBoot. Well, I covered most of the development stuff but left “to production” part because other things came up. Many things changed since then. Now I want to write a series of articles focusing on deployment and monitoring. So, I am planning to build a simple application using SpringBoot and deploy it in different ways.

If you know me you know that I am a big fan of Spring ecosystem. I have been using Spring framework since 2007, and I am pretty familiar with many of its features. Even if we are familiar with some technology once in a while we get stuck with small issues and end up spending hours and hours figuring out why something is not working as expected. Spring framework is very flexible, and usually there are multiple ways to achieve the same thing.

If you ever worked on a large project which doesn’t have any tests then you know how painful it is to work on such codebase. You know what is more painful? Working on a project which has plenty of USELESS tests written for the sake of passing minimum code coverage requirement. Being a Professional Software Developer means more than solving a problem. One needs to learn how to write maintainable and testable code, write meaningful tests, know what to test and what not to test, how to evolve the codebase backing with a good set of test suite.

I was working on a SpringBoot application which is planned to deploy on AWS and, we were using S3, SQS and RDS services. LocalStack provides an easy-to-use test/mocking framework for developing AWS based Cloud applications. I want to use Localstack mock services instead of using real AWS services for two purposes: To run integration tests To run application locally We can use Testcontainers to spin up a Localstack docker container, but we need to configure Amazon service clients like AmazonS3, AmazonSQSAsync which is typical boilerplate that we copy-paste from project to project.

Nowadays software development is a challenging task as the number of programming languages, frameworks, libraries are increasing rapidly day by day. Luckily, the number of resources to learn on the internet for free also increased a lot. There are a ton of free resources to learn almost everything on the internet. There are lots of official documentation, blog posts, Udemy courses, YouTube videos etc. As a backend developer who primarily work on JVM based languages/frameworks like Java, Kotlin, SpringBoot etc, following are a collection of resources I usually follow to learn new things.

We all know how to run SpringBoot application in debug mode from our favorite IDEs(Eclipse/IntellijIDEA etc) and debug the code. Recently I had to debug a SpringBoot application which is running on a remote server. There is already lot of information on the Internet on how to remote debug java applications, but some approaches didn’t work for me. So, here I would like to share my findings. If application is running on localhost Suppose you are running your application on localhost only and remote debug from your IDE.
