Introduction AWS DynamoDB is a highly scalable, fast, and flexible NoSQL database that is a great choice for applications that require low latency and high throughput. In this tutorial, we will show you how to use AWS DynamoDB with Go and localstack to test our code. This guide will provide you with practical examples and explanations that will make it easy for you to use DynamoDB in your Go applications.
Introduction AWS Lambda is a powerful serverless computing platform that allows developers to run their code without worrying about the underlying infrastructure. In this tutorial, we will explore how to build and deploy AWS Lambda functions using Go and Docker. We will start by creating a new Lambda function in the AWS Management Console, then write some Go code to implement our function. We will then use Docker to build a container image of our code and deploy it to AWS.
Introduction In this post, we will learn more about Go programming language by implementing a Go version manager CLI tool. The goal of this CLI tool is to manage different versions of Go installed on our development machine. As part of implementing the tool, we will learn about command-line flags, bash completion, HTTP client to download archives and interaction with files or directories. Let’s dive into the requirements and the features we will support with the tool and the implementation of the tool using Go.
Introduction Mutual authentication with Transport Layer Security (mTLS) is a method for mutual authentication. It is often used in securing network communication between two services and ensures that the parties at each end of this communication are who they claim to be by verifying that they both have the correct private key. It has been a standard security and authentication mechanism in a service mesh like Istio, Linkerd, AWS App Mesh and others.
When working on a source code that has multiple contributors, it can be so that the feature branch that you are currently working on is behind by a few commits. This can happen when someone else on the team merges their commits to the main branch while you are working on the feature branch. To bring in the latest commits to your feature branch, you will need to either rebase to the main branch or merge the local main branch to your feature branch after pulling in the latest commits from the remote main branch.
