• AWS S3: Bucket Policy vs. Access Control List (ACL)

    Introduction

    Securing the objects stored in Amazon S3 (Simple Storage Service) is crucial for protecting sensitive data. When it comes to implementing access control, there are two commonly used methods: Bucket Policies and Access Control Lists (ACLs). These mechanisms allow administrators to define fine-grained permissions for their S3 buckets and the objects within. In this blog post, we will explore the differences between Bucket Policies and ACLs, how they function, and when it’s appropriate to use each.

  • How to Delete Files Recursively from an S3 Bucket

    Introduction

    In this article, we will guide you through the process of deleting files recursively from an S3 bucket in Amazon Web Services (AWS). Deleting files recursively allows you to remove not only the files present in a specified directory but also all the files and subdirectories within it.

    Throughout this guide, we will provide step-by-step instructions, discussing the installation and configuration of the AWS CLI, listing objects in the bucket, and deleting files recursively using the aws s3 rm command with the --recursive flag.

    Please note that the deletion process is irreversible, so exercising caution is essential. Now, let’s delve into the details and start deleting files recursively from your S3 bucket.

  • How to pass Environment Variables to AWS CodeBuild BuildSpec

    Introduction

    Building and deploying software applications in the cloud can be a complex process, especially when it comes to managing sensitive data and configuration settings. In the context of AWS CodeBuild, environment variables play a crucial role in securely passing this information to your build processes.

    In this blog post, we will explore how to effectively pass environment variables to AWS CodeBuild BuildSpecs. We will start by understanding what BuildSpecs are and why environment variables are important in this context. We will then dive into the process of defining environment variables within the BuildSpec file and referencing them in your build commands.

    Additionally, we will explore the integration between AWS CodeBuild, AWS Parameter Store and AWS Secrets Manager, which enables you to securely retrieve sensitive data during the build process. By the end of this post, you will have a clear understanding of how to leverage environment variables to manage secure configuration settings and sensitive data in your AWS CodeBuild projects.

    So, let’s get started and learn how to pass environment variables to AWS CodeBuild BuildSpecs effectively!
