Build preview environments for Amazon ECS applications with AWS Copilot

Introduction

In the software development sphere, immediate evaluation of every code adjustment and deploying pull requests to active environments for immediate preview and feedback is essential. This practice is instrumental in reducing post-deployment issues and operational disruptions, underscoring the urgency for dedicated preview environments. Without these environments, the risk of merging unassessed features into the primary codebase rises, potentially leading to substantial operational and project management challenges. To counteract this, this post explores the development of preview environments for Amazon Elastic Container Service (Amazon ECS) employing AWS Copilot, with a seamless integration with GitLab. In this structure, each change in the branch autonomously sparks the formation of a distinct environment in AWS ECS using AWS Copilot. This automation not only enhances preview accuracy but also accelerates the feedback loop, boosting the overall efficiency and reliability …
