AWS Copilot adds support for full customization with AWS CDK or YAML overrides

Today, AWS released new version 1.27 of AWS Copilot that enables customers to fully customize AWS Cloud Formation templates, which AWS Copilot uses to provision the service, environment, pipeline, and job resources. Customers can now use AWS Cloud Development Kit (CDK) or YAML patches to change any property of those AWS resources. AWS Copilot is a command-line interface (CLI) that makes it easier for customers to build, deploy, and operate containerized applications on AWS by providing common application architecture and infrastructure patterns, user-friendly operational workflows, and configuring deployment pipelines.

With the new AWS Copilot release (1.27) users can now run copilot svc override, copilot env override, or copilot job override to enable overrides of any property of a service, environment, or job . Users can choose between two options --tool cdk or --tool yamlpatch overrides. With CDK overrides, AWS Copilot bootstraps a new CDK application inside a copilot/<resource name>/overrides/ directory of the user’s project and provides instructions inside stack.ts file on how to use the CDK. Customers can start by editing stack.ts and modify any properties of AWS Cloud Formation resources generated by AWS Copilot before a deployment. Customers who choose to use YAML patch overrides can override the AWS Cloud Formation template via .yaml patch files that adhere to the JSON patch syntax. Both options give customers full control over AWS resources and their properties that AWS Copilot deploys.

The feature is available in all regions when using AWS Copilot 1.27 release. To learn more, visit docs.
