⚡️ Features and Enhancements

• Extend Copilot-generated CloudFormation templates with the Cloud Development Kit (CDK) or YAML Patch overrides (#4208, #4209)

  With the new copilot [noun] override command, you can now fully customize your environment, service, or job AWS CloudFormation templates generated from Copilot manifests.
  You can override templates using the CDK when you need the expressive power and safety of a programming language, alternatively you can apply YAML patches when you need only a handful modifications.

  To learn more about how to use overrides, checkout the CDK guide or the YAML patch guide.

• Add support for multiple listener rules for http and listeners for nlb for Load Balanced Web and Backend Services (#4170)

  You can now define multiple host-based or path listener rules for Application Load Balancers with the new http.additional_rules property. Similarly, you can define multiple listeners on different ports and protocols for Network Load Balancers with the nlb.additional_listeners field.

  Sample manifest file

  name: 'frontend'
  type: 'Load Balanced Web Service'
  
  image:
    build: 'path/to/Dockerfile'
    port: 8080
  
  sidecars:
     docs:
        port: 7000
        build: 'path/to/Dockerfile'
  
  http:
    alias: 'example.com'
    path: '/'
    additional_rules:
      -  alias: 'admin.example.com'
         path: '/'
         target_port: 9000
      -  path: '/docs'
         target_container: docs

  To learn more on how to add additional listeners and listener rules, see the manifest specification.

• Preview CloudFormation template changes with the new --diff flag (#4259)

  You can now run copilot [noun] package --diff or copilot [noun] deploy --diff to view the difference between your local changes and the latest deployed template.

• Enable building container images for sidecars (#4254)

  Previously, Copilot only supported taking a container image URL for sidecar containers. Now, you can use image.build for your sidecars just like your main container to build and push images from local Dockerfiles.

  To learn more see the guide for sidecar containers.

• Enable uploading local environment files for sidecar containers (#4447)

  Previously, you could only specify an environment file (env_file) for your main container. You can now specify an environment file to upload for any sidecar container.
