How to provide AppSpec and Task Definition to CodeDeploy in ECR sourced pipeline

Question

I want to trigger a blue/green ECS deploy on ECR image update. The deployment stage requires three input artifacts: imageDetail.json, appspec.json and taskdef.json.

While creating a pipeline I pick ECR repository as a source, which creates an imageDetail.json SourceArtifact, this is clear. Later in a build stage I can put it in output artifacts.

What I miss completely is how to provide the two remaining files? Should I inline them in the build stage definition buildspec.yaml (they are quite big and inlining seems tedious) or fetch them somehow from CodeCommit (so far I thought I can do it without having to set up CodeCommit only for that purpose)?

What is the usual practice for providing those files?

Yes, you will need to source the other files from a Code repository (github/CodeCommit). This tutorial is a nice guide on the ECS/CodeDeploy deployment pipeline:
