codepipeline 不能输出yaml
codebuild & Codedeploy 无法集成
S3 输出需要有版本控制功能

I've currently been struggling with the same issue.

After some digging, I've found that it looks to be a limitation of linking the two services (codebuild and codedeploy) via codepipelines

Currently codebuild only supports ZIP/TAR/TGZ as the bundletypes (outputs) which codedeploy doesnt support

A work around is to trigger the codedeploy via the codebuild::project buildspec. Example below

export REVISION="revisionType=S3,s3Location{bucket=$BUCKET_DEPLOYMENTS,key=$CODEBUILD_BUILD_ID/appspec.yml,bundleType=YAML}"

aws deploy create-deployment \
    --application-name=$APPLICATION_NAME \
    --deployment-group-name=$DEPLOYMENT_GROUP_NAME \ 
    --revision=$REVISION \
    --deployment-config-name='CodeDeployDefault.LambdaCanary10Percent30Minutes'

    var bucket= event.bucket;
    var key= event.path;
    var bundleType='YAML';
    var REVISION= `revisionType=S3,s3Location{bucket=${bucket},key=${key},bundleType=${bundleType}}`
    var APPLICATION_NAME = event.APPLICATION_NAME;
    var DEPLOYMENT_GROUP_NAME = event.DEPLOYMENT_GROUP_NAME;
docker tag 78cd10d96f0c 852088822079.dkr.ecr.us-west-2.amazonaws.com/codebuild
    aws deploy create-deployment --application-name=DeployProduction --deployment-group-name=LambdaAliasDeploy --revision=revisionType=S3,s3Location{bucket=techsummit2019,key=codedeploy/appspec.yaml,bundleType=YAML} --deployment-config-name='CodeDeployDefault.LambdaCanary10Percent30Minutes' --region us-west-2
