What is the recommended way to consume external resources (git repositories) as part of the deployment process? I am setting up a Serverless app on AWS with a static site hosted on S3. The lambdas and static site are hosted on individual repositories, and I am looking for ways to have a seamless integration between Pulumi handling the infrastructure and the deployment of those external contents. In addition, I am also looking to somehow have a continuous delivery from each lambda and static site repositories when commits are made to master. • Has anyone dealt with this already? • Are there any pitfalls to avoid? • Any reading material? Thank you
