I have a solution that allows you to benefit from precompilation cache even if you are building on a different machine!

> In my experience, deploying Julia to the cloud can be frustrating because it can be slow to build the container used to your app. [I](https://discourse.julialang.org/t/recommended-recipe-for-deploying-a-julia-app-in-docker-with-efficient-precompilation/95591) don’t [seem](https://discourse.julialang.org/t/julia-docker-aws-devops-workflow/109459/2) to be [the only one](https://discourse.julialang.org/t/rfc-cloud-container-infrastructure-management/112685/9). A major gripe is that AWS CodeBuild can’t do layer caching in a VPC, so strategies for rearranging your DockerFile to benefit from cache doesn’t help. I finally got a working solution for me. I build a base image with a SysImage of my dependencies and then copy my current src directory on deployment. Posting it here in case it is help…
