What does the `.wasp/out/Dockerfile` do?
Because it relies on package.json / package-lock.json, so it can't really be called from .wasp/out right? looks like a remanance of /out vs /build?

Hi @Zeko369. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

Based on the knowledge sources provided, I can offer some clarification about the
.wasp/out/Dockerfile in Wasp projects:
The .wasp/out/Dockerfile is actually a generated file that Wasp creates for deploying the server code. It's not meant to be called directly from the .wasp/out directory. Instead, it's part of Wasp's build process.
Here are some key points to understand:
1. Wasp generates a multi-stage Dockerfile by default, which is used to build and run a Docker image with the Wasp-generated server code and run any pending migrations.
2. The location .wasp/out/Dockerfile is likely where Wasp initially generates this file, but it's not the final location used for building.
3. During the wasp build process, Wasp copies necessary files (including src, package.json, and package-lock.json) into the .wasp/build directory. This is done to ensure all required files are in the correct build context for Docker.
4. The build process also replicates the project structure inside the Docker container to ensure relative imports work correctly.
5. Users can customize this Dockerfile by creating their own Dockerfile in the project's root directory. Wasp will append the contents of this custom Dockerfile to the bottom of the default multi-stage Dockerfile.
To see the actual Dockerfile that will be used for your project (which may combine Wasp's default Dockerfile with any custom additions), you can run:
This command will show you the final Dockerfile content that Wasp will use for building your project.
The confusion about /out vs /build is understandable. It appears that Wasp has gone through some restructuring, and there might be some remnants of the old structure. However, the current build process is designed to work with the necessary files in the correct locations.

Sorry @Zeko369, I seem to be having a bit of trouble. Don't worry though, I've pinged my support and they will try to fix me up! :technologist:
Perhaps try again in 15mins?Nope... didn't really help, but tnx for spending GPU time on this 🤣
One for @Filip maybe
@Zeko369 Good question!
The answer is - nothing 😄
.wasp/out and .wasp/build are generated using the same code (with a different dstDir argument). There is one exception (the sdk/wasp package, more on that here).
But, in essence, the build dir (used for production builds) mirrors the out dir (used for dev builds). We wanted to make those independent [1]. So, the Dockerfile in out is just there because it wasn't worth complicating the generating code just to remove it.
[1] Again, they currently aren't independent and that's something we want to address (see the above issue).Noice, makes sense
