I'm honestly really confused about the specific role docker is playing here.

What, exactly, is Docker doing? Is it compiling the application? Is it making a runtime for the wasm binary? Is it being the runtime for the wasm binary, so the end user builds through whatever usual build processes and gets a binary they can then easily run?

If the wasm binary is lightweight and portable, why is docker useful?

edit: Given the other comments about "what problem does this solve" I think maybe the blog post has missed its mark slightly

Yeah. Not trying to be cynical, but this feels like someone at Docker said "we need to have a WASM story" and this is what they came up with. I really don't see the point.
