I want so hard to like docker, but docker sure doesn’t make it easy. Consider trying to copy a file in a dockerfile to a destination with a space in it. You’re likely to get an error about how a path doesn’t exist. If you Google this problem you get great adivce which basically adds up to “Don’t put spaces or whitespace in your file paths”. Thanks.
There are two approaches to putting spaces or whitespace in that I’ve found. The first is to use a variable
The other is to use this insane quasi-json syntax
Take your pick.
