I'm pretty new to CLI docker and Unraid, so forgive my ignorance on aspects of this (if you can :D)
*I was able to finally make this fix above work after running through all my errors again and again with ChatGPT 4*
I downloaded and unzipped the docker-buildx.zip file above from @DanL onto my windows desktop and then uploaded it through my file manager plugin on UnRaid to the "custom" folder that is in the same directory as ' EFI, syslinux, extra ' etc... (by accessing it through my file manager plugin within UnRaid Settings)
I added the config changes shared by @mbush78 to my go file -- (also by accessing it through my file manager plugin within UnRaid Settings)
I ran into permissions issues and other things, likely because of previous attempts to install/get working the buildx plugin
Just for future reference for others out there who may stumble across this same issue...
From start to finish, is there a more efficient way to just CLI correct this issue with just a few commands strung together -- pulling the docker-buildx zip from a repository somewhere, unzipping it, moving it to the right directory, creating/editing text files, and bringing it all together?
Future new users will appreciate the help... I again apologize for my poor understanding of this. Learning everyday!
