Docker is not the criteria for CI/CD?
My previous company had a mix of docker and non-docker environments. We still had a CI/CD pipeline. SCP'ing a single binary still counts as an automated deploy pipe, not sure what that has to do with anything.
Also: Go is only truly statically compiled if you turn CGO off. Otherwise it's relying on system libs, which means you might be surprised if you upgrade a server and forget the other. I've been there :)
