The Golang corpus does not include a native debugger. It is possible to attach GDB to a go program, but the results are often disappointing on account of a lack of insight into the Go runtime (such as goroutines, etc). The obvious and perhaps idiomatic way to debug a Go application is with the tried and true printf+iterate model. However, there are several options above and beyond that may make certain problems easier to find.
derekparker/delve is a third party project that offers a comprehensive gdb-like, yet go-aware debugger. We won't reiterate the description or documentation here, but if you are looking for a way to debug a nasty problem, Delve does a pretty decent job.
You can run your go program with arguments (similar to gdb's "set arg") using the "--" parameter, as per here
kill -ABRT is a useful way to generate a stack trace of all goroutines, helpful if your program appears hung.
