Yes, just using built-in packages, and not depending on too many third-party packages is definitely attractive to me. The code full of "if err != nil" is an issue that I've also noticed. However, I'm hopeful that this may actually remind me to be more exhaustive in error handling.

Why did you mention the container? How kind of benefits would you be getting from a container for Go?

A container is just useful. But given Go's static binaries, you could also just ship the binary over to a server and be up and running. But it's nice to just have a container with all the bits/config inside that you can just copy over. The benefits of a container are the same for any language.
