Should probably base it off an Alpine image instead. Would make it many times smaller. [edit] In fact, there is a "golang:1.10-alpine" Docker image: mike@ung:~$ sudo docker image ls|grep alpine golang 1.10-alpine 05fe62871090 4 days ago 376MB mike@ung:~$ Hmm. even that one is bigger than I expected.
