If you don’t take any optimization measures, docker images can easily get large. And in most cases we just wrapped too many inessential things into the images. So, we should take actions to get rid of it. Let’s take a look at a common example Dockerfile for building an application written in Go. FROMgolang:1.10.2-stretch WORKDIR/go/src/github.com/ggicci/docker-example-server COPY . .
