Running `go mod download` before copying the entire project to the Docker image avoids dependencies from being re-downloaded every time any file is modified, and `docker build` runs again. This follows the steps detailed in the official Docker guide for Go images: https://docs.docker.com/language/golang/build-images/#create-a-dockerfile-for-the-application Also, `GO111MODULE` doesn't make any difference for the supported Go versions, so it can be removed from the Dockerfile.
