docker mac performance
docker use linux kernel almost as native, so performance is well.
in mac or windows, things are different. there is no linux kernel.
so some helper needed.
docker-machine: a tool to install docker in virtual machine. Dockerized hosts (hosts with Docker Engine on them).
docker for Mac/Windows: even still run a virtual machine (super hidden ).with its own hypervisor “hyperkit” and shared file system “osxfs”. Unfortunately, “osxfs” wasn’t very fast.
but in many cases, realtime host-virtual consistence is not necessary.
So...
docker run exec
「docker run」コマンドは、コンテナを作成して起動するコマンド。

Containerが増える。
実質は：

「docker exec」コマンドは、起動中のコンテナ内で、指定したコマンドを実行するコマンド。
docker ps
docker exec -it container_id "/bin/bash"
docker-run options image_name init_command

-- rm (Container終了時削除）

It's safe to just delete the source directory and compiled package file. Find the source directory under $GOPATH/src and the package file under $GOPATH/pkg/<architecture>, for example: $GOPATH/pkg/windows_amd64.
example

The -i flag causes clean to remove the corresponding installed
archive or binary (what 'go install' would create).
