最近在使用window上的docker toolbox
這個docker是基于virtual box虛擬機(jī)的+power shell架設(shè)的，自帶圖形管理Kitematic (Alpha)
但是眾所周知，docker的官方HUB在國外，慢得1逼，國內(nèi)的建議使用DAO Cloud的加速服務(wù)器對映像服務(wù)進(jìn)行加速,但是因為多了一層VM，使操作docker的時候顯得格外繁瑣。現(xiàn)分享一點(diǎn)過程與思路：
虛擬機(jī)入口：
實際上執(zhí)行的命令：
實際上運(yùn)行的命令是：
"C:\Program Files\Git\bin\bash.exe" --login -i "C:\Program Files\Docker Toolbox\start.sh"
看上去像是用了power shell 執(zhí)行Docker Toolbox的腳本了，那么前者沒有價值，現(xiàn)在需要看看start.sh的內(nèi)容：
#!/bin/bash
trap '[ "$?" -eq 0 ] || read -p "Looks like something went wrong in step ′$STEP′... Press any key to continue..."' EXIT
# TODO: I'm sure this is not very robust.? But, it is needed for now to ensure
# that binaries provided by Docker Toolbox over-ride binaries provided by
# Docker for Windows when launching using the Quickstart.

如上所述，這個腳本的功能就是：
先檢查一下同名的叫做default的虛擬機(jī)是否已經(jīng)在virtualbox里面存在
如果不存在就調(diào)用virtualbox的create api 新建一個，同時帶上docker運(yùn)行時候的參數(shù)，包含我們要設(shè)置的registry mirror
關(guān)于這個國內(nèi)加速的registry mirror URL可以在https://www.daocloud.io/申請，詳情不在敘述，再次感謝daocloud為國內(nèi)docker社區(qū)推廣和貢獻(xiàn)
如上，把你的URL加到上面的create 語句中，docker設(shè)施就能生效
值得注意的是，因為這個只在create過程中設(shè)置，所以如果同名虛擬機(jī)已經(jīng)存在，就不會再create，新的升值也不會生效。
