win7設置docker默認服務端地址
win7通過
Docker Toolbox安裝docker后，輸入指令默認連接的是虛擬機中的default節點。連接遠程docker服務時，需要使用docker -H tcp://ip:port [Commands]指令來操作，輸入比較繁瑣。通過添加bat腳本，實現自動添加-H tcp://ip:port參數。
1.開啟docker遠程訪問
要本地連接遠程docker服務，服務必須開啟遠程訪問功能。參照開啟docker遠程訪問設置服務器。
2.本地調整
2.1 docker.exe重命名
為保持使用習慣，bat腳本命名為docker.bat，命令行輸入docker可直接調用。故需重命名docker.exe至docker2.exe防止沖突。
2.2 添加docker.bat
在Docker Toolbox根目錄下新建docker.bat文件，內容如下。其中192.168.0.1:2375為開啟docker遠程訪問中所開通的遠程docker服務地址。Docker Toolbox目錄需添加至環境變量。
@echo off
:: 清空參數字符串
set str=
:: 參數拼接
:joint
if "%1"=="" goto docker
set str=%str% %1
shift
goto joint
:: 指令與參數拼接
:docker
docker2 -H tcp://192.168.0.1:2375 %str%
2.3 添加快速切換功能
實際在使用時，我們可能有多台遠程docker服務器，而有時也會連接本地docker。每次手動修改docker.bat太過繁瑣，故在Docker Toolbox下添加腳本，快速切換docker默認服務端地址。
腳本命名為dockerip.bat(根據個人喜好隨意修改)，只需命令行下輸入dockerip，即可快速切換docker默認服務端地址。
