win7设置docker默认服务端地址
win7设置docker默认服务端地址
win7通过
Docker Toolbox安装docker后，输入指令默认连接的是虚拟机中的default节点。连接远程docker服务时，需要使用docker -H tcp://ip:port [Commands]指令来操作，输入比较繁琐。通过添加bat脚本，实现自动添加-H tcp://ip:port参数。
1.开启docker远程访问
要本地连接远程docker服务，服务必须开启远程访问功能。参照开启docker远程访问设置服务器。
2.本地调整
2.1 docker.exe重命名
为保持使用习惯，bat脚本命名为docker.bat，命令行输入docker可直接调用。故需重命名docker.exe至docker2.exe防止冲突。
2.2 添加docker.bat
在Docker Toolbox根目录下新建docker.bat文件，内容如下。其中192.168.0.1:2375为开启docker远程访问中所开通的远程docker服务地址。Docker Toolbox目录需添加至环境变量。
@echo off
:: 清空参数字符串
set str=
:: 参数拼接
:joint
if "%1"=="" goto docker
set str=%str% %1
shift
goto joint
:: 指令与参数拼接
:docker
docker2 -H tcp://192.168.0.1:2375 %str%
2.3 添加快速切换功能
实际在使用时，我们可能有多台远程docker服务器，而有时也会连接本地docker。每次手动修改docker.bat太过繁琐，故在Docker Toolbox下添加脚本，快速切换docker默认服务端地址。
脚本命名为dockerip.bat(根据个人喜好随意修改)，只需命令行下输入dockerip，即可快速切换docker默认服务端地址。
