CLI

cmdでは実行パスを通してからocコマンド利用。

C:\>cd c:\drive

c:\drive>minishift.exe oc-env
SET PATH=C:\Users\hoge\.minishift\cache\oc\v3.6.0\windows;%PATH%
REM Run this command to configure your shell:
REM     @FOR /f "tokens=*" %i IN ('minishift oc-env') DO @call %i

c:\drive>SET PATH=C:\Users\hoge\.minishift\cache\oc\v3.6.0\windows;%PATH%

    ---------
    Node.js 6 available as docker container is a base platform for building and
running various Node.js 6 applications and frameworks. Node.js is a platform bui
lt on Chrome's JavaScript runtime for easily building fast, scalable network app
lications. Node.js uses an event-driven, non-blocking I/O model that makes it li
ghtweight and efficient, perfect for data-intensive real-time applications that
run across distributed devices.
