Boot2docker版本問題

Issue: 剛剛升級了docker client後，發現search不管用了，出現的錯誤是說明docker client與docker server的版本不一致所造成...

$ sudo docker search peihsinsu
FATA[0000] Error response from daemon: client and server don't have same version (client : 1.17, server: 1.14)

Solve: 在boot2docker中，要升級boot2docker的docker server的版本可以透過boot2docker upgrade來做到，系統會檢查目前client的版本來比照更新server的版本喔。
