virtualbox+vagrant學習-3-Vagrant Share-4-Vagrant Connect

Vagrant Connect

vagrant能夠共享到vagrant環境的任何或每一個端口，而不單單是SSH和HTTP。「vagrant connect」命令爲鏈接人員提供一個靜態IP，他們可使用該IP與共享的vagrant環境通訊。發送到此IP的任何TCP流量都被髮送到共享的vagrant環境。

 

1.Usage

即調用vagrant share --full命令

這將自動爲遠程鏈接共享盡量多的端口。更多信息請查看 the Vagrant share security page頁面。

注意在調用vagrant share --full命令末尾的共享名字，並將其提供給但願鏈接到你的機器的人。他們只須要簡單地調用vagrant connect NAME命令便可（和上一篇ssh的鏈接方法同樣）。這將給他們一個靜態IP，他們可使用它來訪問你的vagrant環境。

userdeMacBook-Pro:~ user$ vagrant share --full --http 80
Vagrant Share now defaults to using the `ngrok` driver.
The `classic` driver has been deprecated.

For more information about the `ngrok` driver, please
refer to the documentation:

相應虛擬機也已經打開：

 

2.How does it work?

vagrant connect的運行是經過作vagrant最擅長的事情:管理虛擬機來實現的。vagrant connect使用VirtualBox或VMware(更多的提供者支持即將到來)建立了一個只佔用20 MB內存的小型虛擬機。

而後，發送到這個小型虛擬機的任何流量都被代理到共享的vagrant環境，就好像它被定向到這個環境同樣。

$vagrant connect budget_hello:agenda_design

 

3.Beware: Vagrant Insecure Key

若是你正在使用的vagrant環境或box是受到vagrant不安全密鑰對(大多數公共box都是)的保護，那麼鏈接到SSH的任何人均可以輕鬆地使用SSH。

雖然你但願與你信任的人共享，但在某些環境中，你可能與類或conference共享，而且不但願它們可以SSH進入。
在這種狀況下，咱們建議從vagrant計算機中更改或刪除不安全的密鑰。

最後，咱們要注意，咱們正在努力使之在使用vagrant share時，除非顯式容許，不然vagrant私鑰將被主動拒絕。可是，這個特性尚未完成。
