流氓文件中的Shell环境变量只能首先传递 [英] Shell environment variables in vagrant files are only passed on first up

问题描述

我正在运行Vagrant 1.8.5，它支持 Vagrantfile中的环境变量在配置时使用这样的格式

config.vm.provision：shell，path：bootstrap.sh env：
{MYSQL_DB_USERNAME=>django，
MYSQL_DB_PASSWORD=>supersecretpasswordwasreplaced}

然而，当我在没有配置的情况下，当我执行 up ，或者当SSH进入服务器来做任务时，我也希望这些环境变量也可用。我可以找到的明显的方法是将它们内置到框中（似乎过度杀伤），或者

$ b <

重复他们在我的 config.ssh。 forward_env ，以便它们可供供应商和SSH使用。

有更好的方法吗？

解决方案>

我不知道最好的最终方式 - 我看到这个问题不时出现和讨论。

在我的config.ssh.forward_env中重复它们，以便它们可供供应商和SSH使用。

好吧，这听起来像一个很好的解决方案，但有一些缺点，我已经讨论了在这问题已经

个人当我需要设置env变量时，我将它们添加到 .profile file：

  config.vm.provisionshell，privileged：false，inline：<< -SHELL 
 echoexport MYSQL_DB_USERNAME = django> /home/vagrant/.profile 
 echoexport MYSQL_DB_PASSWORD = supersecretpasswordwasreplaced> /home/vagrant/.profile 
 SHELL 
  

当您登录时，他们将可用

I'm running Vagrant 1.8.5, which supports environment variables in the Vagrantfile at provisioning time using a format like this

config.vm.provision :shell, path: "bootstrap.sh", env: {"MYSQL_DB_USERNAME"=>"django", "MYSQL_DB_PASSWORD"=>"supersecretpasswordwasreplaced"}

However, I would like these environment variables to also be available when I do up without provisioning, or when I SSH into the server to do jobs. The obvious ways I can find are

• to have them built into the box (seems like overkill) or
• repeat them in my config.ssh.forward_env so that they are available to both the provisioner and SSH.

Is there a better way?

解决方案

I am not sure about the best ultimate way - I've seen this question popping from time to time and discussion.

repeat them in my config.ssh.forward_env so that they are available to both the provisioner and SSH.

well, it could sound like a good solution but there's some drawback, I've discussed in this question already

Personally when I need to set env variable, I would add them in the .profile file:

  config.vm.provision "shell", privileged: false, inline: <<-SHELL
    echo "export MYSQL_DB_USERNAME = django" > /home/vagrant/.profile
    echo "export MYSQL_DB_PASSWORD = supersecretpasswordwasreplaced" > /home/vagrant/.profile
  SHELL

They will be available when you login.
