配置一个 vagrant box 需要多次尝试
Provisioning a vagrant box takes multiple tries
"Insanity: doing the same thing over and over again and expecting
different results." - Albert Einstein
我有一个 vagrant + chef (w/chef-zero Berkshelf) 构建的盒子，其中 运行 有很多程序，包括 zend-server-php、mongos 和 erlang。我使用的是流行的食谱，由 Berkshelf 管理，还有一个基本的 CentOS 6 盒子（存储在我的本地 Mac 上）。第一次（在 vagrant destroy 之后）启动这个盒子通常需要多次尝试。 vagrant up 将在上面列出的其中一个程序上失败，我将不得不一遍又一遍地 运行 vagrant provision （有时多达 6 次）来完成整个构建没有错误。然而，在极少数情况下，星星对齐，第一次尝试一切都会点燃。
我看到的错误通常是明确的超时错误（尽管并非总是如此）。我通常 运行 从一个相当弱的办公室网络连接（<20 Mbps 下降）进行此操作，这可能解释了为什么在最大下载量时发生故障。
所以这是我的问题：首先，除了网络连接之外是否还有其他变量在起作用，这可以解释为什么我必须多次 vagrant provision？如果是这样，我该如何检测和治疗？其次，有没有办法让 vagrant 保持供应直到成功？我还没有找到这样做的记录 flag/setting，但感觉可能会有一个...
感谢您的帮助。
