Docker中的共享卷通过Vagrant

Question

我有一个Vagrant虚拟框,它托管一个Docker容器.主机有一个文件夹,需要在vm和容器中访问:

Host: /host/path => VM: /vagrant/path => Container: /docker/path

背景:/host/path/保存项目的开发文件,这些文件在容器级别可用,以确保在进行更改时自动重新加载.

组态

流浪汉:

Vagrant.configure("2") do |config|
  config.vm.synced_folder "/host/path", "/vagrant/path"
end

泊坞窗:

docker run -name mycontainer -d -v /vagrant/path:/docker/path my/image

问题

此配置有效,直到我重新加载vm.例如,当我重新启动计算机并启动vm时vagrant up,docker容器只识别一个空文件夹/docker/path.我想这可能是一些时间或顺序问题./vagrant/path不是空的并且具有正确的内容.

我的解决方法是在每次重启vm后重新加载容器:

docker rm mycontainer 
docker kill mycontainer 
docker run -name mycontainer -d -v /vagrant/path:/docker/path my/image

那感觉不对.有任何想法吗？

Answer 1

我也有同样的问题。发布的解决方案不符合我的要求。

这是我的解决方案。如果您运行多个容器，请迭代中的 cids /var/lib/vagrant/cids/中的 cids

第一个脚本禁用 docker-deamon 容器在启动时自动启动。仅当第二个脚本未运行时，才通过其 CID 启动容器。

这适用于初始vagrant up和后续vagrant [ up | 重新加载] --规定
