Packer等待SSH

Question

我是Packer的新手。 我已经非常详细地研究了这个问题（上图）。 我目前正在尝试创建一个UBuntu 32位VM。 我在WIndows 10操作系统上运行Packer。 一旦安装完成并且VM重新启动，然后我提示使用GUI登录我的VM，而打包器仍然运行我的主机Windows说它正在等待SSH可用。 我怎样才能最好地使用ssh让Packer用来连接我的虚拟机。 这是我的json.template

PS是的我在来到这里并询问这个问题之前已经查看了模板。

Answer 1

实际上，我明白了。 这是将ssh_port设置为22，将ssh_address设置为我的vm地址，将ssh_skip_nat_mapping设置为true，然后将我的NIC卡从内部网络更改为hostonly然后进行配置的组合。

Answer 2

您覆盖Packers设置的网络，因此主机将无法访问来宾。 要解决此问题，请删除以下两行：

[ "modifyvm", "{{.Name}}", "--nic1", "intnet"], 
[ "modifyvm", "{{.Name}}","--nic2", "null"],
