如何在不重新启动的情况下重新运行cloud-init [英] How to re-run cloud-init without reboot

问题描述

我正在使用openstack通过"nova boot"命令创建VM.我的映像启用了cloud-init.我传递了一个--user-data脚本，该脚本是bash shell格式，可在VM启动期间运行cloud-init.这一切都成功地发生了. 现在，我的用例是重新运行cloud-init以执行相同的用户数据脚本，而无需重新启动VM.我看到了/usr/bin/cloud-init选项，它们确实谈论了运行特定模块的问题，但是没有任何方法能够使它执行相同的用户数据脚本.如何实现呢?任何帮助，将不胜感激.

I am using openstack to create a VM using 'nova boot' command. My image is cloud-init enabled. I pass a --user-data script which is a bash shell format for cloud-init to run during VM boot up time. All this happens successfully. Now my use-case is to re-run cloud-init to execute the same user-data script without rebooting the VM. I saw /usr/bin/cloud-init options and they do talk about running specific modules but nothing is able to make it execute the same user-data script. How can this be achieved ? Any help would be appreciated.

推荐答案

要重置cloud-init，您需要执行rm -rf /var/lib/cloud/instances.

In order for cloud-init to reset, you need to execute rm -rf /var/lib/cloud/instances.

然后重新运行cloud-init start，它将再次运行完整的启动脚本过程.

Then re run the cloud-init start and it will run the full boot script process again.
