这是我的打包机Proxmox 中模板创建的配置

Packer 成功创建模板。克隆模板并启动 VM 后,我发现我的用户帐户被锁定了。
这是 /etc/shadow 文件
ubuntu:!$6$xyz$lrzkz89JCrvzOPr56aXfFFqGZpBReOx5ndDu9m5CwVFWjZsEIhvVm.I5B4zMxJdcdTyAvncwjKT.dWcD/ZHIo.:19269:0:99999:7:::
我登录虚拟机的唯一方法是使用私钥进行 SSH。控制台登录不起作用,因为密码被禁用。
看来lock_passwd: false
选项有问题。
知道什么地方出了问题吗?
更新1:
我/etc/cloud/cloud.cfg.d/99-installer.cfg
在启动之前检查了一台克隆机器。看起来一切正常。
然后我检查了一下/etc/cloud/cloud.cfg
,发现了这个
为什么lock_passwd 为 True如果我在 Packer 配置中将其设置为 false 呢?
更新2: 好的,我发现问题了。据我了解,用户名Ubuntu是默认的,并被默认设置锁定。我尝试使用其他用户名的模板,它可以正常工作。
