是新注册的账户，Vultr 的账户显示是通过了的：
Congratulations! You have been admitted into the Free Tier Program!
You were approved for early access to the Free Tier Program.
Your Free Tier starts on 2023-12-21 and will end on 2024-12-21.
During that year, you will be able to launch a Free Tier instance. You can only have 1 free instance running at a time. If you shut down the instance you can relaunch it up to twice per month.
The free instance can be deployed on the instance deploy page under:
Cloud Compute > Regular > Free Instance
部署的时候，也没找到有 Free 的实例啊。懵逼中。
