如何将 SSH 密钥添加到云实例？

我尝试手动添加密钥，但就是无法连接。以下是我尝试的方法：

thufir@mordor:~$ 
thufir@mordor:~$ gcloud compute config-ssh
WARNING: The private SSH key file for Google Compute Engine does not exist.
WARNING: You do not have an SSH key for Google Compute Engine.
WARNING: [/usr/bin/ssh-keygen] will be executed to generate a key.
Generating public/private rsa key pair.
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /home/thufir/.ssh/google_compute_engine.
Your public key has been saved in /home/thufir/.ssh/google_compute_engine.pub.
The key fingerprint is:
SHA256:ioreurewiopruweoiprwe thufir@mordor
The key's randomart image is:
+---[RSA 2048]----+
.......
|                 |
|                 |
+----[SHA256]-----+

Updated [https://www.googleapis.com/compute/v1/projects/<project>].
You should now be able to use ssh/scp with your instances.
For example, try running:

  $ ssh <instance>.<location>.<project>

thufir@mordor:~$ 
thufir@mordor:~$ ssh <instance>.<location>.<project>
The authenticity of host 'compute.<####> (<ip address>)' can't be established.
ECDSA key fingerprint is SHA256:<fingerprint?>.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'compute.<####>' (ECDSA) to the list of known hosts.

答案1

答案可能有点太晚了，但这就是答案

ssh-keygen -t rsa -f ~/.ssh/google_compute_engine -C <service-account>

然后

gcloud compute ssh <service-account> --command="bash xxxxxx"

答案2

您无需手动将其添加到用户文件夹中。每次您尝试登录虚拟机时，Google Cloud 都会自动添加它。要永久添加虚拟机实例中的 SSH 密钥，您可以在菜单中的元数据中添加公钥。这里解释了逐步的步骤过程。
