PowerFlex： 以金鑰為基礎的 SSH 驗證失敗，並傳回「invalid privatekey」

使用 Gateway 的 PowerFlex 部署將會失敗，並在閘道上出現以下錯誤。

請確定私密金鑰為 PEM 格式。
比如：

# file /root/.ssh/id_rsa
/root/.ssh/id_rsa: PEM RSA private key



# cat /root/.ssh/id_rsa
-----BEGIN RSA PRIVATE KEY-----
-----END RSA PRIVATE KEY-----

如果檔案類型不同，請將其轉換為 PEM 檔案或使用命令建立 ssh 金鑰。 

ssh-keygen -m pem -t rsa
