Spring Cloud Config Server通过SSH连接Bitbucket报认证方法耗尽错误

问题背景 #

我正尝试创建Spring Cloud Config Server，通过SSH URI连接Bitbucket的Git仓库，遵循Spring Cloud Config规范，但遇到了认证失败的错误。

已执行的操作 #

1. 生成密钥对 #

使用以下命令生成RSA密钥对：

ssh-keygen -m PEM -t rsa -b 4096 -C "sweta"

2. 获取known_hosts条目 #

执行命令连接主机以生成known_hosts条目：

ssh webprod-cvs2.test.com

命令输出：

The authenticity of host 'webprod-cvs2.test.com (161.134.126.61)' can't be established.
ECDSA key fingerprint is SHA256:rOc67c4dj1nBlEnNJvB5e6u2TkcJo8k7X1VJCWk.
This key is not known by any other names

最终known_hosts中的条目：

webprod-cvs2.test.com ecdsa-sha2-nistp256 AAAAE2VjZHNhLXAAAIbmlzdHAyNTYAAABBBOJeugo5WQ2UlUBDH7UWJUOSCp0f20thcUw8G8ZoKP54OBIgsBXeb8x5PxTq86jOmY+K4yYQFHGVdH8Vmz6HsgM=
