ssh 连接容器实验室失败

Question

场景一：

1. 使用 ansible ssh 到 csr1000v 路由器。
2. Jenkins 返回 ssh 连接失败。

场景2：

1. 部署容器csr1000v后，我手动ssh进入其中并保存指纹。
2. 使用ansible ssh 进入csr1000v
3. Jenkins 返回成功。

我不明白为什么我必须先手动 ssh 到 csr1000v 路由器才能允许 ansible 成功 ssh 到路由器进行配置。有什么解决方案可以解决这个问题吗？需要解决这个问题以实现自动化。

ansible.cfg

[defaults]
inventory = hosts
gathering = explicit
host_key_checking = False
retry_file_enabled = False

这是我添加的解决问题的行...
