When you try to connect to SSH server, you might have seen the following prompt.
$ ssh user@remote-server
If you are connecting to the remote server for the first time, you will a prompt confirming the authenticity of the host.
However, this will be problematic in case of CI/CD servers, where you need to connect to the remote server without any prompt.
To do that, you can use the following command.
$ ssh -o StrictHostKeyChecking=no user@remote-server
