"Add correct host key in known_hosts" / multiple ssh host keys by host name?

Question

I’m having an error that maybe some of you have faced between Jenkins and GIT.

The JENKINS machine connects with a GIT machine, but at the time of PUSH if it connects with another machine (replica) will give an error! However I am doing a temporary solution all x have to remove the know_hosts file manually by running a "rm -Rf"
