Passing ssh options to git clone

The recently released git 2.3 supports a new variable "GIT_SSH_COMMAND" which can be used to define a command WITH parameters.

GIT_SSH_COMMAND="ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no" git clone user@host

$GIT_SSH_COMMAND takes precedence over $GIT_SSH, and is interpreted by the shell, which allows additional arguments to be included.

Add them to your ~/.ssh/config:

Host host
    HostName host
    User user
    SshOption1 Value1
    SshOption2 Value2

The Host entry is what you’ll specify on the command line, and the HostName is the true hostname. They can be the same, or the Host entry can be an alias. The User entry is used if you do not specify user@ on the command line.

If you must configure this on the command line, set the GIT_SSH environment variable to point to a script with your options in it.
