How to run git pull and bypass SSH passphrase prompt in user startup script?

This is on Ubuntu, I have a user startup shell script that runs every time the instance boots (EC2 via --user-data-file argument). I want to have the instance do a git pull from a specific branch every time it boots. The problem is when I do a git pull, there is a SSH key passphrase prompt and I am not sure what the best way is to automatically enter the password in a shell script.
