How to configure multiple deploy keys for different private github repositories on the same computer without using ssh-agent

Let's say alice is a github.com user, with 2 or more private repositories repoN. For this example we'll work with just two repositories named repo1 and repo2

https://github.com/alice/repo1

https://github.com/alice/repo2

You need to be to pull from these repositories without entering a passwords probably on a server, or on multiple servers. You want to perform git pull origin master for example, and you want this to happen without asking for a password.

Jenkins Best Practices

	http://www.slideshare.net/andrewbayer/7-habits-of-highly-effective-jenkins-users
	Set up version control of job configurations
	Keep jobs simple! Don't put a ton of bash in each job. If a job needs to do something complex, put it in a script in GitHub and check it out as needed.
	Use templated builders to simplify common tasks
	Keep all scripts in version control - avoid running scripts that live on the Jenkins server filesystem
	Don't install unnecessary plugins - plugins are often written by third parties and can interact with each other in strange ways
	Use LDAP authentication if possible for traceability - avoid anonymous access
