Notes on the Jenkins Deployment for Scalability around Pull Requests from GitHub.

Generate an id_rsa key, for example:

 ssh-keygen -t rsa -C "The access key for Jenkins slaves"

make sure the chmod's are right copy the public key

Important: This is all based on the key under /var/lib/jenkins/.ssh/ being with the following owner and access permissions:

  -rw-------.  1 jenkins jenkins 1675 Dec 21 21:20 id_rsa
  -rw-r--r--.  1 jenkins jenkins  419 Dec 21 21:20 id_rsa.pub

(see credentials below based on file)

copy the public key (id_rsa.pub) into

.ssh/authorized_keys

make sure the chmod is 600, as in:

-rw-------. 1 jenkins jenkins  831 Dec 21 23:05 authorized_keys

Note: Make sure in the copy you have one line for the copy. Sometimes, copying may break the key into multiple lines.

 Open the 22 ports to and from the two systems.

On your master machine go to Manage Jenkins > Manage Nodes.
