I'm trying to add a local private key to the ssh-agent (docker image) during the build process.
Problem
I've run eval $(ssh-agent -s) and once docker runs the ssh-add /etc/ssh/id_rsa I receive the following error:
Could not open a connection to your authentication agent.
Goal: I need to clone a private git repo during to NPM install process. This local key will allow me to authenticate against the private repo.

The command '/bin/sh -c ssh-add /etc/ssh/id_rsa' returned a non-zero code: 2
The agent you run in Step 8 is dead by the time you are in Step 9. You need or perform all steps in one go for this to work.
RUN eval $(ssh-agent -s) && ssh-add /etc/ssh/id_rsa && git checkout .....
