The documentation here: https://circleci.com/docs/2.0/add-ssh-key/ on adding SSH keys is really not sufficient.
When I add an SSH key in this method, how can I access it within the container? My usecase is the following:
I have a multistage dockerfile which builds a container. The builder requires access to a private repo, so a private SSH key is required as a build argument.
It appears that the SSH key added to the circleci build container is not in ~/.ssh, as you would expect, so is it set as an environment variable? If so, what is the label for this environment variable?
