Did anything come of the investigation Jean-Christophe?
I've got some keys I need to provide Ansible in order to jump through bastion hosts. They differ from the credentials supplied to Ansible itself (the target host credential)
I'd normally add these keys to an ssh config and be done with it but within Jenkins I need to store these in the credential store. Without knowing the credential path for prior, there is no means of adding the path to the config hence the reliance on ssh-agent
If this could be achieved it would be excellent.
