问题
I'm trying to setup automatic backups using a Jenkins build in Windows. The config is:
- Windows 7
- Jenkins 1.594
- putty tools beta 0.63
I'm running Jenkins as a service under a unprivileged 'jenkins' user. I have created a public/private key pair and uploaded it to the SSH server and I have validated that I'm able to login without informing the user password while running pageant with the private key loaded while logged in with the jenkins user.
The Jenkins build invokes a batch script which uses plink to run a postgres backup on the SSH server and after runs pscp to copy the backup locally. The issue is that, if I run the same script as the jenkins user via commandline everything works but when the script is invoked through Jenkins looks like it doesn't detect pageant is running. The jenkins user has an active session with pageant running.
The question is: how to make plink/pscp find the pageant instance?
