Presetting the gpg-agent is necessary prio of git-crypt unlock

[ghoben]

Hi @pieterlange ,

I had troubles using your script since anytime I was using the git-crypt unlock, I was asked for the pass-phrase. So I found a way to preset the passphrase prior of calling git-crypt. Not sure if you are interested in the changes. I will not issue a pull requests until you want the changes integrated to your master. You can take a look at

ghoben/kube-backup branch 'origin/gpg-agent-fix'

. Also I added a job-cleanup script which can be called after ./entrypoint.sh in your cron-job without maintaining two jobs with different base images, as you have it in your

job-cleanup.yaml
