Like Jeremy Saxton in https://statamic.com/forum/2744-git-and-spock I have my git repo set up above root on the production server, so like this

  • silbersee.git
  • public_html
    • [files for website]

In the post-receive hook I inserted the working tree

#!/bin/sh
GIT_WORK_TREE=/home/deb81801/domains/silbersee.com/public_html git checkout -f

But changes made using the CP give following log error

[2019-03-25 16:38:26] production.ERROR: Spock command exited unsuccessfully:
Command: git add /home/deb81801/domains/silbersee.com/public_html/site/content/pages/10.spock-test-page/en.index.md
Output: No output
Error:
fatal: Not a git repository (or any of the parent directories): .git

Where do I insert the GIT_WORK_TREE in Spocks settings so Spock knows where to commit?
