To embed a git commit hash and git repository name (origin), please edit knife[:before_converge] in .chef/knife.rb like below.
knife[:before_converge] = %Q{
berks vendor vendor/cookbooks &&
echo "normal['syslog-provisioning']['git_hash'] = '$(git log -1 --pretty=format:%H)'" | tee cookbooks/base/attributes/syslog-provisioning_tmp.rb
echo "normal['syslog-provisioning']['git_repo'] = '$(git remote get-url --push origin)'" | tee -a cookbooks/base/attributes/syslog-provisioning_tmp.rb
}
Then, add 'include_recipe' to cookbooks/base/recipes/default.rb.
include_recipe 'syslog-provisioning'
cookbooks/base/attributes/syslog-provisioning_tmp.rb is not need to be version controlled. it can be ignored by .gitignore.
If your receipes dont't have base cookbooks, please find one corresponded to.
