Problem

Using chef_vault_item in a recipe and testing via ChefSpec returns the following error:

Chef::Exceptions::InvalidDataBagPath:
       Data bag path '/var/folders/5d/46p9wf6976l9xptq3fwsrj9r0000gp/T/d20210228-64571-1lao3dr/data_bags' not found. Please create this directory.

Solution

1. Copy 'git-sync-fork' script code from gist
2. Create a file called 'git-sync-fork' in any 'bin' directory in your $PATH
3. Paste script into this new file 'git-sync-fork' and save
4. Make the file executable `chmod +x git-sync-fork`
5. Run the script inside your locally forked git repo

Example:

git-sync-fork upstream origin

Error

[Tue Jun 03 22:05:51 2014] [error] (110)Connection timed out: proxy: HTTP: attempt to connect to 127.0.0.1:3000 (127.0.0.1) failed

The problem is that the Apache proxy module, recognising that the service was unavailable, stopped redirecting requests to it for one minute.
