Google Cloud Datastore storage plugin for errbot

About

Errbot is a python chatbot, this storage plugin allows you to use it with Google Cloud Datastore as a persistent storage.

Installation

1. Configure and get the private key json of a service account for Google Cloud Datastore from the Cloud Console of your project.
2. Save the file in errbot's data directory under the name servacc.json. (Or another destination but you need to override it in the config below)
3. First you need to clone this repository somewhere, for example:

mkdir /home/gbin/err-storage
cd /home/gbin/err-storage
git clone https://github.com/errbotio/err-storage-gcd

4. Then you need to add this section to your config.py, following the previous example:

BOT_EXTRA_STORAGE_PLUGINS_DIR='/home/gbin/err-storage'
STORAGE = 'GoogleCloudDatastore'
STORAGE_CONFIG = {
   'project': 'foo-bar-123', # Your google cloud project id
   'accountfile': '/tmp/account-12432.json', # path to your credentials in json format for a service account. (defaults to BOT_DATA_DIR/servacc.json)
   'namespace': 'Errbot'  # it will default to Errbot if you don't specify it
   }

Start your bot in text mode: errbot -T to give it a shot.

If you want to migrate from the local storage to GCD, you should be able to backup your data (with STORAGE commented) then restore it back with STORAGE uncommented.

Data format

It will create a type of entity per plugin in a namespace called "Errbot" by default. The only entry per entity will by named value and will be a serialized json of the object the plugin tried to store.
