Drain tasks from hosts running on specified IP addresses, so that you can safely perform maintenance on them. This works by addings the UNLIKE constraint for you.
Usage:
ber-kit drain --host http://marathon.example.com:8080 --urls 10.30.40.50,10.30.40.51
Once your migrations and rollovers are complete you need to cleanup and remove the temporary UNLIKE constraint.
You can also use this to rollback should your upgrade fail.
Usage:
ber-kit undrain --host http://marathon.example.com:8080 --urls 10.30.40.50,10.30.40.51
You can run the built-in tests by running:
nosetests /path/to/ber-kit
You can install this by running pip install nose.
