congress.datasources.nova_driver module¶

Schema change history date: 2019-03-07 changes:

Added the created_at column to the servers table.

date: 2018-10-18 changes:

Added the servers.addresses table for server address information.

date: 2018-03-15 changes:

(incompatible) Removed the hosts table for OS hosts information because access to the information has been removed from the latest Nova API and client.

Added the hypervisors table for hypervisor information.

date: 2017-10-01 changes:

Added the tags table for server tags information.

servers_set_meta(args)¶

A wrapper for servers.set_meta().

‘execute[p(x)]’ doesn’t take optional args at the moment. Therefore, this function translates the positional ARGS to optional args and call the servers.set_meta() api. :param: <list> args: expected server ID and pairs of meta data in positional args such as:

{'positional': ['server_id', 'meta1', 'value1', 'meta2', 'value2']}

Usage:

execute[nova.servers_set_meta(svr_id, meta1, val1, meta2, val2) :-
    triggering_table(id)
