A10 Networks LBaaS Driver
Installation info:
To use this driver, you must:
- Install the a10-neutron-lbaas module. (E.g.: 'pip install a10-neutron-lbaas')
- Create a driver config file, a sample of which is given below.
- Enable it in neutron.conf
- Restart neutron-server
Third-party CI info:
Contact info for any problems is: a10-openstack-ci at a10networks dot com
Or contact Doug Wiegley directly (IRC: dougwig)
Configuration file:
Create a configuration file with a list of A10 appliances, similar to the
file below, located at:
/etc/neutron/services/loadbalancer/a10networks/config.py
Or you can override that directory by setting the environment
variable A10_CONFIG_DIR.
Example config file:
devices = {
"ax1": {
"name": "ax1",
"host": "10.10.100.20",
"port": 443,
"protocol": "https",
"username": "admin",
"password": "a10",
"status": True,
"autosnat": False,
"api_version": "2.1",
"v_method": "LSI",
"max_instance": 5000,
"use_float": False,
"method": "hash"
},
"ax4": {
"host": "10.10.100.23",
"username": "admin",
"password": "a10",
},
}
