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",

"method": "hash"
|
||||
},

"ax4": {
|
