# Change any neutron agent admin state on any specified host.
|
|
#
|
|
# This script assumes that you have an openrc file in /root/openrc
|
|
# on the ansible host where you are running this from. It also
|
|
# requires that the neutron client be installed.

# Note: It is up to you, the user, to limit this with -l compute, -l control,
|
|
# etc otherwise all agents will be changed.
|
|
#
|
|
# Examples:
|
|
#
|
|
# Enable all L3 Agents on all compute nodes
|
|
# change-neutron-agent-state.yaml -e admin_state=up -e agent_type=L3 -l compute
|
|
#
|
|
# Disable all L3 Agents on all control nodes
|
|
# change-neutron-agent-state.yaml -e admin_state=down -e agent_type=L3 -l control
|
|
#
|
|
# Disable all Metadata Agents on all control nodes
|
|
# change-neutron-agent-state.yaml -e admin_state=down -e agent_type=Metadata -l control
|
|
#
|
|
# NOTE: Ovs is special because the shell eats the spaces
|
|
# Disable all OVS Agents on all compute nodes (this would probably be a bad idea to do)
|
|
# change-neutron-agent-state.yaml -e admin_state=down -e 'agent_type="Open vSwitch"' -l compute
