根据https://blog.51cto.com/penguintux/2539670安装openstack
kolla默认使用flat作外网，现调整eth1为trunk，重新配置neutron

编辑ml2_conf.ini

cat <<EOF>> /etc/kolla/config/neutron/ml2_conf.ini 
[ml2_type_vlan]
network_vlan_ranges = physnet1:10:1000
# 也可以不指定vlan的范围
# network_vlan_ranges = physnet1:10:1000,physnet2

[ml2_type_flat]
flat_networks = 
EOF

重新配置neutron

kolla-ansible \
   -i kolla-ansible/ansible/inventory/all-in-one  \
   reconfigure \
   --tags neutron

创建provider网络作为外网

• --provider-segment：vlan id

openstack network create  \
  --provider-network-type vlan   \
  --provider-physical-network physnet1 \
  --provider-segment 100 \
  --external \
  --project service \
  public
