我正在尝试通过kolla ansible安装OpenStack。具有3个控制平面节点和2个计算节点的集群已启动并运行。我现在添加了octavia LBaaS，遇到了一个问题。当我尝试在horizon GUI中创建负载均衡器时，失败了，在/var/log/kolla/octavia/octavia-worker.log中出现以下错误：
2019-10-22 14:39:35.969 24 INFO octavia.controller.queue.endpoint [-] Creating load balancer '8789f171-3a40-40dd-bcf3-f0ab02844eba'...

在/etc/octavia/octavia.conf中，keyname设置如下：
[controller_worker]
amp_ssh_key_name = octavia_ssh_key
amp_boot_network_list = 92df8748-2dfc-4270-8fef-d5163ef7ee56
amp_image_tag = amphora
amp_secgroup_list = a818a8c8-d8df-4886-a62a-dbcf29aa7e79
amp_flavor_id = 805ec684-b560-476e-938b-32b0fa4e6d16
...
openstack密钥对列表产生：
+-----------------+-------------------------------------------------+
| Name | Fingerprint |
+-----------------+-------------------------------------------------+
| user1 | aa:aa:aa:aa:85:2e:0d:b7:35:0a:c5:7e:3f:67:e5:a5 |
| user2 | aa:aa:aa:aa:fc:67:12:c6:20:3e:3b:bc:7a:75:35:cc |
| octavia_ssh_key | 28:b2:83:b1:e2:ee:c7:72:dc:bc:2e:3f:6e:ac:e2:61 |
+-----------------+-------------------------------------------------+
由于keyname在octavia.conf中设置为"octavia_ssh_key"，并且keypair在openstack中以该名称列出，我不确定是什么原因导致了错误。为什么nova无法找到正确的密钥对来构建ampora图像？
任何关于我还可以在哪里调试，或者还需要配置什么才能使octavia LBaaS工作的想法都将不胜感激。

祝你一切顺利，谢谢你读到这篇文章！

我想您已经与管理员用户创建了密钥对"octavia_ssh_key"。
你可以尝试用octavia用户重新创建这个；(
openstack keypair create octavia_ssh_key
--os-username octavia
--os-password "$(cat /etc/kolla/passwords.yml | grep octavia_keystone_password | awk '{ print $2 }')"

- 与密钥无关，可能是一些重写正在调用它们

# amp_ssh_key_name = octavia_ssh_key
重新启动octavia服务
尝试LB 的故障转移
openstack负载均衡器故障转移<loadbalancer_id>
LB应处于活动状态。
尝试使用Octavia用户创建密钥。。。它将工作得非常好
