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正在运行。 我现在添加了 Octavia LBaaS 并遇到了问题。 当我尝试在地平线 GUI 中创建负载平衡器时，这失败了，并在 /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 键名是这样设置的：
[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
...
一个 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 |
+-----------------+-------------------------------------------------+
由于键名在 octavia.conf 中设置为“octavia_ssh_key”并且密钥对在 openstack 中列在该名称下，我不确定是什么导致了错误。为什么 nova 无法找到正确的密钥对来构建 ampora 镜像？
任何关于我还可以调试或还需要配置什么以使 Octavia LBaaS 正常工作的想法都将不胜感激。

一切顺利，感谢您阅读本文！

我想你已经用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 }')"

重启octavia服务
尝试 LB 的故障转移
openstack 负载均衡器故障转移
LB 应该处于活动状态。
尝试使用 Octavia 用户创建密钥......它绝对可以正常工作
