创建 Octavia Loadbalancer 失败并显示 "Nova failed to build the instance due to: Invalid key_name provided"

Question

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且运行。我现在将 Octavia LBaaS 和运行添加到一个问题中。当我尝试在 horizon GUI 中创建负载平衡器时，失败并在 /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 keyname 中设置如下：

[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
...

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？

如有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，我们将不胜感激。

kolla-ansible版本：stable/stein

祝一切顺利，感谢阅读本文！

Answer 1

我想您已经与管理员用户创建了密钥对 "octavia_ssh_key"。

您可以尝试用 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  }')"

Answer 2

尝试使用 Octavia 用户创建密钥...绝对可以正常工作

创建 Octavia Loadbalancer 失败并显示 "Nova failed to build the instance due to: Invalid key_name provided"
