Kubernetes集群的Pod使用Openstack Cinder作为后端存储，需要部署cinder-csi-plugin

https://github.com/kubernetes/cloud-provider-openstack

连不上 Keystone: 为部分 Pod 添加自定义域名解析

Keystone url用了域名，需要在/etc/hosts添加域名解析

以下仅用于举例说明如何为 Pod 添加自定义域名解析

如果有部分 Pod 对特定的域名解析有依赖，在不希望配置 dns 解析的情况下，可以使用 K8S 提供的 hostAliases 来为部分工作负载添加 hosts:

spec:
  hostAliases:
  - hostnames: [ "harbor.example.com" ]
    ip: "10.10.10.10"
复制代码

添加后在容器内可以看到 hosts 被添加到了 /etc/hosts 中:

$ cat /etc/hosts
...
# Entries added by HostAliases.
10.10.10.10    harboar.example.com
复制代码
