红帽全球峰会5.2. 转换为单堆栈集群网络
作为集群管理员，您可以将双栈集群网络转换为单堆栈集群网络。
重要
如果您最初将 IPv4 单堆栈集群网络转换为双栈集群，则只能转换回 IPv4 单堆栈集群，而不是 IPv6 单堆栈集群网络。相同限制适用于对 IPv6 单堆栈集群网络的转换（只能转换回 IPv6）。
先决条件
-
已安装 OpenShift CLI（
oc）。 -
使用具有
cluster-admin权限的用户登陆到集群。 - 集群使用 OVN-Kubernetes 网络插件。
- 集群节点具有 IPv6 地址。
- 您已启用了双栈网络。
流程
运行以下命令来编辑
networks.config.openshift.io自定义资源 (CR)：oc edit networks.config.openshift.io
$ oc edit networks.config.openshift.ioCopy to Clipboard Copied! Toggle word wrap Toggle overflow -
删除在 "Converting to a dual-stack cluster network " 步骤中添加到
cidr和hostPrefix参数中的 IPv4 或 IPv6 配置。
