自定义安装配置¶
本文将介绍如何在安装 NebulaGraph Operator 时自定义默认配置项。
配置项¶
在执行helm install [NAME] [CHART] [flags]
命令安装 Chart 时,可指定 Chart 配置。更多信息,请参考安装前自定义 Chart。
用户可以在 nebula-operator chart 配置文件中查看相关的配置选项。
或者执行命令helm show values nebula-operator/nebula-operator
查看可配置的选项,返回结果如下。
[root@master ~]$ helm show values nebula-operator/nebula-operator

示例¶
以下示例为在安装 NebulaGraph Operator 时,指定 NebulaGraph Operator 的 AdmissionWebhook 机制为开启状态(默认关闭 AdmissionWebhook):
helm install nebula-operator nebula-operator/nebula-operator --namespace=<nebula-operator-system> --set admissionWebhook.create=true
验证是否开启 AdmissionWebhook:
helm get values nebula-operator -n <nebula-operator-system>
示例输出:
USER-SUPPLIED VALUES:
admissionWebhook:
create: true
