Admin 部署架构
总体上来说Admin 部署架构分为以下几个部分
Admin 主进程包括服务发现元数据管理、可视化控制台、安全认证策略管控、其他定制化服务治理能力等组件。强依赖组件包括 Mysql 数据库、注册/配置/元数据中心可以是 Kubernetes、Nacos、Zookeeper 等可选依赖组件包括 Prometheus、Grafana、Zipkin 等
安装 Admin
Dubboctl 安装
Download
当前Dubboctl未正式发行可按以下方式进行尝试。 拉取Dubbo Admin并编译Dubboctl
git clone https://github.com/apache/dubbo-admin.git
cd dubbo-admin/cmd/dubboctl
go build -o dubboctl .将 dubboctl 放入可执行路径
ln -s dubbo-admin/cmd/dubboctl/dubboctl /usr/local/bin/dubboctlInstall
安装过程会依次
将用户自定义的配置profile以及set参数覆盖于默认profile得到最终的profile
