​回顾 Dubbo 服务治理体系的总体架构，Admin 是服务治理控制面中的一个核心组件，负责微服务集群的服务治理、可视化展示等。

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/dubboctl

Install

安装过程会依次：

1. 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

# default profile
apiVersion: dubbo.apache.org/v1alpha1
kind: DubboOperator
metadata:namespace: dubbo-system
spec:profile: defaultnamespace: dubbo-systemcomponentsMeta:admin:enabled: truegrafana:enabled: truerepoURL: https://grafana.github.io/helm-chartsversion: 6.52.4nacos:enabled: truezookeeper:enabled: truerepoURL: https://charts.bitnami.com/bitnamiversion: 11.1.6prometheus:enabled: truerepoURL: https://prometheus-community.github.io/helm-chartsversion: 20.0.2skywalking:enabled: truerepoURL: https://apache.jfrog.io/artifactory/skywalking-helmversion: 4.3.0zipkin:enabled: truerepoURL: https://openzipkin.github.io/zipkinversion: 0.3.0

建议使用自定义profile进行配置，在componentsMeta中开启或关闭组件，在components下配置各组件。其中components下各组件的配置值都是helm chart的values，各组件的具体配置请参考： Grafana: https://github.com/grafana/helm-charts/blob/main/charts/grafana/README.md Zookeeper: https://github.com/bitnami/charts/tree/main/bitnami/zookeeper/#installing-the-chart Prometheus: https://github.com/prometheus-community/helm-charts/tree/main/charts Skywalking: https://github.com/apache/skywalking-kubernetes/blob/master/chart/skywalking/README.md Zipkin: https://github.com/Financial-Times/zipkin-helm

# customization profile
apiVersion: dubbo.apache.org/v1alpha1
kind: DubboOperator
metadata:namespace: dubbo-system
spec:profile: defaultnamespace: dubbo-systemcomponentsMeta:admin:enabled: truegrafana:enabled: trueversion: 6.31.0prometheus:enabled: falsecomponents:admin:replicas: 3grafana:testFramework:enabled: false

1. 根据profile拉取所需组件并生成manifest，目前Admin，Nacos已在本地，无需拉取；Grafana，Zookeeper，Prometheus，Skywalking，Zipkin将从官方chart库拉取，具体地址和版本可见上方default profile
2. 将manifest应用于k8s集群

dubboctl manifest install # 使用默认 manifests 安装# ordubboctl manifest generate | kubectl apply -f -

dubboctl install --set spec.components.admin.replicas=2 # 设置组件的配置

dubboctl install --set spec.componentsMeta.admin.enabled=true, spec.componentsMeta.grafana.enabled=false
# 开启或关闭组件

dubboctl install --set spec.componentsMeta.grafana.repoURL=https://grafana.github.io/helm-charts, spec.componentsMeta.grafana.version=6.31.0
# 设置需远程拉取组件的仓库地址与版本

检查安装效果

kubectl get pod -n dubbo-system

打开 Admin 控制台

kubectl port-forward svc/dubbo-admin -n dubbo-system 38080:38080

VM 安装

Download

下载 Dubbo Admin 发行版本

curl -L https://dubbo.apache.org/installer.sh | VERSION=0.1.0 sh -
# Admin 要组织好发行版本

将 dubboctl 放入可执行路径

ln -s dubbo-admin-0.1.0/bin/dubbo-admin /usr/local/bin/dubbo-admin

Run

dubbo-admin run -f override-configuration.yml
