Harbor在v1.6版本开始支持Helm Chart仓库功能，这样就可以利用 harbor 同时管理镜像和 helm charts 了，无需另外部署一套Helm Chart系统。在harbor中，chart仓库由chartmuseum以插件的方式提供，可以自己选择安装或者不安装。

ChartMuseum：提供了API管理非OCI规范的Helm Chart。在安装了ChartMuseum组件后，当用户使用“helm”命令向Harbor推送或拉取Chart时，Harbor的Core组件会首先收到请求，在校验后将请求转发给ChartMuseum进行Chart文件的读写。

1.修改配置文件
在absolute_url参使用ChartMuseum组件时，客户端获取到的Chart的index.yaml中包含的URL是否为绝对路径。在不配置该项时，ChartMuseum组件会返回相对路径，默认为disabled

[root@k8s-master2 harbor]# vi harbor.yml
chart:
  # Change the value of absolute_url to enabled can enable absolute url in chart
  absolute_url: enabled            absolute_url配置由disable更成enabled 
 

停止Harbor服务

[root@k8s-master2 harbor]# docker-compose stop
Stopping nginx             ... done
Stopping harbor-jobservice ... done
Stopping harbor-core       ... done
Stopping registry          ... done
Stopping registryctl       ... done
Stopping redis             ... done
Stopping harbor-portal     ... done
Stopping harbor-db         ... done
Stopping harbor-log        ... done

执行./prepare将新的配置注入到各个组件中。

[root@k8s-master2 harbor]# ./prepare

安装chartmuseum
在执行install.sh安装时，通过–with-chartmuseum参数安装chart插件，安装完后会自动启动Harbor

root@k8s-master2 harbor]# ./install.sh --with-trivy --with-chartmuseum
