从 Harbor 2.8 开始，原来的 ChartMuseum 功能将不受支持，所有 Helm Charts 只能以 OCI Artifact 的形式来存储（这与 container image 类似 ）。
两者具体使用区别如下
Chart museum 的方式：
#下载：
helm repo add ako https://projects.registry.vmware.com/chartrepo/ako
helm pull ako/ako --version=1.10.3
#上传：
UI 支持直接上传 Charts 到 Harbor，或者使用 helm push [chart] [remote] [flags]
#管理：
Harbor 中有独立的 Helm Charts 页面，可以查看项目中所有 ChartsOCI Artifact 的方式：
#下载
# helm repo add 命令不受支持，每次 pull 需要指定完整的访问路径
helm pull oci://harbor.halfcoffee.com/common/ako --version=1.10.3
#上传
# UI 不支持直接上传 Charts，必须使用 helm push：
helm registry login harbor.halfcoffee.com --insecure
helm push ako-1.10.3.tgz oci://harbor.halfcoffee.com/common
#管理：
Harbor 中 Charts 与 Image 保存在同级目录下，没有单独的页面，可以通过搜索来过滤 Charts将 Harbor 升级到 2.8 后，需要做 Charts 的迁移，从原来的 Museum 的形式迁移到 OCI 格式，本文大致讲述下迁移方式。
Harbor 2.8 安装/升级（docker-compose）形式
准备 Harbor 的部署 yaml 文件，直接从模板拷贝，然后修改关键项目：
cp harbor.yml.tmpl harbor.yml
# 下面是我根据我的环境修改的几个配置：
https:
port: 443
certificate: /data/ssl/server/server.pem
private_key: /data/ssl/server/server-key.pem
data_volume: /data/harbor
database:
password: MTY4ZDdlZTczN2M1MGZiMzJlZTFiNWU4之后运行 install.sh 进行安装(升级)：

1、确定之前 Harbor 使用的存储路径，一般在 [data_volume]/chart_storage下，比如我就是 /data/harbor/chart_storage，可以先把这个文件夹备份一份。如果是将 Harbor 部署在 Kubernetes 中，则可能要参考此文章将 Charts 拷贝出来在运行下列容器。
2、部署容器并进行迁移，迁移过程实际上是从 chart_storage 读取 charts 的 tgz 文件，然后通过 OCI 规范推送到 Harbor
root@harbor# docker run -it --rm --network host -v /data/harbor/chart_storage:/chart_storage -v /data/ssl/rootca.pem:/usr/local/share/ca-certificates/harbor_ca.crt goharbor/migrate-chart:1.0.0 --hostname harbor.halfcoffee.com --password VMware1!

WARNING: Using --password via the CLI is insecure. Use --password-stdin.

Migrating chart ... [####################################] 100%
Migration is Done.注意：因为环境中 DNS 出了点问题，此处在 docker 所在节点上手动加了 hosts 记录，所以容器使用 host network，方便解析 Harbor 域名。
3、通过此文件查看是否有迁移失败的 charts：/data/harbor/chart_storage/migration_errors.txt
