# Chart Migrating Tool
|
||
|
|
|
||
|
|
Harbor supports two different ways to storage the chart data.
|
||
|
|
|
||
|
|
1. stored in Harbor registry storage directly via OCI API.
|
||
|
|
2. stored in Harbor hosted chartmuseum backend via chartmuseam's API
|
||
|
|
|
||
|
|
There is an performance issue in chartmuseam. For example, on my 2 core 8G memory test environment, to get 10000 charts infomation needs about 10s to return, In 50000 charts situation, It will cause a timeout error.
|
||
|
|
|
||
|
|
After version 2.0, Harbor becomes to the OCI registry. So It can storage chart content directly without chartmuseum.
|
||
|
|
|
||
|
|
This tool used to migrate the legacy helm charts stored in the chartmuseum backend to Harbor OCI registry backend.
|
||
|
|
|
||
|
|
On test environment( 2 core 8G memory), using this tool to migrate 10000 charts needs about 2~3 hours
|
||
|
|
|
||
|
|
## Usages
|
||
|
|
|
||
|
|
Compile the chart with command
|
||
|
|
|
||
|
|
``` sh
|
||
|
|
docker build -t goharbor/migrate-chart:0.1.0 .
|
||

```
|

Migrate charts run command below:

docker run -it --rm -v {{your_chart_data_location}}:/chart_storage -v {{harbor_ca_cert_location}}:/usr/local/share/ca-certificates/harbor_ca.crt goharbor/migrate-chart:0.1.0 --hostname {{harbor_hostname}} --password {{harbor_admin_password}}
