 Harbor https://github.com/goharbor/harbor is to store docker images.
 
-We noticed the Harbor S3 storage backend is not robust. The following is a known issue:
+There are two ways to use SeaweedFS as a storage backend for Harbor:
+1. Use Harbor S3 storage backend with SeaweedFS S3.
+2. Use Harbor file storage backend with SeaweedFS FUSE mount.
 
-* Image Push Fails with "500 Internal Server Error" on S3 Storage
-https://docs.openshift.com/container-platform/3.10/install_config/registry/registry_known_issues.html#known-issue-s3-image-push-fails
-
-The better way to get around this is to simply use `weed mount`. Nothing special. Here is the Harbor config.yml
-```
-version: 0.1
-log:
-  fields:
-    service: registry
-storage:
-  cache:
-    blobdescriptor: inmemory
-  filesystem:
-    rootdirectory: /data
-http:
-  addr: :5000
-  headers:
-    X-Content-Type-Options: [nosniff]
-health:
-  storagedriver:
-    enabled: true
-    interval: 10s
-    threshold: 3
-
-```
-
-Suppose you mount the Seaweed to `<seaweedfs_mount_dir>`
-```
-weed mount -dir=<seaweedfs_mount_dir>
-```
-
-Start Harbor
-```
-docker run -p 5000:5000 --restart=always -v ./config.yml:/etc/docker/registry/config.yml -v <seaweedfs_mount_dir>/data:/data registry:2
-```
-
-
-Now you can use the harbor running in your `<ip>:5000`.
-
-```
-$ docker pull nginx:1.13.5-alpine
-$ docker tag nginx:1.13.5-alpine <ip>:5000/nginx:1.13.5-alpine
-$ docker push <ip>:5000/nginx:1.13.5-alpine
-```
+For better performance, use S3 API is recommended. This is because FUSE mount currently needs to save the file to a local folder, before uploading the file to SeaweedFS cluster.
