Project Harbor is an enterprise-class registry server, which extends the open source Docker Registry server by adding the functionality usually required by an enterprise, such as security, control, and management. Harbor is primarily designed to be a private registry - providing the needed security and control that enterprises require. It also helps minimize bandwidth usage, which is helpful to both improve productivity (local network access) as well as performance (for those with poor internet connectivity).
|
||||
|
||||
### Features
|
||||
* **Role Based Access Control**: Users and docker repositories are organized via "projects", a user can have different permission for images under a namespace.
|
||||
* **Graphical user portal**: User can easily browse, search docker repositories, manage projects/namespaces.

|
||||
* **AD/LDAP support**: Harbor integrates with existing enterprise AD/LDAP for user authentication and management.
|
||||
* **Auditing**: All the operations to the repositories are tracked.
|
||||
* **Internationalization**: Already Localized for English, Chinese and German. More languages can be added.

#### Configuring Harbor with HTTPS Access
|
||||
Harbor does not ship with any certificates, and, by default, uses HTTP to serve requests. While this makes it relatively simple to set-up and run - especially for a development or testing environment - it is **not** recommended for a production environment. To enable HTTPS, please refer to [Configuring Harbor with HTTPS Access](configure_https.md)
|
||||
|
||||
#### Configuring Harbor as a local registry mirror
|
||||
The Harbor runs as a local private registry by default, it can be easily configured to run as a local registry mirror, which can keep most of the redundant image fetch traffic on your local network. You just need to edit `config/registry/config.yml` after execute `./prepare`, and append a `proxy` section as follows:
|
||||
|
||||
```
|
||||
proxy:
|
||||
remoteurl: https://registry-1.docker.io
|
||||
```
|
||||
In order to access private images on the Docker Hub, a username and password can be supplied:
|
||||
|
||||
```
|
||||
proxy:
|
||||
remoteurl: https://registry-1.docker.io
|
||||
username: [username]
|
||||
password: [password]
|
||||
```
|
||||
You will need to pass the `--registry-mirror` option to your Docker daemon on startup:
|
||||
|
||||
```
|
||||
docker --registry-mirror=https://<my-docker-mirror-host> daemon
|
||||
```
|
||||
For example, if your mirror is serving on `http:/reg.yourdomain.com`, you would run:
|
||||
|
||||
```
|
||||
docker --registry-mirror=https://reg.yourdomain.com daemon
|
||||
```
|
||||

||||

|
||||
|
||||
#### Configuring storage backend
|
||||
|
||||
By default, the Harbor store images on your local filesystem. In production environment, you may consider using higher available storage backend instead of the local filesystem, like S3, Openstack Swift, Ceph, etc. Fortunately, the Registry supports multiple storage backend, refer to the [Registry Configuration Reference](https://docs.docker.com/registry/configuration/) for detail information. All you need to do is update the section of `storage`, and fill in the fields according to your specied backend. For example, if you use Openstack Swift as your storage backend, the file may look like this:

In addition, Harbor users `rsyslog` to collect the logs of each container. By default, these log files are stored in the directory `/var/log/harbor/` on the target host.
