* **ProjectAdmin**: When creating a new project, you will be assigned the "ProjectAdmin" role to the project. Besides read-write privileges, the "ProjectAdmin" also has some management privileges, such as adding and removing members.
* **SysAdmin**: "SysAdmin" has the most privileges. In addition to the privileges mentioned above, "SysAdmin" can also list all projects, set an ordinary user as administrator and delete users. The public project "library" is also owned by the administrator.
* **Anonymous**: When a user is not logged in, the user is considered as an "Anonymous" user. An anonymous user has no access to private projects and has read-only access to public projects.
A user can register himself/herself in Harbor in this mode. To disable user self-registration, refer to the [installation guide](installation_guide.md) for initial configuration, or disable this feature in [Administrator Options](#administrator-options). When self-registration is disabled, the system administrator can add users into Harbor.
When registering or adding a new user, the username and email must be unique in the Harbor system. The password must contain at least 8 characters with 1 lowercase letter, 1 uppercase letter and 1 numeric character.
When you forgot your password, you can follow the below steps to reset the password:
When an LDAP/AD user logs in by *username* and *password*, Harbor binds to the LDAP/AD server with the **"LDAP Search DN"** and **"LDAP Search Password"** described in [installation guide](installation_guide.md). If it succeeded, Harbor looks up the user under the LDAP entry **"LDAP Base DN"** including substree. The attribute (such as uid, cn) specified by **"LDAP UID"** is used to match a user with the *username*. If a match is found, the user's *password* is verified by a bind request to the LDAP/AD server.
Self-registration, changing password and resetting password are not supported under LDAP/AD authentication mode because the users are managed by LDAP or AD.
A project in Harbor contains all repositories of an application. No images can be pushed to Harbor before the project is created. RBAC is applied to a project. There are two types of projects in Harbor:
The function is project-oriented, and once the system administrator set a rule to one project, all repositories under the project will be replicated to the remote registry. Each repository will start a job to run. If the project does not exist on the remote registry, a new project will be created automatically, but if it already exists and the user configured in policy has no write privilege to it, the process will fail. When a new repository is pushed to this project or an existing repository is deleted from this project, the same operation will also be replicated to the destination. The member information will not be replicated.
There may be a bit of delay during replication according to the situation of the network. If replication job fails due to the network issue, the job will be re-scheduled a few minutes later.
Start replication by creating a rule. Click "Add Replication Rule" on the "Replication" tab, fill in the necessary fields, if there is no endpoint in the list, you need to create one, and then click "OK", a rule for this project will be created. If "Enable" is chosen, the project will be replicated to the remote immediately.
You can enable, disable or delete a rule in the rule list view. Only rules which are disabled can be edited and only rules which are disabled and have no running jobs can be deleted. If a rule is disabled, the running jobs under it will be stopped.
Entering a keyword in the search field at the top lists all matching projects and repositories. The search result includes both public and private repositories you have access to.
Administrator can add "Administrator" role to an ordinary user by click button on the left and select "Set as Administrator". To delete a user, select "Delete".
You can change authentication mode between **Database**(default) and **LDAP** before any user is added, when there is at least one user(besides admin) in Harbor, you cannot change the authentication mode.
When using LDAP mode, user's self-registration is disabled. The parameters of LDAP server must be filled in. For more information, refer to [User account](#user-account).
### Managing project creation
Use the **Project Creation** drop-down menu to set which users can create projects. Select **Everyone** to allow all users to create projects. Select **Admin Only** to allow only users with the Administrator role to create projects.
### Managing self-registration
You can manage whether a user can sign up for a new account. This option is not available if you use LDAP authentication.
### Managing verification of remote certificate
You can choose whether to verify remote endpoint's certification. You may need to disable certificate verification if the remote registry uses a self-signed or an untrusted certificate.
### Managing email settings
You can change Harbor's email settings, the mail server is used to send out responses to users who request to reset their password.
Harbor supports HTTP by default and Docker client tries to connect to Harbor using HTTPS first, so if you encounter an error as below when you pull or push images, you need to add '--insecure-registry' option to ```/etc/default/docker``` (ubuntu) or ```/etc/sysconfig/docker``` (centos) and restart Docker:
```Error response from daemon: Get https://myregistrydomain.com/v1/users/: dial tcp myregistrydomain.com:443 getsockopt: connection refused.```
If this private registry supports only HTTP or HTTPS with an unknown CA certificate, please add
`--insecure-registry myregistrydomain.com` to the daemon's start up arguments.
In the case of HTTPS, if you have access to the registry's CA certificate, simply place the CA certificate at /etc/docker/certs.d/myregistrydomain.com/ca.crt .
**Note: Replace "10.117.169.182" with the IP address or domain name of your Harbor node. You cannot pull a unsigned image if you enabled content trust.**
**CAUTION: If both tag A and tag B refer to the same image, after deleting tag A, B will also get deleted. if you enabled content trust, you need to use notary command line tool to delete the tag's signature before you delete an image.**
Next, delete the actual files of the repository using the registry's garbage collection(GC). Make sure that no one is pushing images or Harbor is not running at all before you perform a GC. If someone were pushing an image while GC is running, there is a risk that the image's layers will be mistakenly deleted which results in a corrupted image. So before running GC, a preferred approach is to stop Harbor first.
If you want to enable content trust to ensure that images are signed, please set two environment variables in the command line before pushing or pulling any image:
If you are using a self-signed cert, make sure to copy the CA cert into ```/etc/docker/certs.d/10.117.169.182``` and ```$HOME/.docker/tls/10.117.169.182:4443/```. When an image is signed, it is indicated in the Web UI.
**Note: Replace "10.117.169.182" with the IP address or domain name of your Harbor node. In order to use content trust, HTTPS must be enabled in Harbor.**
When an image is signed, it has a tick shown in UI; otherwise, a cross sign(X) is displayed instead.
**CAUTION: Clair is an optional component, please make sure you have already installed it in your Harbor instance before you go through this section.**
Static analysis of vulnerabilities is provided through open source project [Clair](https://github.com/coreos/clair). You can initiate scanning on a particular image, or on all images in Harbor. Additionally, you can also set a policy to scan all the images at a specified time everyday.
**Vulnerability metadata**
Clair depends on the vulnerability metadata to complete the analysis process. After the first initial installation, Clair will automatically start to update the metadata database from different vulnerability repositories. The updating process may take a while based on the data size and network connection. If the database has not been fully populated, there is a warning message at the footer of the repository datagrid view.
The 'database not fully ready' warning message is also displayed in the **'Vulnerability'** tab of **'Configuration'** section under **'Administration'** for your awareness.
Once the database is ready, an overall database updated timestamp will be shown in the **'Vulnerability'** tab of **'Configuration'** section under **'Administration'**. Click on the timestamp drop-down list, the timestamps of different namespaces are listed.
**Scanning an image**
Enter your project and locate the specified repository. Expand the tag list via clicking the arrow icon on the left side. For each tag there will be an 'Vulnerability' column to display vulnerability scanning status and related information. You can click on the vertical ellipsis to open a popup menu and then click on 'Scan' to start the vulnerability analysis process.
**NOTES: Only the users with 'Project Admin' role have the privilege to launch the analysis process.**
The analysis process may have the following status that are indicated in the 'Vulnerability' column:
* **Not Scanned:** The tag has never been scanned.
* **Queued:** The scanning task is scheduled but not executed yet.
* **Scanning:** The scanning process is in progress.
* **Error:** The scanning process failed to complete.
* **Complete:** The scanning process was successfully completed.
For the **'Not Scanned'** and **'Queued'** statuses, a text label with status information is shown. For the **'Scanning'**, a progress bar will be displayed.
If an error occurred, you can click on the **'View Log'** link to view the related logs.
If the process was successfully completed, a result bar is created. The width of the different colored sections indicates the percentage of features with vulnerabilities for a particular severity level.
* **Red:** **High** level of vulnerabilities
* **Orange:** **Medium** level of vulnerabilities
* **Yellow:** **Low** level of vulnerabilities
* **Grey:** **Unknown** level of vulnerabilities
* **Green:** **No** vulnerabilities
Move the cursor over the bar, a tooltip with summary report will be displayed. Besides showing the total number of features with vulnerabilities and the total number of features in the scanned image tag, the report also lists the counts of features with vulnerabilities of different severity levels. The completion time of the last analysis process is shown at the bottom of the tooltip.
Click on the tag name link, the detail page will be opened. Besides the information about the tag, all the vulnerabilities found in the last analysis process will be listed with the related information. You can order or filter the list by columns.
**NOTES: You can initiate the vulnerability analysis for a tag at anytime you want as long as the status is not 'Queued' or 'Scanning'.**
**Scanning all images**
In the **'Vulnerability'** tab of **'Configuration'** section under **'Administration'**, click on the **'SCAN NOW'** button to start the analysis process for all the existing images.
**NOTES: The scanning process is executed via multiple concurrent asynchronous tasks. There is no guarantee on the order of scanning or the returned results.**
To avoid frequently triggering the resource intensive scanning process, the availability of the button is restricted. It can be only triggered once in a predefined period. The next available time will be displayed besides the button.
**Scheduled Scan by Policy**
You can set policies to control the vulnerability analysis process. Currently, two options are available:
* **None:** No policy is selected.
* **Daily:** Policy is activated daily. It means an analysis job is scheduled to be executed at the specified time everyday. The scheduled job will scan all the images in Harbor.
**NOTES: Once the scheduled job is executed, the completion time of scanning all images will be updated accordingly. Please be aware that the completion time of the images may be different because the execution of analysis for each image may be carried out at different time.**
