# Import Vulnerability Data to an Offline Harbor instance
Harbor has integrated with Clair to scan vulnerabilities in images. When Harbor is installed in an environment without internet connection, Clair cannot fetch data from the public vulnerability database. Under this circumstance, Harbor administrator needs to manually update the Clair database.
If Harbor is installed in an environment without an internet connection, Clair cannot fetch data from the public vulnerability database. In this case, the Harbor administrator must update the Clair database manually.
This document provides step-by-step instructions on updating Clair vulnerability database in Harbor.
## Preparation
**NOTE:** Harbor does not ship with any vulnerability data. For this reason, if Harbor cannot connect to Internet, the administrator must manually import vulnerability data to Harbor by using instructions given in this document.
- You have an instance of Clair that has an internet connection. If you have another instance of Harbor that has internet access, this also works.
- Check whether your Clair instance has already updated its vulnerability database to the latest version.
### Preparation
A. You need to install an instance of Clair with internet connection. If you have another instance of Harbor with internet access, it also works.
B. Check whether your Clair instance has already updated the vulnerability database to the latest version. If it has not, wait for Clair to get the data from public endpoints.
- Use command `docker ps` to find out the container id of Clair.
- Run command `docker logs container_id` to check the log of the Clair container. If you are using Harbor you can find the latest Clair log under /var/log/harbor/2017-xx-xx/clair.log
- Look for logs that look like the below:
1. Use `docker ps` to find out the container ID of the Clair service.
1. Run `docker logs <container_id>` to check the log of the Clair container. If you are using Harbor you can find the latest Clair logs under `/var/log/harbor/2017-xx-xx/clair.log`.
1. Look for logs that look like the following:

```
- The phrase "finished fetching" indicates that Clair has finished a round of vulnerability update from an endpoint. Please make sure all five endpoints (rhel, alpine, oracle, debian, ubuntu) are updated correctly.
The phrase `finished fetching` indicates that Clair has finished a round of vulnerability updates from an endpoint. Make sure all of the `rhel`, `alpine`, `oracle`, `debian`, and `ubuntu` endpoints are updated correctly. If they have not, wait for Clair to get the data.
## Harbor version < 1.6
## Dump Vulnerability Data
If you're using a version of Harbor prior to 1.6, you can access the correct instructions for your version using the following URL.
https://github.com/goharbor/harbor/blob/v\<VERSION NUMBER>/docs/import_vulnerability_data.md
1. Log in to the host, that is connected to Internet, on which the Postgres Clair database is running.
1. Dump Clair's vulnerability database by running the following commands.
## Harbor version >= 1.6
**NOTE**: The container name `clair-db` is a placeholder for the database container used by the internet-connected instance of Clair.
Databased were consolidated in version 1.6 which moved the clair database to the harbor-db container and removed the clair-db container.
```
$ docker exec clair-db /bin/sh -c "pg_dump -U postgres -a -t feature -t keyvalue -t namespace -t schema_migrations -t vulnerability -t vulnerability_fixedin_feature" > vulnerability.sql
```
```
$ docker exec clair-db /bin/sh -c "pg_dump -U postgres -c -s" > clear.sql
```
### Dumping vulnerability data
The files `vulnerability.sql` and `clear.sql` are generated.
- Log in to the host (that is connected to Internet) where Clair database (Postgres) is running.
- Dump Clair's vulnerability database by the following commands, two files (`vulnerability.sql` and `clear.sql`) are generated:
## Back Up the Harbor Clair Database
_NOTE: The container name 'clair-db' is a placeholder for the db container used by the internet connected instance of clair_
```
$ docker exec clair-db /bin/sh -c "pg_dump -U postgres -a -t feature -t keyvalue -t namespace -t schema_migrations -t vulnerability -t vulnerability_fixedin_feature" > vulnerability.sql
$ docker exec clair-db /bin/sh -c "pg_dump -U postgres -c -s" > clear.sql
```
### Back up Harbor's Clair database
Before importing the data, it is strongly recommended to back up the Clair database in Harbor.
```
$ docker exec harbor-db /bin/sh -c "pg_dump -U postgres -c" > all.sql
```
### Update Harbor's Clair database
Copy the `vulnerability.sql` and `clear.sql` to the host where Harbor is running on. Run the below commands to import the data to Harbor's Clair database:
## Update the Harbor Clair Database
```
$ docker exec -i harbor-db psql -U postgres < clear.sql
$ docker exec -i harbor-db psql -U postgres < vulnerability.sql
```
1. Copy the `vulnerability.sql` and `clear.sql` files to the host on which Harbor is running.
1. Run the following commands to import the data to the Harbor Clair database:
### Rescanning images
After importing the data, trigger the scanning process in the administrator's web UI: **Administration**->**Configuration**->**Vulnerability**->**SCAN NOW**. Harbor reflects the new changes after the scanning is completed. (Otherwise the summary of the image vulnerabilities will not be displayed correctly.)
```
$ docker exec -i harbor-db psql -U postgres < clear.sql
```
```
$ docker exec -i harbor-db psql -U postgres < vulnerability.sql
```
## Rescan the Images
After importing the data, trigger the scanning process in the Harbor interface. For information about running a scan, see [Scan All Images](scan_all_images.md).
