# Harbor upgrade and database migration guide
|
|
|
|
When upgrading your existing Harbor instance to a newer version, you may need to migrate the data in your database and the settings in `harbor.cfg`. Since the migration may alter the database schema and the settings of `harbor.cfg`, you should **always** back up your data before any migration.
|
|
|
|
**NOTE:**
|
|
|
|
- Again, you must back up your data before any data migration.
|
|
|
|
- This guide only covers the migration from v1.6.0 to current version, if you are upgrading from earlier versions please
|
|
refer to the migration guide in release branch to upgrade to v1.6.0 and follow this guide to do the migration to later version.
|
|
|
|
- From v1.6.0 on, Harbor will automatically try to do the migrate the DB schema when it starts, so if you are upgrading from v1.6.0
|
|
or above it's not necessary to call the migrator tool to migrate the schema.
|
|
|
|
- From v1.6.0 on, Harbor migrates DB from MariaDB to PostgreSQL, and combines Harbor, Notary and Clair DB into one.
|
|
|
|
- For the change in Database schema please refer to [change log](../tools/migration/db/changelog.md).
|
|
|
|
|
|
### Upgrading Harbor and migrating data
|
|
|
|
1. Log in to the host that Harbor runs on, stop and remove existing Harbor instance if it is still running:
|
|
```
|
|
cd harbor
|
|
docker-compose down
|
|
```
|
|
|
|
2. Back up Harbor's current files so that you can roll back to the current version when it is necessary.
|
|
```
|
|
mv harbor /my_backup_dir/harbor
|
|
```
|
|
Back up database (by default in diretory `/data/database`)
|
|
```
|
|
cp -r /data/database /my_backup_dir/
|
|
```
|
|
|
|
3. Get the latest Harbor release package from Github:
|
|
https://github.com/goharbor/harbor/releases
|
|
|
|
4. Before upgrading Harbor, perform migration first. The migration tool is delivered as a docker image, so you should pull the image from docker hub. Replace [tag] with the release version of Harbor (e.g. v1.5.0) in the below command:
|
|
```
|
|
docker pull goharbor/harbor-migrator:[tag]
|
|
```
|
|
|
|
5. Upgrade `harbor.cfg`.
|
|
**NOTE:** The ${harbor_cfg} will be overwritten, you must move it to your installation directory after migration.
|
|
```
|
|
docker run -it --rm -v ${harbor_cfg}:/harbor-migration/harbor-cfg/harbor.cfg goharbor/harbor-migrator:[tag] --cfg up
|
|
```
|
|
**NOTE:** The schema upgrade and data migration of Database is performed by core when Harbor starts, if the migration fails,
|
|
please check the log of core to debug.
|
|
|
|
6. Under the directory `./harbor`, run the `./install.sh` script to install the new Harbor instance. If you choose to install Harbor with components like Notary, Clair, and chartmuseum, refer to [Installation & Configuration Guide](../docs/installation_guide.md) for more information.
|
|
|
|
|
|
### Roll back from an upgrade
|
|
For any reason, if you want to roll back to the previous version of Harbor, follow the below steps:
|
|
|
|
**NOTE:** Roll back doesn't support upgrade across v1.5.0, like from v1.2.0 to v1.7.0. This is because Harbor changes DB to PostgreSQL from v1.7.0, the migrator cannot roll back data to MariaDB.
|
|
|
|
1. Stop and remove the current Harbor service if it is still running.
|
|
```
|
|
cd harbor
|
|
docker-compose down
|
|
```
|
|
|
|
2. Remove current Harbor instance.
|
|
```
|
|
rm -rf harbor
|
|
```
|
|
|
|
3. Restore the older version package of Harbor.
|
|
```sh
|
|
mv /my_backup_dir/harbor harbor
|
|
```
|
|
|
|
4. Restore database, copy the data files from backup directory to you data volume, by default `/data/database`.
|
|
|
|
5. Restart Harbor service using the previous configuration.
|
|
If previous version of Harbor was installed by a release build:
|
|
```sh
|
|
cd harbor
|
|
./install.sh
|
|
```
