Uploads Migrate Rake Task

Migrate to Object Storage

After configuring the object storage for GitLab's uploads, you may use this task to migrate existing uploads from the local storage to the remote storage.

Note: All of the processing will be done in a background worker and requires no downtime.

All-in-one rake task

GitLab provides a wrapper rake task that migrates all uploaded files - avatars, logos, attachments, favicon, etc. - to object storage in one go. Under the hood, it invokes individual rake tasks to migrate files falling under each of this category one by one. The specifications of these individual rake tasks are described in the next section.

Omnibus Installation

gitlab-rake "gitlab:uploads:migrate:all"

Source Installation

sudo RAILS_ENV=production -u git -H bundle exec rake gitlab:uploads:migrate:all

Individual rake tasks

Note: If you already ran the rake task mentioned above, no need to run these individual rake tasks as that has been done automatically.

The rake task uses 3 parameters to find uploads to migrate.

Parameter	Type	Description
uploader_class	string	Type of the uploader to migrate from
model_class	string	Type of the model to migrate from
mount_point	string/symbol	Name of the model's column on which the uploader is mounted on.

Note: These parameters are mainly internal to GitLab's structure, you may want to refer to the task list instead below.

This task also accepts some environment variables which you can use to override certain values:

Variable	Type	Description
BATCH	integer	Specifies the size of the batch. Defaults to 200.

Migrate legacy uploads out of deprecated paths

Introduced in GitLab 12.3.

To migrate all uploads created by legacy uploaders, run:

bundle exec rake gitlab:uploads:legacy:migrate

Migrate from object storage to local storage

If you need to disable Object Storage for any reason, first you need to migrate your data out of Object Storage and back into your local storage.

Before proceeding, it is important to disable both direct_upload and background_upload under uploads settings in gitlab.rb

CAUTION: Warning: Extended downtime is required so no new files are created in object storage during the migration. A configuration setting will be added soon to allow migrating from object storage to local files with only a brief moment of downtime for configuration changes. See issue gitlab-org/gitlab#30979

All-in-one rake task

GitLab provides a wrapper rake task that migrates all uploaded files - avatars, logos, attachments, favicon, etc. - to local storage in one go. Under the hood, it invokes individual rake tasks to migrate files falling under each of this category one by one. For details on these rake tasks please refer to the section above, keeping in mind the task name in this case is gitlab:uploads:migrate_to_local.

Omnibus Installation

gitlab-rake "gitlab:uploads:migrate_to_local:all"

Source Installation

sudo RAILS_ENV=production -u git -H bundle exec rake gitlab:uploads:migrate_to_local:all

After this is done, you may disable Object Storage by undoing the changes described in the instructions to configure object storage
