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.
