GitLab can store some data in object storage
Enable the object store:
gitlab_rails['object_store']['enabled'] = true
gitlab_rails['object_store']['proxy_download'] = true
gitlab_rails['object_store']['connection'] = {
'provider' => 'AWS',
'aws_access_key_id' => '<AWS_ACCESS_KEY_ID',
'aws_secret_access_key' => '<AWS_SECRET_ACCESS_KEY>'
}
