This module will store the bucket used in the attachment database object, thus allowing you to retain read-only access to the filestore by simply overriding the bucket.

Setup details

Before installing this app, you should add several System Parameters (the most important of which is ir_attachment.location), OR set them through the config file as described later.

The in database System Parameters will act as overrides to the Config File versions.

Key	Example Value	Default Value
ir_attachment.location	s3
ir_attachment.location.host	minio:9000
ir_attachment.location.bucket	odoo
ir_attachment.location.region	us-west-1	us-west-1
ir_attachment.location.access_key	minio
ir_attachment.location.secret_key	minio_secret
ir_attachment.location.secure	1

Config File:

attachment_minio_host = minio:9000
attachment_minio_region = us-west-1
attachment_minio_access_key = minio
attachment_minio_secret_key = minio_secret
attachment_minio_bucket = odoo
attachment_minio_secure = False

In general, they should all be specified other than "region" (if you are not using AWS S3) and "secure" which should be set if the "host" needs to be accessed over SSL/TLS.

Install attachment_minio and during the installation base_attachment_object_storage should move your existing filestore attachment files into the database or object storage.

For example, you can run a shell command like the following to set the parameter:

env['ir.config_parameter'].set_param('ir_attachment.location', 's3')
# If already installed...
# env['ir.attachment'].force_storage()
env.cr.commit()

If attachment_minio is not already installed, you can then install it and the migration should be noted in the logs. Ensure that the timeouts are long enough that the migration can finish.
