odoo-s3 uses boto3 to talk to Amazon S3. You will need to install it on the host running Odoo.

Make sure you set the ODOO_ADDONS_PATH variable to the directory where you install your custom Odoo modules.

pip install boto3
cd $ODOO_ADDONS_PATH
git clone https://github.com/marclijour/odoo-s3

This module is compatible with Odoo 11 and Python 3. For older versions, you can refer to the original source code (see credits below).

In order to use odoo-s3 you will need to switch to "Developer mode" and define a new system parameter as follows:

• without encryption:

ir_attachment.location  --->  s3://<Your-AWS-Access-Key-ID>:<Your-AWS-Secret-Key>@<Your-S3-Bucket-name>

• with server-side encryption (only AES256, since aws:kms is not supported in boto3):

ir_attachment.location  --->  s3://<Your-AWS-Access-Key-ID>:<Your-AWS-Secret-Key>@<Your-S3-Bucket-name>+SSE

This code is forked from brolycjw's repository who ported the original code from tvanesse to Odoo v10.0, and moving from boto to boto3.
