[bitnami/odoo] Ability to extend python packages without custom image build

[tbscode]

Name and Version

bitnami/odoo

What is the problem this feature will solve?

There is no good way to add extra add-ons that require additional python packages.
Add-ons in /bitnami/odoo/addons can persist and it can be utilized to install custom add-ons without modifying the base image.

And I can install python requirement to the running container using source /opt/bitnami/odoo/venv/bin/activate && pip3 install -r /requirements.txt

But the helm chart utilizes the venv at /opt/bitnami/odoo/venv/ this is not part of any volume claim, therefore re-sets on every container start-up.

What is the feature you are proposing to solve the problem?

A good-way to use the odoo helm chart with custom modules that require additional python packages.

I could Imagine having a separate virtual environment inside the odoo data volume claim that is linked to the /opt/bitnami/odoo/venv/ e.g.: /bitnami/odoo/venv that users can install extra pip packages in.

What alternatives have you considered?

Installing them every time at start-up using the initContainer.

Please correct me if there already is another way to achieve this? 🙏🏻

Hi!

Thank you so much for the feedback! I agree that the UX could be improved with, for example, allowing via values.yaml to introduce a set of python packages and have the chart render the init container that installs the plugin. I have my concerns on persisting the full packages section of the virtual environment as it could potentially break security upgrades. However, auto-generating the pip instal init container could be a good first step. Thoughts?

I like the idea, sounds like it would be a valid solution.

Personally not entirely sure how such a setup would look-like, do you do something similar in other charts.

We use init containers in other charts, but we did not cover this use case. Could you try first creating an init container that covers the use case? Then, using that as a base, we could add improve the chart.
