Multiple trytond services

Support User

For many Docker seems to be the preferred way of running trytond in production
(Configure Tryton server 5 (good practices or advices))
I don’t know Docker, I’v read a few articles on running Docker in production, it’s not that simple.

So we might start running trytond as a regular service on a vm. And maybe later using Docker.

We would also like to run several trytond services. Each running with it’s own database and log file.
I managed to run 2 services on one vm and it works. (see below)

Is it a good idea to run multiple trytond services like this? We might even run 10, 20 or more.
Or should I learn Docker/Kubernetes/…?
We use Tryton 5.0

I do not see any issue with such settings. Indeed the demo servers was configured like this until 5.0. We switched to a docker setup for two reasons:

  • Simpler to manage (a single docker-compose configuration file)
  • Easier to manage old version which may require old Python modules or database

But I would say that in order to limit each Tryton server to connect to only compatible database, we used a different database user per server.
Or you can fill in ir.configuration the hostname from which the database can be connected (but it is less error prone).

Hi,

Other simple way of running tryton in production is this:

  • Virtualmin with LEMP stack installed on centos, ubuntu or debian server (nginx to use it like web and proxy server).
  • uWSGI to manage Tryton.
  • Postgresql.
  • Virtualenv (venv for python3).

With virtualmin you can to manage postgresql easily, create several virtual server with domains and have a database user to each tryton installation.We have 25 customers with this infraestructure currently.

one super easy way to use Docker/Kubernetes is RancherOS, we use it to tryton saas backup servers. test it :smiley:
