Hi Jason,

To be frank, I'm not thinking you referring a good repo. 

Your scenario could be split to two part:
a)  how to wrap odoo with nginx and let's encrypt cert (auto update)
     this is a common question, google will give you lots of good references (googling without the term odoo)
     for the only odoo related part is documented at here: https://www.odoo.com/documentation/14.0/setup/deploy.html#https

b) how to run odoo with docker container.
    you can refer here: https://hub.docker.com/_/odoo/ , and refer the docker-compose.yml part.


And for your question:
1) you could run db (container or not) at anywhere on any machine
    one postgres db instanace with two db in it (one for you and your friends) is ok;
    or two postgres db instanaces, one for you and one for your friend, is also ok.
 
2) I believe you shoud have two docker-compose.yml (if you run it on one machine, please do mapping to using different network ports!!!), one for you, and one for your friend.
    While in each docker-compose.yml, (if you plans to runs db on another machine), just get rid of the db service part (from the odoo docker page's example), while in odoo sevice section, using different odoo.conf to connect to different db - one for you and another for your friend.

Hi,

You can refer the blog below which explain the Odoo deployment using docker

Hi Jason, 

i would suggest that you use the docker-compose.yml provided by odoo. You can start the database container on a separate host and expose the databse to be reachable by the other machine running the odoo 'web' container. (or run both containers on your 'hidden' machine)… (https://hub.docker.com/_/odoo/)

For providing access to the 'web' container from the internet using lets encrypt i would suggest you use nginx-proxy-manager as a third container. It is a easy to setup and configure docker container with nginx and letsencrypt support – it has an administrative web interface for the proxy configuration. (https://github.com/jc21/nginx-proxy-manager)

You can then access https://erp.tempatkerja.com (nginx-proxy-manager) and forward the request to your http odoo web container.

Let me know if this helps or if you need more info... 

Best Regards,

Michael
