Readme: obsolete docker flag (--link)

[rossthom]

I want to run Odoo 16 from docker following the instructions written on the README file.
When executing the command line on § 'Start an Odoo instance': $ docker run -p 8069:8069 --name odoo --link db:db -t odoo,
I get the following docker error:

Emulate Docker CLI using podman. Create /etc/containers/nodocker to quiet msg.
Error: unknown flag: --link
See 'podman run --help'

the --link flag is deprecated : https://docs.docker.com/network/links/
The command line needs to be updated on the documentation.

hi,
it worked normal for me, did you run this one before ? : $ docker run -d -e POSTGRES_USER=odoo -e POSTGRES_PASSWORD=odoo -e POSTGRES_DB=postgres --name db postgres:15

mh, I'll need to find some time to retry. I don't remember whether I used this exact command line.

@rossthom to update the Overview listed on Docker Hub you can create a PR editing the file https://github.com/docker-library/docs/blob/master/odoo/content.md

I am updating the content.md for some other issues and this is next in my queue. Brainstorming on how to word this here.

Currently

Start a PostgreSQL server

$ docker run -d -e POSTGRES_USER=odoo -e POSTGRES_PASSWORD=odoo -e POSTGRES_DB=postgres --name db postgres:15

Start an Odoo instance

$ docker run -p 8069:8069 --name odoo --link db:db -t odoo

Could Become

Start a network where the container names in the network are populated in `/etc/hosts`

$ docker network create my-odoo-network

Start a PostgreSQL server

$ docker run -d -e POSTGRES_USER=odoo -e POSTGRES_PASSWORD=odoo -e POSTGRES_DB=postgres --name db --net=my-odoo-network postgres:15

Start an Odoo instance

$ docker run -p 8069:8069 --name odoo --net=my-odoo-network -t odoo
