Nice to see some interest on this project.
Yes I have a working odoo cloudron app instance for a year now. It's working well so far, and connected to the cloudron ldap server.
I will update the github repo with my latest changes, and will include a quick tested unmaintained github repo for odoo 12. For people who want to remix it, you have to modify the odooNNCE_install.sh, I'm using this MIT licenced script :
I had to change this script to make it fit with the cloudron packaging system, so feel free to fork the repo, I'll put my mods in MIT licence too.
PS: @jdaviescoates yes, we are running a similar setup than smart.coop. Smart is a generalist coop ; Babel.coop is a holacracy-powered self-organized coop. And the coop is focused on helping orgs to help themselves implementing self-managed org with the right digital "opensource-flavor" tools.
