Notes for using Odoo18 on an Unraid server via the CA installation

• Installing the Odoo container in Unraid... I didn't need to adjust anything from the defaults in the template
• Installing PostgreSQL was also straight-forward and you'll only need to note down the settings you select here to transpose into the 'odoo.conf' file (detailed below)
• The support thread for this container is located in the Unraid Forums here, please post any questions or contributions

IMPORTANT NOTE

I hit a couple of odd error's, most likely my own fault... I needed to use the Extra Parameters in the Unraid template 'ADVANCED VIEW', with the value set as --user=100:101 due to having some issues with the container being able to write to the 3 mapped volumes

The process I followed was to check the uid and gid in the Odoo18 container with docker exec -it Odoo18 sh -c 'echo "uid=$(id -u) gid=$(id -g)"' which returned uid=100 gid=101
I then manually made the folder I had seen in the error logs with mkdir -p /mnt/user/appdata/odoo18/data/sessions
Then to CHOWN the folders with chown -R 100:101 /mnt/user/appdata/odoo18
And, finally CHMOD the folders with chmod -R 775 /mnt/user/appdata/odoo18
I was good from the next restart of the Odoo18 container

After installing Odoo, return to Unraid to view the container template in 'ADVANCED VIEW'
We will need to make a change to the Post Arguments section to avoid having a security exposure open via a default Admin account
The Post Arguments need to be removed after the initial first successful boot

• I have used the -i base command as Odoo18 wouldn't initialise it's DB during it's first startup
• The -i base command must be removed to make for a safe environment

TO INSTALL WITHOUT DEMO DATA

• To initialise the Odoo18 database without DEMO data being installed by default change your Post Arguments to be
  -i base --without-demo=all --stop-after-init
• This will initialise Odoo18, then NOT install the demo data, and finally will stop Odoo18 from running.
• Please restart your container after removing -i base --without-demo=all --stop-after-init from your Post Arguments

INSTALLATION STEPS

1. The odoo.conf file needs to be copied in to the Config Location path on Unraid server
   The Config Location path is selected by you in the Odoo18 settings when installing in Unraid CA
   Your typical Config Location path may be at /mnt/user/appdata/odoo18/config

2. My odoo.conf file if you'd like to use it
   For my path (above), within the Unraid Shell / CLI:

•     cd /mnt/user/appdata/odoo18/config
•     wget https://raw.githubusercontent.com/Eurotimmy/unraid-templates/main/Odoo18/odoo.conf
•     nano odoo.conf

1. The odoo.conf file needs to be edited and then your Odoo Docker container needs to be started / restarted:

  admin_passwd = (This password will become hashed on first start-up, for security reasons)
  db_host = (Use the IP address assigned to the PostgreSQL container, in the 'Docker' tab)
  db_port = (Enter what your PostgreSQL 'Container Port' is set to, from your PostgreSQL install)
  db_user = (Enter what your PostgreSQL 'POSTGRES_USER' is set to, from your PostgreSQL install)
  db_password = (Enter what your PostgreSQL 'POSTGRES_PASSWORD' is set to, from your PostgreSQL install)
  db_name = (Enter what your PostgreSQL 'POSTGRES_DB' is set to, from your PostgreSQL install)

1. Once your container starts, open the Odoo Web UI from your Odoo icon

•    Username: admin
•    Password: admin

NPM (Nginx Proxy Manager) - Reverse Proxy settings

I am using NPM to reverse proxy my Odoo instance via my own domain name
You will need to edit your odoo.conf file (in your Config Location) to include proxy_mode = True
In NPM on my odoo.example.com domain I use the following in my location settings (within the 'Advanced' tab)

    proxy_pass $forward_scheme://$server:$port;
    proxy_set_header X-Forwarded-Host $http_host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_redirect off;
