 **Important:** do not create any user until you changed id maping in lxc conf (see [Mounting volumes](#mounting-volumes)). And also think about creating off user before any other user to avoid having to change users uids, off must have uid 1000.

 ## Mounting volumes
 
 In production we have off, obf, opf and opff in off2, so we cross mount their products and images volumes.

+### nginx for OBF (inside container)
 
 Installed nginx `sudo apt install nginx`.
 
 Removed default site `sudo unlink /etc/nginx/sites-enabled/default`
 
-On off2, Copied production nginx configuration of off1:
-```
-# base configs
-sudo scp 10.0.0.1:/etc/nginx/sites-enabled/obf /zfs-hdd/pve/subvol-111-disk-0/srv/obf/conf/nginx/sites-available/

-sudo chown 1000:1000 -R  /zfs-hdd/pve/subvol-112-disk-0/srv/opf/conf
-```
-
-I added /srv/obf/conf/nginx/conf.d/log_format_realip.conf (on obf), same for opf, with same content as the one on opff (it's now in git).
+We are going to mimick the setup that we have in the off container.
 
 Then made symlinks:
 * For obf:
   ```bash
-  sudo ln -s /srv/obf/conf/nginx/sites-available /etc/nginx/sites-enabled/obf
-  sudo ln -s /srv/obf/conf/nginx/snippets/expires-no-json-xml.conf /etc/nginx/snippets
-  sudo ln -s /srv/obf/conf/nginx/snippets/off.cors-headers.include /etc/nginx/snippets
-  sudo ln -s /srv/obf/conf/nginx/conf.d/log_format_realip.conf /etc/nginx/conf.d
+  sudo ln -s /srv/obf/conf/nginx/sites-available/obf /etc/nginx/sites-enabled/obf
+  sudo ln -s /srv/obf/conf/nginx/snippets/expires-no-json-xml.conf /etc/nginx/snippets/
+  sudo ln -s /srv/obf/conf/nginx/snippets/expiry-headers.include /etc/nginx/snippets/
+  sudo ln -s /srv/obf/conf/nginx/snippets/off.cors-headers.include /etc/nginx/snippets/
+  sudo rm -rf /etc/nginx/conf.d
+  sudo ln -s /srv/obf/conf/nginx/conf.d /etc/nginx/
   sudo rm /etc/nginx/mime.types
   sudo ln -s /srv/obf/conf/nginx/mime.types /etc/nginx/
   ```
-* For opf:
-  ```bash
-  sudo ln -s /srv/opf/conf/nginx/sites-available /etc/nginx/sites-enabled/opf
-  sudo ln -s /srv/opf/conf/nginx/snippets/expires-no-json-xml.conf /etc/nginx/snippets
-  sudo ln -s /srv/opf/conf/nginx/snippets/off.cors-headers.include /etc/nginx/snippets
-  sudo ln -s /srv/opf/conf/nginx/conf.d/log_format_realip.conf /etc/nginx/conf.d
-  sudo rm /etc/nginx/mime.types
-  sudo ln -s /srv/opf/conf/nginx/mime.types /etc/nginx/
-  ```
 
-On obf and opf Modified their configuration to remove ssl section, change log path and access log format, and to set real_ip_resursive options (it's all in git)
+I then copied the off config file to obf, as lots of things have changed:
+
+```bash
+sudo cp /srv/obf/conf/nginx/sites-available/off /srv/obf/conf/nginx/sites-available/obf
+```
+
+And edited the file to change openfoodfacts.org to openbeautyfacts.org, the name of the log files etc. The result is in git.
+
+I create an empty /srv/obf/conf/nginx/snippets/obf.domain-redirects.include + obf.locations-redirects.include , they might be used if we want to create subdomains shortcuts or redirects on OBF as we have on OFF.
 
-test it:
 ```bash
-sudo nginx -t
+sudo ln -s /srv/obf/conf/nginx/snippets/obf.domain-redirects.include /etc/nginx/snippets/
+sudo ln -s /srv/obf/conf/nginx/snippets/obf.locations-redirects.include /etc/nginx/snippets/
