Create-a-DB-dump.md

+Some times we need a db dump to attach it to a support ticket to help the OC team.
+
+The next steps are used to extract a dump of the `opencell` db:
+
+1. Access to the server:
+
+```
+$ ssh opencell-test.coopdevs.org
+```
+
+2. Change to the `opencell` user:
+
+```
+$ sudo su - opencell
+```
+
+3. Access to the db container:
+
+```
+$ docker exec -ti postgres bash
+```
+
+4. Create the dump:
+
+```
+# pg_dump -U opencell -W -f opencell.19.08.07.dump opencell
+```
+
+5. Exit and copy the dump out of the container:
+
+```
+# exit
+exit
+$ docker cp postgres:/opencell.19.08.07.dump .
+```
+
+6. Move the dump to your user home and change the permissions:
+
+```
+$ exit
+logout
+daniel@opencell-test:~$ sudo chown daniel:daniel /home/opencell/opencell.19.08.07.dump 
+daniel@opencell-test:~$ sudo mv /home/opencell/opencell.19.08.07.dump .
+```
+
+6. Copy the dump form the server to your machine:
+
+```
+$ logout
+Connection to opencell-test.coopdevs.org closed.
+
+$ scp opencell-test.coopdevs.org:opencell.19.08.07.dump .
+opencell.19.08.07.dump                                                                                                                                                                                      100% 1027KB   2.5MB/s   00:00
