Empty database after upgrade 2.1.0 -> 3.0.0 #766
Description
After upgrading GreedyBear to version 3.0.0 on one of my instances all historic data disappeared. After some investigation I noticed that the application uses the wrong docker volume.
> sudo docker inspect greedybear_postgres --format '{{json .Mounts}}' | python3 -m json.tool [ { "Type": "volume", "Name": "5ed93ca33747f82767cf26389827376700ca472dbeb05a5fff8ab9f759f87e07", "Source": "/var/lib/docker/volumes/5ed93ca33747f82767cf26389827376700ca472dbeb05a5fff8ab9f759f87e07/_data", "Destination": "/var/lib/postgresql", "Driver": "local", "Mode": "", "RW": true, "Propagation": "" }, { "Type": "volume", "Name": "greedybear_postgres_data", "Source": "/var/lib/docker/volumes/greedybear_postgres_data/_data", "Destination": "/var/lib/postgresql/data", "Driver": "local", "Mode": "z", "RW": true, "Propagation": "" } ] As can be seen, there are two volumes available for the postgres container. After the update, for some reason the application decided to use the first one, although the data lives in the second one.
