I installed Sentry using the example docker-compose in this repository:
After some hours I
docker-compose down, moved the
sentry/postgres volumes data to other places in my VPS, updated the docker-compose volume paths, and
docker-compose up. At first a config mistake I did made postgres recreate an empty DB. But after another down/up I fixed it, and postgres used the same old DB, but from the new place I pointed the volume to.
After the last
docker-compose up everything was right, except the bar charts with events counts per hour/day. They all displayed 0, even if the events were there. New events seem to increase bar count accordingly, but not for the old ones.
I’m not sure if I understood this thread right, but maybe that kind of data is saved on Redis?
Is that right? If so, maybe the example docker-compose should be updated to store Redis data in a volume? If that makes sense for Redis, I don’t know it very well… If not, will that data always be lost on container recreation?
It also would be helpful if the docs made clear what had to be saved in a backup/restore procedure. My guess was to backup the volumes in the docker-compose, but it seems they aren’t enough in this case.
For curiosity´s sake, is there a way to regenerate the bar charts data based on the events in the database?
