Set dbindex to separate data in a single Redis instance by environment variable

[f466162]

Hi,

I want to share a single Redis instance and use it with several independent applications. Thus, I need a way to specify the dbindex. As I'm using a Docker deployment, I'd like to add the dbindex using an environment variable. For my Nextcloud 19 (i.e. "production") installation, I tested the following way. As I cannot test for different Nextcloud versions, I made this change only in the Nextcloud 19 folder. Perhaps the if-statement can be reused for different Nextcloud versions and can be copy/pasted.

Regards
Fabian

Hello,
I have the same requirement.
But setting the dbindex in the nextcloud config is not enough by itself. You also need to update the dbindex in the entrypoint.sh for the /usr/local/etc/php/conf.d/redis-session.ini file.

Thanks a lot!

Regards
Stefan

Any updates? I think this would be pretty useful :/

In what case is this useful? The recommend deployment is to use a dedicated Redis container for each independent application.

It seems a better approach to this is to have many Redis instances.
Correct me if I'm wrong, but Redis in mono-threaded so having many databases in same instance will create a bottleneck in performances.
You can easily create many instances on different ports :

and then set correct config on each nextcloud instance.
