Increase Configuration Cache on Docker Deployment

[techmattr]

I'm using a 6.2 deployment with the official compose file: docker-compose_v3_ubuntu_pgsql_latest.yaml
How would I go about increasing the configuration cache size? I've added 45 servers so far and I'm at about 85%.

I found ZBX_CACHESIZE=8M in env_vars/.env_srv and changed that to 256M. However, I'm not sure if that is the correct value to edit and I'm not sure how to recreate the container to pick up the new value?

The correct commands to reload the container and pickup the new variables if your compose file is named docker-compose.yml. If it is not then specify the file with -f

docker compose stop zabbix-server
docker compose create zabbix-server
docker compose start zabbix-server

I fixed this by changing these two values in env_vars/.env_srv

ZBX_CACHESIZE=256M
ZBX_VALUECACHESIZE=256M

They were both commented out so I'm not sure what the default value is but I went from 80-90% used on both to about 10% used.
To reload the container with the new values I ran the following commands

docker compose stop zabbix-server
docker compose up

I think this may have screwed some things up though. My problems are not appearing properly in the dashboard. "docker compose up" rebuilt all of my containers. It didn't wipe out the database because all of my hosts and configurations were still in Zabbix but things haven't been working right since.
I think the correct commands may have been

docker compose -f docker-compose_v3_ubuntu_pgsql_latest.yaml stop zabbix-server
docker compose -f docker-compose_v3_ubuntu_pgsql_latest.yaml zabbix-server up -d

Also, if you have MSSQL drivers installed in your zabbix-server container or anything else installed; that will be lost and need re-installed/configured.
