How to pass ' -search.maxUniqueTimeseriesi' flag to in victoriametrics?

Question

As the database got bigger we faced this problem:

the number or matching unique timeseries exceeds 300000; either narrow down the search or increase -search.maxUniqueTimeseries

The Docs show a solution:

On large databases you may experience problems with limit on unique timeseries (default value is 300000). In this case you need to adjust -search.maxUniqueTimeseries parameter:

count unique timeseries in database

wget -O- -q 'http://your_victoriametrics_instance:8428/api/v1/series/count' | jq '.data[0]'

relaunch victoriametrics with search.maxUniqueTimeseries more than value from previous command

The docker-compose file looks now something like this:

victoria-metrics:
image:
dns_search:
environment:
command:
- '--search.maxUniqueTimeseries=1000000'

this still doesn't solve the problem.

How can I pass the flag in docker compose correctly?

UPDATE

The image I was using didn't take flags from docker-compose.yml to consideration. This was the problem.

this still doesn't solve the problem.

Do you mean the flag isn't set? Can you check the following metric flag{name="search.maxUniqueTimeseries" on VicotriaMetrics /metrics page? Or via the following command:

curl http://<vm-address>:8428/metrics | grep maxUniqueTimeseries
