Hello, i want to overwrite this configuration by using environment variables.So which one is correct? Thanks!
Copy code
export PREFECT__SERVICES__SERVICES__TOWEL__MAX__SCHEDULED__RUNS__PER__FLOW=1

export PREFECT__MAX__SCHEDULED__RUNS__PER__FLOW=1

I'd say: PREFECT__SERVICES__TOWEL__MAX_SCHEDULED_RUNS_PER_FLOW

i set ~/.prefect/config.toml like this
Copy code
[server]
    [server.ui]
    port = "8081"
    host_port = "8081"

[services]

    host = "0.0.0.0"

    [services.towel]
    max_scheduled_runs_per_flow = 1
ui port change is ok, but max_scheduled_runs_per_flow doesn’t work, still has 10 upcoming runs

Did you re-deploy server? You need to de-redeploy for these changes to take effect

Did you deploy with helm or
prefect server start
?

Prefect server start should definitely use that and it seems like the right place. Do you potentially have an env var set also?
Or another config.toml?

Same for me, changes in the [services] section don't seem to be picked up by server (using 1.3).
Lookin at the code it seems that these values are not passed to server when running
prefect server start
, so the values hard coded in https://github.com/PrefectHQ/server/blob/5d2c538dac3c246fcafc1ec2556f46bdf987f0fc/src/prefect_server/config.toml#L85 are used.
I tried to launch server and then change the value in the towel container (
docker exec -it
intothe container then modify the config.toml file using python), but that does not work either, since the config is loaded only once during start-up.
