Howto configure the log rotation of the sidekiq logs?

I have a gitlab running in a docker instance.
The docker image I’m using is this one: “gitlab/gitlab-ee:latest”

I notice that every day I get a sidekiq logfile of about 66MB.
The log rotation is the default, so it’s set to 30 days.

I want to decrease this to 10 days to save some space.

I tried to edit my gitlab.rb, and set
sidekiq[‘logrotate_rotate’] = 10
and then run
gitlab-ctl reconfigure

but to no avail. the generated config file in
still contains:
And I still have 30 files there.

Are there other steps to accomplish this?
