BullMQ in K8

[Haris-SP4RKy]

I have bullMQ configured in my project for scheduling of jobs using repeatable.
The issue is that I can see that through bull board that job always runs in attempt 2

I have 3 instances of the project running behind the load balancer
So it means 3 workers running for a queue
How the job is distributed among the workers?
How to make sure job is executed by a single worker, not by all 3 of them

What if my job can run up to 1 min? Will it affect anything? How to handle it?
