Question: Principe of distributing of tasks among Semaphore Runners

[klavik]

Question

Hello, Guys! First of all thank you for such helpful opensource product. I really like it and want to use in my environment as a helpful instrument to run and control ansible playbooks.
So, now I'm trying to build setup with 1 "Semaphore Sever" and 2 "Semaphore Runners" with git repo for inventory and playbooks.
I'm stuck in understanding how balancing works for case with 2 or more SR? Documentation says "You can start multiple runners, and tasks will be randomly distributed among them." But my tests show that when I start 2 or more playbooks simultaneously using webui of SS, all of them go to only 1 SR from 2 connected. I set "infinite" for parallel setting in Runner.
Could you be so kind and explain the principe of distributing of tasks among SR?

I use 2.12.5

Hi @klavik

Thank you for your question. Yes, you are right. Current logic a bit different and require improvement.

Currently if you have runner with "infinite" tasks all tasks can forwarded to it.

The logic will be improved in following releases.

Currently you can limit number of parallel tasks for runner to distribute tasks among runners.

Thanks a lot @fiftin. Now its clear. One more question about parallel setting of Runners. I tested that can change this setting using webUI, and can I adjust it in config.runner.json? If yes, could you give example of parameter?
