How to run more than one replicas?

Install/Maintain/Configure
1

I’m trying to run gitea in kubernetes and it works for single instance, but if I try to set replicaCount to 2, pods won’t start.

Error: INSTALLATION FAILED: template: gitea/templates/gitea/deployment.yaml:29:28: executing “gitea/templates/gitea/deployment.yaml” at <include (print $.Template.BasePath “/gitea/config.yaml”) .>: error calling include: template: gitea/templates/gitea/config.yaml:28:40: executing “gitea/templates/gitea/config.yaml” at <“cron.GIT_GC_REPOS”>: wrong type for value; expected map[string]interface {}; got string

Where does it come from? Do I need to change some other settings as well?
