I want to change MaxChannels value, it is inside the qm.ini file. Is there any option with helm variable or do i need to rebuild image?
If you are using the IBM sample Helm Chart available here, you can specify a qm.ini within a Kubernetes configMap and then reference this as part of the Helm deployment. Each of the samples already reference a qm.ini which you can use as an example. The qm.ini is created within a ConfigMap here, and referenced here.
