Why not to use string instead of int? #124

I tried to use helm chart to deploy Packet Rusher to Kubernetes Cluster. The type of gnodeb.slicesupportlist.sst in config.yml is string while ue.snssai.sst is integer. This make entrypoint.sh hard to replace ENV variable to integer, can you modify the type to string?

Hi @brianchennn,

I think the rationale to use int instead of string was to enforce that SST was mandatory while SD was not. Though it's stupid (especially since slicesupportlist and snssai should have the same format), and we need a proper configuration validator instead. We indeed need to fix that! By the way, you may also want to take a look at Gradiant's PacketRusher Helm Chart which does not use our entrypoint and instead just generate a config.yml out of a template: https://github.com/Gradiant/5g-charts/tree/main/charts/packetrusher

Cheers, Valentin
