in lightning lab 1, q2, we debug connectivity and find that network policy is stopping all ingress traffic, in solution they have created a new network policy… what if we alter existing netpol to accept all ingress traffic? is that a valid solution?
Deleting or editing the netpol will also work . simplest is to not edit any existing and create a new netpol as network policies are additive union of all network policies applied on a pod .
as per the info in the link https://kubernetes.io/docs/concepts/services-networking/network-policies/
