Ingress traffic rejected by NetworkPolicy in Loki chart 6.5.0 (3.0.0)

[vholer]

Describe the bug

If network policy is enabled in Helm chart via networkPolicy.enabled=true and networkPolicy.ingress is configured, the traffic is still being rejected. This is due to a wrong port name reference http in NetworkPolicy:

loki/production/helm/loki/templates/networkpolicy.yaml

Line 69 in 19fef93

- port: http

while related Service port names are http-metrics:

loki/production/helm/loki/templates/gateway/service-gateway.yaml

Line 31 in 19fef93

- name: http-metrics

loki/production/helm/loki/templates/read/service-read.yaml

Line 27 in 19fef93

- name: http-metrics

loki/production/helm/loki/templates/write/service-write.yaml

Line 27 in 19fef93

- name: http-metrics

Recent change in gateway's Service broke this: 79b876b#diff-431f854797520c4320975bebaa267bcac088a12671e360093d87bf7193abd438R31

Expected behavior
Network policies should enable ingress traffic to gateway or reader/writer.

Environment:

• Infrastructure: Kubernetes
• Deployment tool: helm
