Disabling ingress-nginx port 80

Products

• DX Operational Observability

Issue/Introduction

kubectl get ingresses shows TCP 80 listener for all services, we need to disable port 80 to meet our security requirements.

Environment

DX O2 OnPremise

Resolution

When ssl is enabled by default the http will be redirected to https routes so even if someone accesses ingress with http the traffic will be redirected automatically to 443.  You can safely ignore 80 port, see ingress-nginx documentation
