Ingress controller failing in RKE1 with port conflict when using port 8443
This document (000021261) is provided subject to the disclaimer at the end of this document.
Environment
RKE1
Situation
When deploying the ingress controller on RKE1 with custom configuration as below
ingress:
extra_args:
http-port: '8080'
https-port: '8443'
http_port: 8080
https_port: 8443
Ingress controller deployment is failing with the following error
“2023/08/22 12:42:08 [emerg] 20#20: bind() to 0.0.0.0:8443 failed (98: Address in use)”
Resolution
Either keep the default port used by the ingress-nginx container by removing the extra_args.https-port, or use a different port like 7443 which will avoid the conflict
ingress:
http_port: 8080
https_port: 8443
However, you may use any port for the ingress.https_port as it denotes the hostPorts field for the ingress pods, the port used for external access
Cause
Port 8443 is configured with extra_args.https-port which conflicts with the internal port 8443 bound for the validating webhook also provided by the ingress-nginx pod
