Ingress configurations in helm values files. The following setup assumes that you have a helm chart which provides the configuration to deploy a service and an ingress for it
Now, lets look at few of the sample helm values file configurations for ingress configurations with ingress-nginx.
Enable Cors#
ingress:

pathType: PrefixExternal Authentication#
External Authentication configuration based from doc
ingress:
enabled: true
annotations:

# response urls to be returned from auth service and passed to services
nginx.ingress.kubernetes.io/auth-response-headers: "X-Header1, X-Header2, X-Header3"
hosts:

hosts:
- host: ravikrs.com
paths:
- path: /test
pathType: PrefixPath Rewrite#
Rewrite path /service1/swagger url to /swagger/ path for kubernetes service exposing deployment. See docs
ingress:

nginx.ingress.kubernetes.io/rewrite-target: /swagger/$1
hosts:
- host: ravikrs.com
paths:
- path: /service1/swagger/(.*)
pathType: PrefixUse Regex in Path#
We may also use regular expression to handle ingress path configurations. See docs
ingress:
enabled: true
annotations:
kubernetes.io/ingress.class: nginx
nginx.ingress.kubernetes.io/use-regex: "true"
