Ingress

Be careful when thinking about an "Ingress Resource"!

This should not be confused with the actual "Ingress Controller", which is just a pod running nginx that performs traffic routing as if you were performing a bunch of re-writes.
Ingress with SSL & Basic Auth
Setting up Basic Auth is pretty straightforward as you only need to generate the htpasswd token and create the kubernetes secret before creating your ingress resource. If the htpasswd command isn't present on your machine you can install it with apt-get install apache2-utils.
Create credentials file & kubernetes secret
create-secret.sh
1
htpasswd -cb auth $(USERNAME) $(PASSWORD)
2
kubectl create secret generic "nginx-ingress-basic-auth" --from-file="auth"
3
The secret created will look like this:
4
apiVersion: v1
5
kind: Secret
6
metadata:
7
  name: nginx-ingress-basic-auth
8
type: Opaque
9
data:
10
  auth: dXNlcjp5LWJhc2g1LkQuRlJTdDlvU0tieDByN2pFaXJiaHEuSmNLaUZScUJWRw==
