< p > This example shows how to add authentication in a Ingress rule using a secret that contains a file generated with < code class = "codehilite" > htpasswd< / code > .
It's important the file generated is named < code class = "codehilite" > auth< / code > (actually - that the secret has a key < code class = "codehilite" > data.auth< / code > ), otherwise the ingress-controller returns a 503.< / p >
