How to configure hostname

Prerequisites

Deploy and relate nginx-ingress-integrator charm.

juju deploy nginx-ingress-integrator
juju relate wordpress-k8s nginx-ingress-integrator

Configure hostname

To configure a different hostname for WordPress, you can configure the ingress hostname through the wordpress-k8s configuration.

juju config wordpress-k8s blog_hostname=<desired-hostname>

The output of juju status should look similar to the following:

Model  Controller          Cloud/Region        Version  SLA          Timestamp
wordpress-k8s-tutorial    microk8s-localhost  microk8s/localhost  2.9.38   unsupported

wordpress-k8s                                  active      1  wordpress-k8s 16  <wordpress-k8s-ip>  no

Unit                         Workload  Agent  Address       Ports     Message
mysql-k8s/0*                active    idle   <mysql-k8s-ip>
nginx-ingress-integrator/0*  active    idle  <nginx-ingress-integrator-ip>            Service IP(s
): <nginx-ingress-integrator-service-ip>
wordpress-k8s/0*             active    idle   <wordpress-k8s-ip>

Note the Service IP(s): next to nginx-ingress-integrator charm’s Status output.

Test the ingress by sending a GET request to the service with Host headers.

curl -H "Host: <desired-hostname>" http://<nginx-ingress-integrator-service-ip>
