How to configure the hostname
This guide provides instructions for configuring the external hostname of the Discourse charm.
Prerequisites
Deploy and relate nginx-ingress-integrator charm.
juju deploy nginx-ingress-integrator
juju trust nginx-ingress-integrator --scope cluster # if RBAC is enabled
juju relate discourse-k8s nginx-ingress-integrator
Configure hostname
This charm exposes the external_hostname configuration option to specify the external hostname of the application.
To configure a different hostname for Discourse, you can configure the ingress hostname through the discourse-k8s configuration.
juju config discourse-k8s external_hostname=<desired-hostname>
The output of juju status should look similar to the following:
Model Controller Cloud/Region Version SLA Timestamp
tutorial mk8s microk8s/localhost 2.9.44 unsupported 18:19:34-04:00
App Version Status Scale Charm Channel Rev Address Exposed Message
discourse-k8s 2.8.14 active 1 discourse-k8s 41 <discourse-ip> no

postgresql-k8s/0* active idle <postgres-ip> Primary
redis-k8s/0* active idle <redis-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://<ingress-svc-ip>
