juju deploy discourse-k8s
You will need Juju 2.9 to be able to run this command. Learn how to upgrade to Juju 2.9.
Deploy Kubernetes operators easily with Juju, the Universal Operator Lifecycle Manager. Need a Kubernetes cluster? Install MicroK8s to create a full CNCF-certified Kubernetes system in under 60 seconds.
In this tutorial, we’ll walk you through the process of deploying the Discourse charm, relating it to the nginx-ingress-integrator charm, the postgresql-k8s charm and the redis-k8s charm, and inspecting the kubernetes resources created.
You will need:
- A laptop or desktop running Ubuntu (or you can use a VM).
Juju and Microk8s installed. We’ll also want to make sure the ingress add-on is enabled, which we can do by running
microk8s enable ingress.
Deploy this charm
Discourse requires connections to PostgreSQL and Redis, so those will be deployed too and related to the Discourse charm. For more information, see the Charm Architecture.
All the above charms will the deployed in a new model named
# Add the model juju add-model discourse # Deploy the charms juju deploy redis-k8s juju deploy postgresql-k8s juju deploy discourse-k8s # Relate redis-k8s and postgresql-k8s to discourse-k8s juju relate redis-k8s discourse-k8s # For postgresql-k8s the "db" interface needs to be specified as the charm provides more than one juju relate discourse-k8s postgresql-k8s:db
juju status --relations the current state of the deployment can be queried, with all the charms eventually reaching

kubectl get pods -n discourse to see the pods that are being created by the charms:

In order to expose the charm, the Nginx Ingress Integrator is to be deployed alongside Discourse to provide ingress capabilities
juju deploy nginx-ingress-integrator # If your cluster has RBAC enabled you'll be prompted to run the following: juju trust nginx-ingress-integrator --scope=cluster juju relate discourse-k8s nginx-ingress-integrator
Discourse will be deployed with
discourse-k8s as default hostname. In order to reach it, modify your
/etc/hosts file so that it points to
echo 127.0.0.1 discourse-k8s >> /etc/hosts
After that, visit
http://discourse-k8s to reach Discourse.
This charm allows you to add a admin user by executing the corresponding action. Instead of interacting with the Discourse UI just run
juju run-action discourse-k8s/0 add-admin-user firstname.lastname@example.org password=somepwd --wait and it will be registered and validated.
