Ingress Setup

Ensure that the Kruise controller manager for the ingress-nginx module has started and is in the Running status.

d8 k -n d8-ingress-nginx get po -l app=kruise

Create an IngressNginxController resource that describes the parameters for the NGINX Ingress controller:

d8 k apply -f - <<EOF
# Section describing the NGINX Ingress controller parameters.
# https://deckhouse.io/products/virtualization-platform/reference/cr/ingressnginxcontroller.html
apiVersion: deckhouse.io/v1
kind: IngressNginxController
metadata:
  name: nginx
spec:
  ingressClass: nginx
  # Method of traffic entry from the outside world.
  inlet: HostPort
  hostPort:
    httpPort: 80
    httpsPort: 443
  # Describes which nodes will host the Ingress controller.
  # You might want to change this.
  nodeSelector:
    node-role.kubernetes.io/control-plane: ""
  tolerations:
  - effect: NoSchedule
    key: node-role.kubernetes.io/control-plane
    operator: Exists
EOF

The Ingress controller startup may take some time. Make sure the Ingress controller pods have transitioned to the Running status by running the following command:

d8 k -n d8-ingress-nginx get po -l app=controller

NAME                                       READY   STATUS    RESTARTS   AGE
controller-nginx-r6hxc                     3/3     Running   0          5m

DNS Configuration

To access the platform’s web interfaces, DNS records need to be configured for the cluster’s domain.

Using a Wildcard Domain

Ensure that the subdomains resolve to the IP address of the node where the Ingress controller is running. In this case, it is master-0. Also, verify that the name template matches the format %s.<domain>:

d8 k get mc global -ojson | jq -r '.spec.settings.modules.publicDomainTemplate'

%s.my-dvp-cluster.example.com

%s.54.43.32.21.sslip.io

Using Separate Domains Instead of a Wildcard Domain

If the template uses a non-wildcard domain, you need to manually add additional A or CNAME records pointing to the public IP address of the node where the nginx-controller is running. These records are required for all Deckhouse services.

For example, for the domain my-dvp-cluster.example.com and a template with subdomains %s.my-dvp-cluster.example.com, the records would look like this:

api.my-dvp-cluster.example.com
console.my-dvp-cluster.example.com
dashboard.my-dvp-cluster.example.com
deckhouse-tools.my-dvp-cluster.example.com
dex.my-dvp-cluster.example.com
documentation.my-dvp-cluster.example.com
grafana.my-dvp-cluster.example.com
hubble.my-dvp-cluster.example.com
kubeconfig.my-dvp-cluster.example.com
openvpn-admin.my-dvp-cluster.example.com
prometheus.my-dvp-cluster.example.com
status.my-dvp-cluster.example.com
upmeter.my-dvp-cluster.example.com

For the domain my-dvp-cluster.example.com and a template with individual domains %s-my-dvp-cluster.example.com, the records would look like this:

api-my-dvp-cluster.example.com
console-my-dvp-cluster.example.com
dashboard-my-dvp-cluster.example.com
deckhouse-tools-my-dvp-cluster.example.com
dex-my-dvp-cluster.example.com
documentation-my-dvp-cluster.example.com
grafana-my-dvp-cluster.example.com
hubble-my-dvp-cluster.example.com
kubeconfig-my-dvp-cluster.example.com
openvpn-admin-my-dvp-cluster.example.com
prometheus-my-dvp-cluster.example.com
status-my-dvp-cluster.example.com
upmeter-my-dvp-cluster.example.com

For testing, you can add the necessary records to the /etc/hosts file on your local machine (for Windows, the file is located at %SystemRoot%\system32\drivers\etc\hosts).

For Linux, you can use the following commands to add the records to the /etc/hosts file:

export PUBLIC_IP="<PUBLIC_IP>"
export CLUSTER_DOMAIN="my-dvp-cluster.example.com"
sudo -E bash -c "cat <<EOF >> /etc/hosts
$PUBLIC_IP api.$CLUSTER_DOMAIN
$PUBLIC_IP console.$CLUSTER_DOMAIN
$PUBLIC_IP dashboard.$CLUSTER_DOMAIN
$PUBLIC_IP deckhouse-tools.$CLUSTER_DOMAIN
$PUBLIC_IP dex.$CLUSTER_DOMAIN
$PUBLIC_IP documentation.$CLUSTER_DOMAIN
$PUBLIC_IP grafana.$CLUSTER_DOMAIN
$PUBLIC_IP hubble.$CLUSTER_DOMAIN
$PUBLIC_IP kubeconfig.$CLUSTER_DOMAIN
$PUBLIC_IP openvpn-admin.$CLUSTER_DOMAIN
$PUBLIC_IP prometheus.$CLUSTER_DOMAIN
$PUBLIC_IP status.$CLUSTER_DOMAIN
$PUBLIC_IP upmeter.$CLUSTER_DOMAIN
EOF

Creating a User

To access the cluster’s web interfaces, you can create a static user:

1. Generate a password:

   echo -n '<USER-PASSWORD>' | htpasswd -BinC 10 "" | cut -d: -f2 | tr -d '\n' | base64 -w0; echo
   

   <USER-PASSWORD> — the password to be set for the user.

2. Create the user:

   d8 k create -f - <<EOF
   ---
   apiVersion: deckhouse.io/v1
   kind: ClusterAuthorizationRule
   metadata:
     name: admin
   spec:
     subjects:
     - kind: User
       name: admin@deckhouse.io
     accessLevel: SuperAdmin
     portForwarding: true
   ---
   apiVersion: deckhouse.io/v1
   kind: User
   metadata:
     name: admin
   spec:
     email: admin@my-dvp-cluster.example.com
     password: '<BASE64 PASSWORD>'
   
   EOF
   

Now you can log in to the cluster web interfaces using your email and password. For further configuration, it is recommended to review the section Access Control / Role Model.

Enable console module

The console module allows you to manage virtualization components through the Deckhouse web interface.

To enable the module, run the following command:

d8 s module enable console
