Configure networking

This section explains what must be configured from a networking perspective to get HCL Digital Experience 9.5 running in your Kubernetes or OpenShift cluster, and to provide accessibility to your deployment from outside the Cluster.

Full Kubernetes or OpenShift deployment

If you deploy both Core and all other applications inside OpenShift or Kubernetes, this section shows you what needs to be configured.

Core host

In a full deployment, the host for both the Core and the other applications are the same.

It is recommended to configure the host before you run the deployment. This is only possible if you know the fully qualified domain name (FQDN) or the IP address that the HAProxy assigns in your deployment beforehand.

If that is the case, define the host using the following syntax:

# Networking specific configuration networking: # Networking configuration specific to Core core: # Host of Core host: ""

If you do not know the hostname beforehand, you can leave it blank and run an additional step later in the installation, which would retrieve the assigned hostname from HAProxy and configure all applications accordingly.

Configure Cross Origin Resource Sharing (CORS)

The HCL Digital Experience 9.5 Helm Chart allows you to configure CORS configuration for all the addon to Core applications such as Digital Asset Management or Ring API. This allows you to access the APIs provided by those applications in other applications with ease.

You can define a list of allowed hosts for a specific application using the following syntax in your custom-values.yaml:

   # Networking specific configuration
     # Networking configurations specific to all addon applications
         # CORS Origin configuration for Content Composer, comma separated list
         corsOrigin: ","               

Refer to the HCL DX 9.5 values.yaml detail for all possible applications that can be configured.

Hybrid host

Configuring Hybrid Host

In a Hybrid deployment, the host for the on-premise DX Core will be added in the core configuration section and the other applications host will be placed under the add-on section. See the following example:

    # Networking configuration specific to Core
      # Host of Core, must be specified as a FQDN
      # If you are running hybrid, you need to specify the FQDN of the on-premise Core 
      # Example:
      host: ""
      port: "10042"
      contextRoot: "wps"
      personalizedHome: "myportal"
      home: "portal"
      # Host of the addon applications
      # If you are not running hybrid, you can leave this value empty and the Core host 
     will be used
      # If you are running hybrid, you need to specify the FQDN of the Kubernetes 
      # Example:
      host: ""
      # Port of the addon applications
      # If you are running hybrid, you can specify a port
      # If left empty, no specific port will be added to the host
      port: "443"
      # Setting if SSL is enabled for addon applications
      # If you are running hybrid, make sure to set this accordingly to the Kubernetes 
     deployment configuration
      # Will default to true if not set    
      ssl: "true"

Please refer to the original values.yaml for all available applications that can be configured. See the Planning your container deployment using Helm topic for details.

Configure HAProxy certificate

For HAProxy to allow forward requests to your applications, you must provide it with a TLS Certificate. This certificate is used for incoming/outgoing traffic from the outside of the Kubernetes or OpenShift cluster to your applications. HAProxy performs TLS offloading.

Generate self-signed certificate

It is recommended that you use a properly signed certificate for HAProxy. However, it is also possible to create and use a self-signed certificate, for example, for staging or testing environment.

Creation of that certificate can be achieved using the following commands for OpenSSL:

   # Creation of a private key
   openssl genrsa -out my-key.pem 2048

   # Creation of a certificate signed by the private key created before
   openssl req -x509 -key my-key.pem -out my-cert.pem -days 365 -subj '/CN=my-cert'

This provides you with a key and cert file that can be used in the next step, creation of the certificate to your deployment.

Use certificate

Create secret

To have your deployment and HAProxy to use the certificate, you must store it in the Kubernetes or OpenShift cluster as a secret.

The secret can be created using the following commands:


The secret name can be chosen by you and must be referenced in the next configuration step (the following example uses dx-tls-cert). The namespace is the Kubernetes namespace where you want to deploy HCL Digital Experience 9.5 to (the example uses digital-experience).

   # Create secret with the name "dx-tls-cert"
   # Secret will be created in the namespace "digital-experience"
   # You can either reference the cert and key file created before, or a proper signed certificate e.g. from your CA
   kubectl create secret tls dx-tls-cert --cert=my-cert.pem --key=my-key.pem -n digital-experience 

Configure secret in deployment

You need to make sure that the reference to the secret is set up correctly in your custom-values.yaml. Otherwise, HAProxy cannot answer HTTPS requests due to a missing certificate.

You can set the name of the certificate used with the following syntax, the default value is dx-tls-cert:

   # Networking specific configuration
   # TLS Certificate secret used for haproxy
    tlsCertSecret: "dx-tls-cert"            


Verify you have entered the correct name.
