Custom domains

A custom domain is a unique name that identifies your website. There are scenarios where you do not want to expose the default domain provided by IBM®. In such cases, you can customize the default tenant URL or domain and access the tenant using your own domain. Use custom domains if you want to make your application accessible on your own domain. Custom domains direct requests to your own URL.

You can request for a custom domain name for your tenant, for example, if your company domain is abc.com, you can have the domain name as https://subdomain.abc.com. Contact IBM Support for details on how to enable and configure the custom domain capability.

Steps to configure custom domains

  1. Determine the number of domains to be configured for your account and the list of custom domains. The domain names are owned by you.

  2. Decide the SSL certificate needed, which depends on whether you want to protect a single domain, multiple subdomains of a domain, or multiple domain names.

  3. Share the number of domains to be configured for your account and the list of custom domains with IBM.

  4. IBM will create a certificate signing request (CSR) and will provide you the details.

  5. Based on the CSR, get the SSL certificates from a Certificate Authority (CA) and determine the number and type of domains you want to be protected by the certificates.

  6. Send the SSL certificates to IBM to configure the certificates on the custom domain load balancer.

  7. IBM will send you the CNAME. Using the CNAME, configure your DNS to point to the custom domain load balancer.

  8. After the configuration is complete, you can start using the custom domain to access IBM webMethods Cloud Container.

Checks for existing assets after configuring custom domains

  • External end points will change after the custom domain is configured, so you need to inform your partners about the new domain.
  • Verify all assets that expose end point URLs, for example, REST APIs, SOAP APIs, Services over HTTP and so on.
  • Few assets, for example, SOAP APIs and REST APIs may not work after the custom domain change as the endpoints will change after the custom domain is configured, so you need to update the endpoints.
  • Configuration connectivity details of IBM webMethods Cloud Container will change after the custom domain is configured. Reconfigure the IBM webMethods Cloud Container settings to run the services, for example, Service Access Settings, Messaging Access Settings, API Details, CI/CD, and so on.
  • Reconfigure the IBM webMethods Cloud Container server settings to use the on-premises application.
