Custom hostname
Before making your application available to users in your Production environment, you may want to change the URL from your-organization-name.grexx.today to something specific (such as app.example.com). You can do this by setting a custom hostname for the relevant DTAP environment.
You must have access to the DNS settings for the domain you want to use (in this example, for example.com). You will also need to allow time for your request to be processed by the Grexx service desk.
DNS change
First you need to update the DNS entry for your domain. For the hostname you want to use, change the DNS entry to a CNAME record pointing to platform.in.traffic.grexx.io. For example, the DNS entry for app.example.com would be:
app.example.com. CNAME platform.in.traffic.grexx.io.
Syntax might differ depending on the DNS service you're using.
SSL certificate
When the DNS has been changed, your hostname (app.example.com) points to the Grexx Platform. It then lands on our load balancers, where it needs a valid SSL certificate. We can offer you a free Letsencrypt certificate, or you can supply your own certificate.
In either case, you will need to contact the Grexx service desk to have the certificate installed or generated. Contact your Grexx Coach for details.
If you are supplying your own certificate, you can start this process before making the DNS change. If you would like to use a free Letsencrypt certificate, you must make the DNS change first.
Hostname in the Grexx Platform
Once the DNS change and SSL certificate have been configured, you need to specify the DTAP environment you want to serve when a user visits your hostname. Open My Grexx and under Settings specify the hostname for the relevant environment(s).
