Sitecore Docker Containers — Auto Bind Custom Domains to your CM and CD

If you’re developing with Sitecore on Docker and need to bind some custom domains to your CM/CD instances in Traefik, here’s an easy and future-proof way.

Naming Convention

First, I’m defining that cm.yourdomain.localhost and *-cm.yourdomain.localhost should automatically resolve to your CM container, and similarly cd.yourdomain.localhost and *-cd.yourdomain.localhost should automatically resolve to your CD container.

Update docker-compose.yml

Locate your traefik.http.routers.cm-secure.rule and traefik.http.routers.cd-secure.rule.

Update traefik.http.routers.cd-secure.rule as follows:

“traefik.http.routers.cd-secure.rule=HostRegexp(`{subdomain:([a-z]+-|)}${CD_HOST}`)”

Update traefik.http.routers.cm-secure.rule as follows:

“traefik.http.routers.cm-secure.rule=HostRegexp(`{subdomain:([a-z]+-|)}${CM_HOST}`)”

Update your init.ps1

Add your custom domains. For example:

Add-HostsEntry “custom1-cm.$($HostName).localhost”

Add-HostsEntry “custom1-cd.$($HostName).localhost”

Update <sites> configuration

If you’re not on SXA then update your <sites>, if you’re on SXA then update the Site Groupings.

Done!
