Issue

Steps to reproduce:

Trigger a deploy by pushing the code to the Staging or Production environment.

Expected behavior:

Deployment is successful.

Actual behavior:

The deployment is blocked and the following error message is displayed in the log:

Deploying applications Verifying configuration E: Error while verifying routes.yaml.
The following domains are configured for your cluster, but have no routes defined in your routes.yaml file:

- store1.example.com
- store2.example.com
- test-store.example.com

With your current routes.yaml configuration,
  these domains would NOT be served!

Cause

This error occurs if the route configuration for any additional domains that have been added to your project are missing from the routes.yaml file.

As part of the Adobe Commerce self-service enablement upgrade for self-service route configuration, we added a pre-deployment check to ensure that all domains in your project have routes configured in the routes.yaml file. If any domains are missing route configuration, the deployment gets blocked.

Solution

To resolve the blocked deployment, update the routes.yaml file to configure routes for the domains listed in the error message by using either of the following methods:

• Apply the patch supplied by Adobe Commerce during the upgrade process.
• Manually add the missing route configuration to the routes.yaml file.

Method 1: Apply the patch supplied by Adobe Commerce

1. Look for a recent Adobe Commerce support ticket with the title "Enable self service features for <project_ID>".
2. Follow the instructions in the ticket to apply the patch, which updates the route configuration for your cloud environment.
3. Сommit and push the changes to redeploy your project.

Method 2: Manually add the missing route configuration

1. To serve all domains in your project using the same route configuration, update the routes.yaml file adding route templates for the default domain and all other domains on your project as shown in the following example:

   "http://{default}/":
       type: upstream
       upstream: "mymagento:http"
   "http://{all}/":
       type: upstream
       upstream: "mymagento:http"
   

2. Сommit and push your changes to redeploy your project.
