Summary

The Kener template appears to start successfully at first, but then crashes because REDIS_URL is not defined.

The template configures SQLite, runs migrations and seed successfully, and prints Kener is running on port 3000!. Immediately after that, the process exits with a Redis-related error.

Node.js v24.17.0

Expected behavior

The Kener template should start successfully using the default template configuration.

Actual behavior

The application exits during startup because REDIS_URL is missing.

Possible fix

The Kener template may need one of the following:

  • Include a Redis service in the template and set REDIS_URL automatically.
  • Add REDIS_URL to the required environment variables for the template.
  • If Redis is optional for Kener, configure the template so that the queue/Redis integration is disabled unless Redis is provided.

Notes

The database appears to be configured as SQLite and migrations/seed complete successfully, so this seems specifically related to the missing Redis configuration rather than the database setup.

@dosubot[bot] commented on GitHub (Jul 7, 2026):

I can confirm this is a valid issue. The Kener template's docker-compose.yml does not include a Redis service and does not define a REDIS_URL environment variable [1]. The template only provides SQLite (default), PostgreSQL, and MySQL as database options.

It appears that a newer version of the rajnandan1/kener:latest image now requires Redis for its queue/job system, but the template hasn't been updated to account for this dependency.

A fix would likely involve:

  1. Adding a Redis service to the docker-compose (e.g., redis:alpine)
  2. Setting REDIS_URL (e.g., redis://redis:6379) in the Kener service's environment variables
