Redis on Render

This is an example repo with a Dockerfile for running a Redis cache with persistence as a private service on Render.

Render private services are only visible to other Render services in your account. They have internal URLs (e.g. redis:6379), can speak any protocol (like RESP), and can listen on any port.

Backing Redis with a disk makes it resilient to data loss in the case of restarts or deploys, and Render makes this easy to do with Render Disks.

Deployment

1. Select New Private Service on your Render dashboard and use your fork of this repo to create the service.

2. Make sure the Environment is set to Docker, and enter a name for the service (this will be used to generate the private URL).

3. Add a new disk in the Advanced section. Give it a name and set the mount path to /var/lib/redis. You can also change the default size for your disk: 1 GB should be enough for small projects.

Click Save and you're good to go! Once deployed, your Redis instance will be available on a URL similar to redis:10000, and you can start using your Redis URL from other services in your Render account.
