Run Valkey in Kubernetes

Valkey & Redis
1

Hi, I need some advice

I honestly haven’t googled yet, there are usually a lot of options out there, maybe someone has experience and will share the right solution right away.

In my application, I use Valkey as an intermediate fast storage of settings that are available to different services in the application. Roughly there are several different scripts and components that take settings from the Valkey database.

Right now I’m in the process of developing locally and using Docker-compose

version: '3.7'
services:

  valkey:
    image: valkey/valkey:8
    environment:
      - ALLOW_EMPTY_PASSWORD=yes
    ports:
      - "6379:6379"
    volumes:
      - valkey_data:/data

volumes:
  valkey_data:

Everything works great, I want to do the same thing in kubernetes cluster.

Perhaps someone has a simple path or YAML file to run Valkey in Kubernetes? So that other pods can connect to it without problems and password.

I don’t need multiple replicas or a complex configuration.

In general, for my project I built this manifest and it works fine.
