CACHE_ENABLED="false" is not respected when CACHE_STORE="redis"

[rc1]

Preflight Checklist

Describe the Bug

I was following the docker installation guide by using the docker compose example.

However, I didn't want to use Redis. I removed the redis container and set the CACHE_ENABLED: 'false'.

The guide states:

      CACHE_ENABLED: 'true'
      CACHE_STORE: 'redis'
      CACHE_REDIS: 'redis://cache:6379'

But I changes this to

      CACHE_ENABLED: 'false' # changes here
      CACHE_STORE: 'redis'
      CACHE_REDIS: 'redis://cache:6379'

On running the compose file, errors about the cache were presented.

To Reproduce

Copy the docker compose example from here.

Comment out these lines:

  cache:
    container_name: cache
    image: redis:6
    networks:
      - directus

Set this environment variable to 'false':

CACHE_ENABLED: 'true'

Errors Shown

[cache] Error: getaddrinfo ENOTFOUND cache

Can you try it with

 CACHE_ENABLED: false

instead of

 CACHE_ENABLED: 'false'

?

[rijkvanzanten]

I believe this is a configuration problem, rather than a bug. The system cache will also rely on the configured cache driver, so make sure to set CACHE_SCHEMA=false
CACHE_PERMISSIONS=false as well as CACHE_ENABLED=false if you want to disable all caches 👍🏻

It would be helpful if the guide used

=true

Instead of

='true'

So to prevent people getting tripped up like myself.

Minor nit on a great system, thanks.

Those two should be parsed the same in directus' env var casting 👍🏻 I believe my other comment is the source of your confusion 🙂

The redis cache should be updated when something gets added /deleted

The redis cache should be updated when something gets added /deleted

This behavior can be enabled via the CACHE_AUTO_PURGE environment variable 🙂 Link to docs: https://docs.directus.io/self-hosted/config-options.html#cache
