How to disable caching on Pi-hole v6 container

Help
1

I've just upgraded my Pi-Hole container to the latest version and I was wondering if there's a way to disable caching like with the CUSTOM_CACHE_SIZE environment variable that we could use on v5, without the need to rebuild a custom Pi-hole image or changing the cache size to zero from GUI.

Notice that the link to "DNS Cache Documentation", i.e. DNS cache - Pi-hole documentation, present in System Settings -> DNS Cache Metrics is not working

Thanks in advance for any help.

As you are already aware of how to change dns.cache.size via Pi-hole's All settings » DNS UI pane, you also already have the correct option name.

As mentioned in Introducing Pi-hole v6, Pi-hole's consolidated pihole.toml configuration file is not only richly commented, but can also be edited in a variety of ways:

  • Directly editing the toml file
  • Via the command line, e.g pihole-FTL --config dns.cache.size 0
  • Using the API
  • Via the web interface (which uses the API :wink:)
  • Via environment variables named, e.g FTLCONF_dns_cache_size=0

I've substituted the original examples with your sought option above, to better demonstrate how to apply a known option name. :wink:

Thank you very much for the quick reply! It was so easy, shame on me for not reading carefully the available dock on docker hub :frowning:
