Redis Sentinel proper setup suggestions

[Wenkow]

Hi,

I am struggling with Redis Sentinel setup and distributed polling.

While setting the following variables inside the poller containers (flag SIDECAR_DISPATCHER=1) perfectly works

• REDIS_SENTINEL
• REDIS_SENTINEL_SERVICE
• REDIS_SENTINEL_PASSWORD
• REDIS_PASSWORD
• unset REDIS_HOST (this is handled by Sentinel service)

The same settings in main LibreNms container (no sidecar) does not work. The frontend doesn't come up. Error message is

In AbstractConnection.php line 131:

Connection refused [tcp://127.0.0.1:6379]  

so the main container is failing with the default settings. Looks like it does not pull the redis instance from Sentinel.

What is the correct setup I should provide the main container with? Does any real use case example exists?

Thank you for your feedback
