Connection icinga2, icingaweb2 and icingadb (redis?)

I cannot make icingadb work in a new environment and need some help. I do not have any experience with icingadb, have been using IDO until now.

Main issue:

The message above in red indicates that there is some communication error with Redis, since Icinga2 is talking to Redis only and IcingaWeb2 is talking to Redis and MariaDB (Right?).
Redis and Mariadb are talking to IcingaDB, Icinga2 and IcingaWeb2 are not, right?)

Goal is to have as much services as possible running in containers. We are on RHEL 8 and therefore using rootless Podman. I was following this information:

Docker IcingaDB
and

I interpret this information as:
Icinga2 (icingadb feature) → Redis
IcingaWeb2 (icingadb module) → Redis

I set up the following containers:

CONTAINER ID  IMAGE                               COMMAND               CREATED       STATUS           PORTS                   NAMES

So, that means:
Icinga2: local install (eventhandlers, scripts etc)
IcingaWeb2: Container
IcingaDB: Container
Mariadb for IcingaDB: Container
Redis: Container

To investigate communication to Redis, I checked logs:
Icinga2 Log:

information/IcingaDB: 'icingadb' started.
information/IcingaDB: Trying to connect to Redis server (async) on host 'localhost:6379'
information/IcingaDB: Connected to Redis server

IcingaWeb2 (where to find a good log?)

So, that tells me that both Icinga2 and IcingaWeb2 are connecting to Redis. Right? Is there anything else to install for IcingaDB next to Icinga2 on that host?

  • Icinga DB Web version (System - About): I do not understand. There are the module and the feature. Anything else?
  • Icinga Web 2 version (System - About): 2.11.1 (podman rootless)
  • Web browser: Edge
  • Icinga 2 version (icinga2 --version): 2.12.4-1
  • Icinga DB version (icingadb --version): localhost/icinga/icingadb 1.0.0
  • PHP version used (php --version): -
  • Server operating system and version: RHEL 8.6

Hi @danielbierstedt, you’re using incompatible versions of Icinga DB and Icinga 2. When using Icinga DB v1.0.0, you also need at least 2.13.4 Icinga 2 version.

You are correct. After pulling the most recent containers, connection works. Thank You!
