Critical Issues after installation

How can we solve this critical issues?

Hi, these checks come from the default configuration provided by icinga in the /etc/icinga2/conf.d/host.conf file, therefore they are just example and are not intended to be used as relevant checks. Specifically, in a docker container they are irrelevant since they are trying to curl localhost:80.

docker exec -it "cb4bc8a557ad" /bin/bash
icinga@cb4bc8a557ad:/$ curl localhost:80
curl: (7) Failed to connect to localhost port 80: Connection refused

Though if you want to get rid of these checks you have two options :

• delete the /etc/icinga2/conf.d/hosts.conf by adding this block to the init-icinga2.sh file :

if [ -f /data/etc/icinga2/conf.d/hosts.conf ]; then
    rm -F /data/etc/icinga2/conf.d/hosts.conf
fi

• or add a check that is supposed to always work :

if [ -f /data/etc/icinga2/conf.d/hosts.conf ]; then
    sed -i "s/127.0.0.1/8.8.8.8/" /data/etc/icinga2/conf.d/hosts.conf
fi

When we take this issue as one of many issues about the default configuration here - we could also think about changing the default configuration within the init scripts by default.

In my eyes

• I would remove that default host, because the process runs within a docker container and 127.0.0.1 is not a host. When we think, that users of this project would use the director it's better to remove this static entry.
• also there are several default service assignments in the default configuration (services.conf) which will apply by default to all new entries.

Of course a user of this service should know a bit about how to configure icinga, but we could at least release an intial version that doesnt run into failure because of the mixture of docker and host. The project knows, that the icinga services run in a docker environment and could create it's own default docker compatible configuration.

Are there other issues known to this specific problem?

I found only one, that has something to do with check_http and verify-host - the switch is not available in the integrated plugin for example.
