Icinga Web 2

Icinga Web 2 can be accessed at http://localhost/icingaweb2 with the credentials icingaadmin:icinga

Graphite

The graphite writer can be enabled by setting the ICINGA2_FEATURE_GRAPHITE variable to true or 1 and also supplying values for ICINGA2_FEATURE_GRAPHITE_HOST and ICINGA2_FEATURE_GRAPHITE_PORT. This container does not have graphite and the carbon daemons installed so ICINGA2_FEATURE_GRAPHITE_HOST should not be set to localhost.

Example:

sudo docker run -e --link graphite:graphite -e ICINGA2_FEATURE_GRAPHITE=true -e ICINGA2_FEATURE_GRAPHITE_HOST=graphite -e ICINGA2_FEATURE_GRAPHITE_PORT=2003 -t jordan/icinga2:latest

Icinga Director

The Icinga Director Icinga Web 2 module is installed and enabled by default. You can disable the automatic kickstart when the container starts by setting the DIRECTOR_KICKSTART variable to false. To customize the kickstart settings, modify the /etc/icingaweb2/modules/director/kickstart.ini
