Docker Compose Icinga stack

Quelle: https://github.com/lippserd/docker-compose-icinga

Stack nach Anleitung von Github herunterladen und im Verzeichnis folgende Änderungen vornehmen:

  1. Eingebaute Host-Konfiguration entfernen (wird dann im Director konfiguriert)
    Datei /etc/icinga2/conf.d/hosts.conf löschen lassen
    in Datei init-icinga2.sh unten einfügen 
    if [ -f /data/etc/icinga2/conf.d/hosts.conf ]; then
    rm -F /data/etc/icinga2/conf.d/hosts.conf
fi
  2. Passwort von „icingaadmin“ ändern
    in Datei docker-compose.yml die Zeile icingaweb.passwords.icingaweb2.icingaadmin:
  3. Icinga Stack starten 
    cd /opt/docker-compose-icinga
docker compose up -d
  4. Icinga Stack stoppen 
    docker compose down
  5. Wiederherstellen der Standard-Benutzerrollen unterbinden
    in Datei docker-compose.yml die Zeilen auskommentieren
    icingaweb.roles.Administrators.groups: Administrators
    icingaweb.roles.Administrators.permissions: '*'
    icingaweb.roles.Administrators.users: icingaadmin
  6. Icinga Stack starten 
    docker compose up -d
  7. Icinga nach reboot automatisch starten systemctl edit –full docker-compose-icinga.service 
    Unit]
Description=Start Icinga-Playground Docker containers
After=docker.service
Requires=docker.service

[Service]
Type=oneshot
RemainAfterExit=yes
WorkingDirectory=/opt/docker-compose-icinga
User=linux
Group=docker
#ExecStart=docker compose -p icinga-playground up -d
#ExecStop=docker compose -p icinga-playground stop
ExecStart=docker compose up -d
ExecStop=docker compose stop
TimeoutStartSec=0

[Install]
WantedBy=multi-user.target

    Danach den Service einschalten und den Systemd-Daemon neustarten systemctl enable docker-compose-icinga.service && systemctl daemon-reload

Eigene Checks einbinden

In den Icinga2 Container verbinden und folgendes ausführen: 

echo "include_recursive \"/custom_data/custom.conf.d/\"" >> /etc/icinga2/icinga2.conf

Danach auf dem Docker-Host den Ordner für die eigenen Checks erstellen und Checks dort ablegen. 

mkdir -p /opt/docker-compose-icinga/icinga2.conf.d/my-plugins/

Hier ein Check zum Überwachen von QNap-NAS (Quelle: siehe Inhalt):

Eigene Icinga-Constants erstellen. 

vi /opt/docker-compose-icinga/icinga2.conf.d/constants.conf

Inhalt: 

# My Custom Plugins
const CustomPluginDir = "custom_data/custom.conf.d/my-plugins/"

Eigene Icinga-Service Konfiguration erstellen. 

/opt/docker-compose-icinga/icinga2.conf.d/services.conf

Inhalt am Beispiel vom Check für QNap-Nas: 

object CheckCommand "check_qnap2" {
  import "plugin-check-command"
  command = [ CustomPluginDir + "/check_qnap2.sh" ]
  arguments += {
        "-H" = {
            description = "Host name, IP Address, or unix socket (must be an absolute path)"
            value = "$qnap_address$"
        }
        "-C" = {
            description = "Community string for SNMP communication (default is 'public')"
            value = "$qnap_community$"
        }
        "-v" = {
            description = "SNMP protocol version (defalt: 2c)"
            value = "$qnap_version$"
        }
        "-p" = {
            description = "Port number (default: 161)"
            value = "$qnap_port$"
        }
        "-t" = {
            description = "Seconds before connection times out (default: 10)"
            value = "$qnap_timeout$"
        }
        "-a" = {
            description = "Executed Command-Check"
            value = "$qnap_argument$"
        }
  }
  vars.check_address = {
        arguments = [  ]
        deprecated = false
        name = "<anonymous>"
        side_effect_free = false
        type = "Function"
    }
    vars.check_ipv4 = false
    vars.check_ipv6 = false
    vars.qnap_address = "$check_address$"
}

Nun noch den Icinga stack neu starten. 

cd /opt/docker-compose-icinga
docker compose restart

Jetzt kann der neu definierte Check im Director normal verwendet werden.
