Run nagrestconf in a docker container.
Two containers are created here, mclarkson/nagrestconf and mclarkson/nagrestconf-restarter.
Use with a compatible nagios container such as QuantumObject/docker-nagios or JasonRivers/Docker-Nagios.
Start the Nagios 4.x container (See JasonRivers/Docker-Nagios):
docker run -d --name nagios4 -p 8080:80 -v /opt/nagios jasonrivers/nagios:latest
Start the nagrestconf container:
wget https://raw.githubusercontent.com/mclarkson/nagrestconf-docker/master/jasonrivers_docker-nagios.env
docker run -d -p 8880:8080 --name nagrestconf -v /tmp \
--volumes-from nagios4 --env-file jasonrivers_docker-nagios.env \
mclarkson/nagrestconf
Finally start the restart container:
docker run -d --name nagrestconf-restarter \
-e NAGIOSCMD=/opt/nagios/var/rw/nagios.cmd \
--volumes-from nagrestconf mclarkson/nagrestconf-restarter
With the above setup:
- Nagios is at http://localhost:8080/nagios
Default credentials: nagiosadmin / nagios - Nagrestconf is at http://localhost:8880/nagrestconf
Default credentials: nagrestconfadmin / admin
To change the nagrestconf default password:
docker exec -it nagrestconf /bin/bash
htpasswd -c /etc/nagrestconf/nagrestconf.users nagrestconfadmin
exit
QuantumObject/docker-nagios has gone! - leaving this section here in case it returns
QuantumObject/docker-nagios has returned!
Start the Nagios 4.x container ( See QuantumObject/docker-nagios):
docker run -d --name nagios -v /usr/local/nagios -p 25 -p 8080:80 quantumobject/docker-nagios
docker exec -it nagios /bin/bash
htpasswd /usr/local/nagios/etc/htpasswd.users nagiosadmin
exit
Start the nagrestconf container:
wget https://raw.githubusercontent.com/mclarkson/nagrestconf-docker/master/quantumobject_docker-nagios.env
docker run -d -p 8880:8080 --name nagrestconf -v /tmp \
--volumes-from nagios --env-file quantumobject_docker-nagios.env \
mclarkson/nagrestconf
Finally start the restart container:
docker run -d --name nagrestconf-restarter --volumes-from nagrestconf mclarkson/nagrestconf-restarter
With the above setup:
- Nagios is at http://localhost:8080/nagios
- Nagrestconf is at http://localhost:8880/nagrestconf
Default credentials: nagrestconfadmin / admin
To change the nagrestconf default password:
docker exec -it nagrestconf /bin/bash
htpasswd -c /etc/nagrestconf/nagrestconf.users nagrestconfadmin
exit
Create the pod:
kubectl apply -f https://raw.githubusercontent.com/mclarkson/nagrestconf-docker/master/kubernetes/nagios-nagrestconf-allinone.yml
Get a console on the nagios container:
name=$(kubectl get pods -l app=nagrestconf -o jsonpath="{.items[0].metadata.name}")
kubectl exec -ti $name -c nagios bash
Set the password:
htpasswd /usr/local/nagios/etc/htpasswd.users nagiosadmin
exit
Use port-forward to test:
kubectl port-forward $name 8080:80 8880:8080
With the above setup:
- Nagios is at http://localhost:8080/nagios
- Nagrestconf is at http://localhost:8880/nagrestconf
Default credentials: nagrestconfadmin / admin
Take a look in the kubernetes/ directory to see service and ingress yaml examples.
