This repository is used as source for the
docker image icinga/icinga2 located at Docker Hub.
- Docker >= 1.6.0
This container is used for demos, tests and development only.
If you encounter bugs, please open a new issue at https://github.com/icinga/docker-icinga2 and/or send a PR.
- Based on centos:centos7 (similar to the Vagrant boxes)
- Icinga 2 w/ DB IDO MySQL, Icinga Web 2, MariaDB, Apache2
- Icinga 2 API
- Default installation/credentials. Use at your own risk.
Start a new container, bind the container's port 80 to localhost:3080 and let the initialization do its job:
$ docker run -ti --name icinga2 -p 3080:80 icinga/icinga2
If you want to invoke it manually, go for
$ docker run -ti --name icinga2 -p 3080:80 icinga/icinga2 /bin/bash
# /opt/icinga2/initdocker
Attach to a running container using exec and the container name.
$ docker exec -ti icinga2 /bin/bash
$ docker stop icinga2
$ docker rm icinga2
Build a new container based on this repository:
$ sudo docker pull centos:centos7
$ sudo docker build -t icinga/icinga2 .
Even if you can already mount specific volumes there's ssh access available. Make sure to map the port accordingly.
$ sudo docker run -ti --name icinga2 -p 3080:80 -p 3022:22 icinga/icinga2
Then login as appuser/appuser. sudo is enabled for this user.
$ ssh appuser@localhost -p 3022
The configuration is located in /etc/icinga2 which is exposed as volume from docker.
By default the icinga database is created, and ido-mysql and command features
are enabled.
The container startup will validate the configuration once (e.g. if you have mounted the volume).
The container already enables the Icinga 2 API listening on port 5665. Export the
port accordingly.
docker run -d -ti --name icinga2-api -p 4080:80 -p 4665:5665 icinga/icinga2
After the container is up and running, connect via HTTP to the exposed port using
the credentials root:icinga.
Example for Docker on OSX (change the IP address to your localhost):
curl -k -s -u root:icinga 'https://192.168.99.100:4665/v1/objects/hosts' | python -m json.tool
In order to enable the Graphite feature at runtime (e.g. exposing port 2003 for a separate container
running Graphite) you'll need to pass the environment variables to the container.
| Environment Variable | Description |
|---|---|
| ICINGA2_FEATURE_GRAPHITE | Enables the Graphite feature |
| ICINGA2_FEATURE_GRAPHITE_HOST | Required. Host where Graphite is running on. |
| ICINGA2_FEATURE_GRAPHITE_PORT | Required. Port where Graphite is listening on. |
Furthermore you'll need to --link the container to an existing container, e.g. graphite to allow
the link on port 2003 required by Graphite.
docker run -d -ti --name icinga2 -p 3080:80 --link graphite:graphite -e ICINGA2_FEATURE_GRAPHITE=1 -e ICINGA2_FEATURE_GRAPHITE_HOST="192.168.99.100" -e ICINGA2_FEATURE_GRAPHITE_PORT=2003 icinga/icinga2
Example for a Graphite container called graphite:
docker run -d --name graphite --restart=always -p 9090:80 -p 2003:2003 hopsoft/graphite-statsd
Icinga Web 2 can be accessed at http://localhost:3080/icingaweb2 w/ icingaadmin:icinga as credentials.
The configuration is located in /etc/icingaweb2 which is exposed as volume from docker.
By default the icingaweb2 database is created including the icingaadmin user. Additional
configuration is also added to skip the setup wizard.
The following ports are exposed:
| Port | Service |
|---|---|
| 22 | SSH |
| 80 | HTTP |
| 443 | HTTPS |
| 3306 | MySQL |
| 5665 | Icinga 2 API & Cluster |
These volumes can be mounted in order to test and develop various stuff.
