docker pull tronyx/nagios
docker pull ghcr.io/tronyx/nagios| Branch | Image Tag | Notes |
|---|---|---|
| Master | latest | Master branch that is known to be stable. |
| Develop | develop | My testing/development branch for updates. |
| Ubuntu-22.04 | ubuntu-22.04 | Older Ubuntu base version that still has Python 2 and the plugins that require it. Use this for arm-v7 hardware. Will keep this as up-to-date as possible. |
Run the container with the example configuration using the following docker commands:
docker run --name nagios -p 8080:80 tronyx/nagios
docker run --name nagios -p 8080:80 ghcr.io/tronyx/nagiosAlternatively you can use external Nagios configuration & log data with the following docker commands:
docker run --name nagios \
-v /path-to-nagios/etc/:/opt/nagios/etc/ \
-v /path-to-nagios/var:/opt/nagios/var/ \
-v /path-to-custom-plugins:/opt/Custom-Nagios-Plugins \
-v /path-to-nagiosgraph-var:/opt/nagiosgraph/var \
-v /path-to-nagiosgraph-etc:/opt/nagiosgraph/etc \
-p 8080:80 tronyx/nagios
docker run --name nagios \
-v /path-to-nagios/etc/:/opt/nagios/etc/ \
-v /path-to-nagios/var:/opt/nagios/var/ \
-v /path-to-custom-plugins:/opt/Custom-Nagios-Plugins \
-v /path-to-nagiosgraph-var:/opt/nagiosgraph/var \
-v /path-to-nagiosgraph-etc:/opt/nagiosgraph/etc \
-p 8080:80 ghcr.io/tronyx/nagiosNote: The path for the custom plugins will be /opt/Custom-Nagios-Plugins, which you will need to reference in your configuration scripts.
There are a number of environment variables that you can use to adjust the behaviour of the container:
| Environment Variable | Description |
|---|---|
| MAIL_RELAY_HOST | Set Postfix relayhost |
| MAIL_INET_PROTOCOLS | Set the inet_protocols in Postfix |
| NAGIOS_FQDN | Set the server Fully Qualified Domain Name in Postfix |
| NAGIOS_TIMEZONE | Set the timezone of the server |
For the best results your Nagios container should have access to both IPv4 & IPv6 networks.
The default credentials for the web interface are:
| Username | Password |
|---|---|
nagiosadmin |
