You can find the Docker Hub Registry HERE or the GitHub Registry HERE.

• Nagios configuration is stored in the /opt/nagios/etc directory.
• NagiosGraph configuration is stored in the /opt/nagiosgraph/etc directory.
• NSCA configuration is stored in the /opt/nagios/etc directory.

docker pull tronyx/nagios
docker pull ghcr.io/tronyx/nagios

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/nagios

Alternatively 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/nagios

Note: 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:

For the best results your Nagios container should have access to both IPv4 & IPv6 networks.

The default credentials for the web interface are:
