-d ethnchao/nagios In some features, such as using the Adagios - Okconfig - Install Agent, you need to configure the NRDP server address in the remote client. The IP + port of the address is also the address of the Nagios server, but when you use the Docker to run the container, Nagios Do not know what their own server address, so when we run the container, passing the server address to it.

$ docker run --name nagios -p 9001:80 -p 3000:3000 -d ethnchao/nagios --server-url http://172.17.242.190:9001⁠ You can choose to mount additional configuration files, plugin, okconfig-example to the container, such as the additional configuration file on /data/conf, plugin on /data/plugin, okconfig-example on /data/example.

$ docker run --name nagios -p 80:80 -p 3000:3000
-v /data/conf:/usr/local/nagios/etc/mount
-v /data/plugin:/data/plugin
-v /data/example:/data/example
-d ethnchao/nagios If you need to store the monitoring information to the MySQL database, you need to enable Ndoutils, which there are two cases：

If you already executed the Ndoutils database initialization script in the MySQL database, then run this container with option: --enable-ndo. $ docker run --name nagios -p 80:80 -p 3000:3000
-e MYSQL_USER=nagios -e MYSQL_PASSWORD=nagios
-e MYSQL_ADDRESS=172.17.242.178 -e MYSQL_DATABASE=nagios
-d ethnchao/nagios --enable-ndo If you did not execute the Ndoutils initalization script in the MySQL database, you can run this container with option: --enable-ndo --create-db $ docker run --name nagios -p 80:80 -p 3000:3000
-e MYSQL_USER=nagios -e MYSQL_PASSWORD=nagios
-e MYSQL_ADDRESS=172.17.242.178 -e MYSQL_DATABASE=nagios
-d ethnchao/nagios --enable-ndo --create-db Finally we recommend using docker-compose to run Nagios with MySQL containers, check this docker-compose.yml 。
