⁠Environment Variables (-e)

⁠Volume Mappings (-v)

⁠Application Setup

• Environment variables can also be passed in a file named env in the config directory. This file is sourced by the shell.
• Monit configuration is assembled from config files found in config/monit.d.
• If it does not exist, config/monit.d/http is used created to specify the port Monit listens on.
• If MMONIT_URL is passed in the environment, config/monit.d/mmonit is created using this variable as the parameter to a set mmonit directive.

⁠Local port

If the file config/monit.d/http is not present on startup, this file will be created with the following content

set httpd port 2812
    allow localhost
    allow ${NETWORK}/${NETMASK}

Where NETWORK and NETMASK are those of the container.

⁠M/Monit connection

If the environment variable MMONIT_URL is defined, the file config/monit.d/mmonit is created with the following content:

set monit ${MMONIT_URL}

⁠TODO

• Document configuration
• Document alpine monit version issues
