ppittavi/ntpd repository overview

This container simply starts ntpd and expose 123/udp port

docker run -d ppittavi/ntpd -t ntpd

This statement creates a container named ntpd from the ppittavi/ntpd image and detached (-d) mode.

⁠Custom Configuration

The default configuration uses the /etc/ntpd.conf file with a standard debian config file . For custom configuration purposes the /etc/ntpd.conf file needs to be replaced by a specific volume mapping. For example the -v <<PATH_TO_MY_NTPD_CONF>>/ntpd.conf:/etc/ntpd.conf flag can be used in the run statement.

Example: running ntpd server mapping 123 udp port with config file located in /docker/ntpd/ntpd.conf

 docker run -d --cap-add SYS_RESOURCE --cap-add SYS_TIME --publish 123:123/udp --rm --name ntpd --volume /docker/ntpd/ntp.conf:/etc/ntp.conf  ppittavi/ntpd
