routerology/ntp repository overview

⁠NTP Enabled Container

⁠This is a Chrony implementation in docker container, that you can use for all your NTP needs

If you are interested, there is also a git repository that you can use to build your own container:

github.com/whadafunk/contimer.git⁠

The base distro used for this is Alpine Linux. When I started this I wanted to go for ntpd, but it seems that ntpd is not so much supported anymore by the popular distros, and Chrony has better performance overall. So there it is, NTP with chrony.

⁠Using the container

docker container run -d --rm --network bridge --name ntp -p 123:123/udp contimer

I have exposed port 123/udp and port 323/udp in the Dockerfile, but that might not help you so much because if you are using -P, docker will chose random high ports on the local host

docker container run -d --rm --network bridge --name ntp2 -P routerology/ntp
