How to make sure docker's time syncs with that of the host?
docker, ntp
Solution
The source for this answer is the comment to the answer at: Will docker container auto sync time with the host machine?
After looking at the answer, I realized that there is no way a clock drift will occur on the docker container. Docker uses the same clock as the host and the docker cannot change it. It means that doing an `ntpdate` inside the docker does not work.
The correct thing to do is to update the host time using `ntpdate`
As far as syncing timezones is concerned, `-v /etc/localtime:/etc/localtime:ro` works.
Problem
I have dockers running on Linode servers. At times, I see that the time is not right on the dockers. Currently I have changed the run script in every docker to include the following lines of code. ``` yum install -y ntp service ntpd stop ntpdate pool.ntp.org ``` What I would ideally like to do however is that the docker should sync time with the host. Is there a way to do this?
