If I run a docker image and call
uptime, I always get a longer value than the real one.
docker run -it 1d2dfb3a35ab root@7efb3e947f73:/# uptime 23:41:57 up 16 min, 0 users, load average: 0.06, 0.02, 0.00
It hasn’t been running for 16 minutes, not even 16 seconds. =:-O
Is this a known issue or what?
The displayed uptime is that of the host. The kernel does not track uptime for individual containers in this way (though Docker does).
