第 7 章 Responsive restarts and security certificates

MicroShift depends on device IP addresses and system-wide clock settings to remain consistent during its runtime. However, these settings may occasionally change on edge devices, such as DHCP or Network Time Protocol (NTP) updates.

When such changes occur, some MicroShift components may stop functioning properly. To mitigate this situation, MicroShift monitors the IP address and system time and restarts if either setting change is detected.

The threshold for clock changes is a time adjustment of greater than 10 seconds in either direction. Smaller drifts on regular time adjustments performed by the Network Time Protocol (NTP) service do not cause a restart.
