How it Works
The rolling update proceeds in a “make one, break one” process in order to maintain Service uptime and capacity.
- Start 1 new Process on the new Release
- Verify that the new Process passes a health check
- Stop 1 old Process that is running the old Release
- Repeat until all Processes are running the new Release
Any of these issues will appear in the logs that display during the promotion to help you determine what is going wrong.
