Correct way to disable updates
Hi, I am using kubernetes with CoreOS. I have read the documentation but still some doubts about the correct way of documentation.
I am using etcd and want to be in safe in case a reboot. At the same time I want to disable updates too. Since I am very often creating our infrastructure from bottom up, I want an immutable infrastructure instead of updating it.
What I understood is that in order to have a healthy reboot I need:
reboot_strategy: etcd-lock
and in order to disable updates I need:
- name: update-engine.service
mask: true
If my approach is true, It would be nice to add a documentation to make it clear.
What do you think?
For me this is unclear as as well. cloud-config docs refer to a differently named key reboot-strategy.
relevant discussion is at here: https://github.com/coreos/bugs/issues/1982
Current state is buggy, waiting someone to be clear the situation.
The correct way to do this is to use Ignition to mask both locksmith and update engine. I realize that in your case, @cemo, you are unable to use Ignition.
