Andrei Dulvac commented on FELIX-5899:
--------------------------------------
[[email protected]], this sounds like a good extension to me. Since
we're on 0.X.Y, we shouldn't worry to much about changing the API - but maybe
it shows some future issues when we'd have to change it in the future.
> Add liveliness checks
> ---------------------
>
> Key: FELIX-5899
> URL: https://issues.apache.org/jira/browse/FELIX-5899
> Project: Felix
> Issue Type: Improvement
> Components: System Ready
> Affects Versions: systemready-0.2.0
> Reporter: Christian Schneider
> Assignee: Christian Schneider
> Priority: Major
> Fix For: systemready-0.4.0
>
>
> Felix systemready right now only supports readiness checks.
> In kubernetes there is a distinction between liveliness and readiness.
> * Liveliness decides if the pod needs to be killed and restarted.
> * Readiness decides if the pod is exposed to the service / load balancer.
> So it makes sense to also support liveliness checks in systemready.
> The design idea is that liveliness is a subset of readiness. So an inner set
> of checks should decide about liveliness and the full set should decide about
> readines.
> So I plan to add a property type=Readiness, Liveliness that determines the
> type of the check. A check without this property is considered as a readiness
> check.
> The second thing we need is another servlet that displays the liveliness
> status to the outside.
