Describe the enhancement
Add a flag in registration controller that sets leaseDurationSeconds for ManagedCluster

[qiujian16]

it could be set in the managedCluster, what you mean is the defaultLeaseDurationSeconds set at the init time, right?

User can still change this afterwards

[dongbeiqing91]

It's about how the release system deals with this.
If leaseDurationSeconds can be set by the registration controller, the release system only has to apply pure specs.
If it needs to be updated afterwards, an extra job is needed.
In Cloud world, the first method is preferred.

[qiujian16]

so it can be regarded as a default leaseDurationSection for all managedcluster, right?

[dongbeiqing91]

Yes I think so. But anyway, it's nice to have, not a must have.
