Example 16 with Lease

use of com.palantir.lock.v2.Lease in project kubernetes-client by fabric8io.

the class LeaseLockTest method getWithExistingLeaseShouldReturnLeaderElectionRecord.

Example 17 with Lease

use of com.palantir.lock.v2.Lease in project kubernetes-client by fabric8io.

the class LeaseLock method update.
