CouchbaseCluster Events
Kubernetes events that are raised by the Operator for CouchbaseCluster resources.
Kubernetes can displays extended information about a resource using the kubectl describe command.
The Operator generated life-cycle events as the cluster is provisioned, edited or repaired.
These events may be used for problem determination or as synchronous triggers for external Kubernetes orchestration.
The lifecycle of a CouchbaseCluster includes the following events (in no particular order):
Member Lifecycle
- MemberCreationFailed
-
A new member was unable to be created. This may be due to pod scheduling constraints, network issues or TLS configuration.
- NewMemberAdded
-
A new Couchbase node was added to the cluster.
- FailedAddNode
-
A Couchbase node failed to join the cluster.
- FailedAddBackNode
-
A Couchbase node failed to be added back into a cluster after being manually failed over.
- MemberRemoved
-
A Couchbase node was removed from the cluster.
- MemberDown
-
A Couchbase node has been reported as down by its peers.
- MemberRecovered
-
A failed Couchbase node has been recovered from its persistent volume.
- MemberFailedOver
-
A node has either been failed over automatically or manually.
- RebalanceStarted
-
A rebalance operation has started.
- RebalanceIncomplete
-
A rebalance operation has terminated abnormally; nodes may have not been added or ejected as expected.
- RebalanceCompleted
-
A rebalance operation has successfully completed.
- ExpandVolumeSucceeded
-
A volume expansion operation has successfully completed.
- ExpandVolumeFallback
-
A volume expansion operation has failed and the cluster is falling back to a rolling upgrade of volumes.
- ExpandVolumeStarted
-
A volume expansion operation has started.
- ReconciliationFailed
-
A reconciliation operation failed. This may be due to a transient error or a configuration issue.
Cluster Upgrade Lifecycle
- UpgradeStarted
-
An upgrade operation has started.
- UpgradeFinished
-
An upgrade operation has successfully completed.
Upgrade events are raised in relation to an upgrade of the entire cluster and not individual nodes.
Individual node upgrades will raise NewMemberAdded, RebalanceStarted, MemberRemoved and RebalanceCompleted member lifecycle events as members are swapped out for upgraded replacements.
