kubesleep

README

Merge semantics:

The kubesleep suspend operation can be repeared to handle e.g.:

• Resume a previously cancelled suspend operation.
• Retry a failed suspend operation.
• Redo a suspend operation after adding or modifying the namespace with e.g. kubectl or helm.

New workloads will be added to the suspend state. Manually changing the replicaCount of a workload won't be integrated into the suspend state. The wake operation will always restore initial state of a workload and not an intermediate state. A successful wake operation will reset the suspend state. (the statefile ConfigMap is deleted)

An example:

You suspend scales a workload down from 2 to 0 You manually scale it back up to 5 using e.g. kubectl edit You suspend the namespace again. You wake the namespace back up. The workload will get scaled to the initial value up to 2, not to the intermediate value of 5

Limitations

Executing multiple suspend or wake operations on the same namespace can lead to unexpected errors and is not supported. In the future this may become explicitly prevented.
