Added

• Rollout deployment action chaosk8s.deployment.actions.rollout_deployment

Fixed

• Updated build/release to match newer Python packaging rules

0.26.3 - 2022-08-23

0.26.2 - 2022-03-30

Added

• Allow passing cmd as an array for exec_in_pods #127

0.26.0 - 2021-10-20

Fixed

• Fixed issue in replicaset.actions.delete_replica_set: 'ExtensionsV1beta1Api' object has no attribute 'list_namespaced_replica_set', we now use the AppsV1Api API

Removed

• Removed lots of duplicate tests which offered no different exercising of the code

Changed

• Log the path of the Kubernetes config file used, if found
• Client have logging at debug level with KUBERNETES_DEBUG

• Terminating pods now return the name of the pods that were actually deleted #104
• Deprecated chaosk8s.pod.actions.delete_pods in favor to chaosk8s.pod.actions.terminate_pods #122

0.24.0 - 2020-10-13

Changed

• Moved to stable API channel for deployment calls #103 as they beta channels have been deprecated for a while now.

Added

• Add namespace to all probes and actions with backward compatibility #39
• Added statefulset_is_fully_available and statefulset_is_not_fully_available #86.

Changed

• Fix call to delete_namespaced_pod so that the body argument is passed a named argument #34

0.19.1 - 2018-10-08

Changed

• As part of #21, we realized that passing None to some parameters of the Kubernetes client API was not the right move because, in that case, the client turns that into a "None" string which is not what we want. So I had to resort to many conditionals that make the code not as clean I'd want. Sigh!
