Flux v0.41.1 is a patch release which extends the helm-controller's OOM watch feature introduced in v0.41.0 with support for automatic detection of cgroup v1 paths, and flags to configure alternative paths using --oom-watch-max-memory-path and --oom-watch-current-memory-path.
Flux v0.41.0 comes with new features and improvements. Users are encouraged to upgrade for the best experience.
Features and improvements
Experimental support of drift detection of Helm releases compared to cluster-state.
Improved handling of SIGTERM signals received by the helm-controller, which will now terminate running Helm install or upgrade actions, instead of potentially leaving them in a pending state.
Opt-in OOM watcher in helm-controller to handle graceful termination of the controller before it is forcefully killed by Kubernetes' OOM killer.
Kubernetes client and Custom Resource Definition life-cycle improvements to reduce the memory consumption of the helm-controller, with observed reductions up to 50%.
Opt-in allowance of DNS lookups during the rendering of Helm templates in the helm-controller via feature gate.
Optional disabling of the cache of the status poller used to determine the health of the resources applied by the kustomize-controller. This may improve memory usage on large scale clusters at the cost of more direct API calls.
Changes to the logging of all controllers to ensure Kubernetes components like the discovery client use the configured logging format.
New flux events command to display Kubernetes events for Flux resources, including the events of a referenced resource.
Custom annotations can now be set with flux push using --annotations.
