What ExtendedDaemonSet is

ExtendedDaemonSet is a free, self-hosted Kubernetes controller for canary deployments and custom rolling updates of DaemonSets. It can release a new version to a configured number of pods or nodes before continuing across the deployment. Canary controls include replica count, duration, automatic pausing, restart thresholds, and automatic or manual validation. Kubernetes custom resources cover ExtendedDaemonSet deployments, replica sets, and settings. Resource settings can be overridden for label-selected nodes, while node annotations can also change container resources and node affinity can keep a pod away from a node. Installation uses Kustomize manifests or the Datadog Helm chart. The kubectl-eds plugin lets operators inspect deployments and pods, then validate, pause, resume, or fail canary releases. The README documents moving an existing DaemonSet under the controller while recognizing current pods. By default, it watches resources only in its own namespace; cluster-wide watching requires configuration. The project requires a Kubernetes cluster and is licensed under Apache License 2.0. Its repository was archived on September 18, 2026, and is no longer maintained or supported.

Who it suits

ExtendedDaemonSet suits Kubernetes operators who need staged DaemonSet rollouts and node-specific resource controls. It is relevant for self-hosted environments that can accept an archived, unsupported project.

What it does well

Canary rollout controls and validation
Custom rolling update behavior
Node-specific resource overrides
Kustomize and Helm installation
kubectl plugin for rollout management

What to know first

Repository archived September 18, 2026
No new features, fixes, or support
Requires a Kubernetes cluster
Namespace watching is limited by default

Limits

By default, the controller watches ExtendedDaemonSet resources only in its own namespace; cluster-wide watching requires configuration. The repository is archived and receives no new features, fixes, or support.

Getting started

Open the ExtendedDaemonSet repository website
Prepare a Kubernetes cluster with several nodes
Install the controller with Kustomize manifests or the Datadog Helm chart
Create the project’s Kubernetes custom resources
Use kubectl-eds to inspect deployments and manage canary validation

Verdict

ExtendedDaemonSet provides detailed canary and rolling-update controls for Kubernetes DaemonSets at no charge. Its archived status and lack of maintenance are major considerations before adoption.

Questions
