Argo Rollouts is a Kubernetes controller that brings advanced progressive delivery capabilities—like blue-green and canary deployments with automated analysis—to cloud-native teams. It leverages ingress controllers and service meshes to gradually shift traffic to new versions, and can query metrics from providers like Prometheus or Kayenta to automatically promote or rollback deployments. This makes Argo Rollouts a powerful tool for reducing release risk and improving deployment control, enabling features such as fine-grained traffic splitting and automated rollback on failures.

However, for teams managing Argo Rollouts on their own (in self-managed clusters or on-premises), maintaining and upgrading it can be full of challenges. In this post, we’ll show how Chkk’s Operational Safety Platform offers an end-to-end solution for managing these upgrades. From curated release notes and preflight checks to structured Upgrade Templates and preverification, Chkk helps you confidently upgrade Argo Rollouts without the risk of unpredictable deployment failures or downtime.

Chkk’s Coverage for Argo Rollouts

Curated Release Notes

Chkk continuously monitors Argo Rollouts' upstream release notes, filtering out the noise and providing concise summaries of critical updates, such as new progressive delivery capabilities, important bug fixes, and deprecated APIs. This ensures teams remain informed about significant changes well in advance, preventing unexpected disruptions. Chkk highlights updates like the introduction of new plugin systems for canary deployments or fixes for issues that could cause rollouts to stall or fail unexpectedly.

Preflight & Postflight Checks

Before initiating an upgrade, Chkk conducts detailed preflight checks, validating that your environment is compatible with the new Argo Rollouts version. This includes identifying deprecated configuration fields, risky or misconfigured rollout strategies, RBAC permission changes, and potential ingress or service mesh compatibility issues. 

After the upgrade, Chkk runs postflight checks to verify that the Argo Rollouts controller is functioning properly. It monitors ongoing deployments, ensuring rollouts progress as expected, metric integrations are stable, and no unexpected regressions occur. This thorough, two-phase approach significantly reduces the risk of deployment failures and downtime.

Version Recommendations

Chkk proactively monitors the Argo Rollouts release lifecycle, recommending stable and secure versions best suited for your specific Kubernetes setup. By evaluating known issues, security vulnerabilities, and compatibility concerns, Chkk guides your team away from problematic releases, ensuring you remain on fully supported, reliable versions. This proactive approach helps prevent issues related to outdated software, integration gaps, or unexpected incompatibilities, ensuring continuous stability and security.

Upgrade Templates

Chkk provides structured Upgrade Templates specifically tailored for Argo Rollouts, supporting both in-place rolling updates and blue-green deployments:

  • In-place Rolling Updates: These templates guide you through safely updating Argo Rollouts controllers within your existing cluster environment, ensuring continuous availability through step-by-step pod updates and health checkpoints.
  • Blue-Green Deployments: For critical environments, Chkk supports deploying a parallel Argo Rollouts controller on the new version, allowing full validation and testing before transitioning production workloads. This approach ensures minimal risk and downtime by verifying the stability and performance of the new version prior to the switchover.

Both methods include comprehensive instructions, automated health checks, and built-in rollback plans, significantly reducing manual intervention, preventing human errors, and ensuring reliable upgrades.

Preverification

Chkk's preverification feature simulates complex upgrades within an isolated "digital twin" environment. By applying your actual configurations, including rollout strategies and metric integrations, Chkk detects potential conflicts, misconfigurations, and compatibility issues before reaching production. This advanced validation significantly enhances safety, minimizes risks, and ensures smooth, predictable transitions.

Supported Packages

Chkk seamlessly integrates with all popular deployment methods, including Helm charts, Kustomize overlays, and raw Kubernetes manifests. It ensures recommended updates align perfectly with your existing GitOps or CI/CD workflows, allowing for consistent, smooth upgrades across diverse deployment strategies and multi-cluster environments.

Chkk’s Core Benefits

Chkk Operational Safety Platform simplifies upgrades, reduces risk, and keeps your Kubernetes infrastructure operational. Here’s how that applies to Argo Rollouts upgrades:

  • Speed Up and De-Risk Upgrades: Manually upgrading Argo Rollouts is time-consuming. Chkk accelerates the process and makes it safer by generating a detailed Upgrade Plan for each cluster. This plan spans all components—control plane, node versions, add-ons, and dependencies—and flags required changes, including recommended add-on versions or deprecated APIs. Instead of piecing together requirements from various release notes, teams receive a clear and actionable upgrade path. Chkk’s automation can cut upgrade preparation time by 3-5x, reducing weeks of planning to just days.
  • Eliminate Redundant Effort: Many organizations squander countless hours on repetitive upgrade planning and research. By unifying upgrade workflows across teams, Chkk prevents duplication of effort and ensures that insights and processes don’t need to be reinvented with every release. This consolidation of efforts can save thousands of hours.
  • Delegate, Parallelize, and Standardize Workflows: Chkk makes it easy to break out upgrade tasks among team members, all while maintaining standardized workflows that reduce confusion and boost efficiency. Engineers spend less time context-switching, and institutional knowledge is retained and shared effectively. During staff turnover or organizational changes, having a historical record of upgrade best practices prevents delays.
  • Enhance Operational Safety: Kubernetes upgrades introduce inherent risk, but Chkk helps you detect and fix potential problems before they cause disruptions. With automated risk detection, your team can prevent hundreds of potential breakages annually—for every hundred clusters—saving significant break-fix effort. By focusing on proactive measures, you can innovate rather than constantly firefighting.
