Argo Rollouts

Argo Rollouts

Argo Rollouts is an advanced deployment solution that extends ArgoCD, one of the most popular declarative, GitOps continuous delivery tools for Kubernetes. It facilitates progressive delivery, allowing developers to deploy new features and updates progressively with fine-grained control, reducing the risk of introducing new software versions in production.

Key Features of Argo Rollouts

1. Advanced Deployment Strategies

Argo Rollouts supports several advanced deployment strategies, including Blue-Green, Canary, and Experiment. These strategies enable developers to test new versions with a subset of users before a full rollout, ensuring that any issues are detected and addressed early in the deployment process.

2. Automated Rollbacks

One of the standout features of Argo Rollouts is its ability to perform automated rollbacks. If a new version encounters issues or doesn’t meet the specified criteria, the system can automatically revert to the previous, stable version, minimizing downtime and user impact.

3. Metrics Analysis

Argo Rollouts integrates with Prometheus for metrics analysis, allowing developers to define key performance indicators (KPIs) for their applications. By analyzing these metrics, developers can make informed decisions about whether to proceed with a deployment or rollback.

4. Web UI

Argo Rollouts provides a comprehensive Web UI that offers a visual representation of the deployment process. It allows developers to monitor the progress of rollouts, view the status of replicasets, and access logs, making it easier to manage deployments.

5. Fine-Grained Traffic Routing

With its support for service mesh technologies like Istio, Argo Rollouts can control traffic routing between different versions of an application with precision. This is crucial for implementing Canary releases where only a small percentage of users are directed to the new version initially.

6. Experimentation

Argo Rollouts supports experimentation, allowing developers to run A/B testing to compare different versions of an application. This feature is invaluable for testing new features and enhancements with real users and gathering feedback before a widespread rollout.

7. Scalability

Argo Rollouts is designed to scale with the needs of the organization. Whether deploying to a small cluster or managing multiple large-scale deployments across different environments, Argo Rollouts ensures consistent and reliable delivery.

8. Integration with ArgoCD

Being an extension of ArgoCD, Argo Rollouts leverages ArgoCD’s strengths, such as declarative configuration, GitOps workflow, and multi-cluster management, providing a seamless and integrated experience for continuous delivery.


Argo Rollouts is a powerful tool for organizations looking to implement progressive delivery in their continuous delivery pipelines. Its advanced deployment strategies, automated rollbacks, and integration with metrics and service mesh technologies make it a versatile choice for managing Kubernetes deployments. By leveraging ArgoCD Rollouts, development teams can ensure that new application versions are introduced to production environments in a controlled, scalable, and reliable manner, optimizing the user experience and minimizing risks.
