Container Rollback

Roll back a container image for Kubernetes or Docker Services

Container Rollback in DuploCloud allows users to quickly revert a Kubernetes or Docker Service's container image to a previous, stable version. This is especially useful in scenarios where a newly deployed container image introduces issues, errors, or failures in the application. With this feature, users can ensure minimal downtime and maintain the stability of their Services by rolling back to a known good state. Container rollback is support for:

• Kubernetes (on EKS, AKS, GKE, and DuploCloud Kubernetes)

• Docker Services (on ECS)
