Definition

Argo Image Updater is an open-source tool designed to automate the process of updating container images in Kubernetes clusters managed by Argo CD. It monitors container image registries for new image versions and updates the Kubernetes manifests accordingly, ensuring that applications are always running the latest versions of their container images. This tool helps streamline the continuous delivery process by integrating seamlessly with Argo CD to manage application deployments.
