The Argo Rollouts tool provides a progressive delivery solution for managing rollouts and rollbacks in Kubernetes environments. It offers two deployment strategies: canary releases and blue-green deployments. Canary releases allow for gradual rollout of updates to a subset of users, while blue-green deployments involve creating an identical environment for the new version, allowing for instant rollback if needed. Argo Rollouts simplifies these processes by providing a user-friendly interface and command-line tools. The tool's features include auto-promotion, pause, setWeight, and abort commands, which enable fine-grained control over the rollout process. By using Argo Rollouts, developers can ensure reliable and efficient updates to their applications, minimizing downtime and improving user experience.
