The GitOps workflow using Argo CD enables the deployment and synchronization of a Consul cluster on Kubernetes, ensuring that version control remains the primary source of truth for Consul cluster and service mesh configuration. This approach allows for consistent deployment of configuration across different Consul clusters, clouds, and environments, standardizing management of Consul across multiple Kubernetes clusters. Automation with Argo CD hooks and sync waves facilitates synchronization of Consul resources on Kubernetes, coordination of changes to different resources, and upgrade of Consul servers and components. By using a GitOps tool like Argo CD, developers can centralize the automation, installation, and configuration of services onto multiple Kubernetes clusters, reducing manual effort and increasing consistency across environments.
