ArgoCD is a declarative, GitOps continuous delivery tool for Kubernetes clusters that extends the benefits of declarative specifications and Git-based configuration management. It can also be deployed on multiple clusters and is enterprise friendly

Terminologies

• Application: group of Kubernetes resources as defined by a manifest
  • Has source (Github repo, also helm charts, etc..) and a destination (server namespace)
• Application source type: tool used to build the application (Helm, Kustomize, etc..)
• Project: logical grouping of applications (used to define access control)
• Target state: desired state of an application as represented in the repository
• Live state: what pods, configmaps, secrets, etc.. are created in the cluster
• Sync status: whether or not the live state matches the target state
• Refresh: compare latest code in Git with the live state
