Maven / ArgoCD interview questions

What is the ArgoCD CLI and what are the most common commands used day-to-day?

The ArgoCD CLI (argocd) is a command-line tool for interacting with the ArgoCD API Server. It is the primary interface for operators who prefer the terminal over the UI and is also used in CI/CD pipelines for triggering or waiting on syncs.

Before using the CLI, you must log in:

argocd login <argocd-server> --username admin --password <password>
# Use --grpc-web if behind an HTTP proxy or load balancer

Common day-to-day commands:

CommandPurpose
argocd app listList all Applications with sync and health status
argocd app get <app>Show detailed status, sync info, and resource tree for an Application
argocd app sync <app>Trigger a sync; add --prune to allow pruning, --dry-run to preview
argocd app wait <app>Block until the Application reaches a target health/sync state (useful in CI)
argocd app diff <app>Show the diff between live cluster state and Git desired state
argocd app rollback <app> <id>Roll back to a specific sync history revision
argocd app set <app> --helm-set key=valOverride Helm values at the Application level without changing Git
argocd cluster listList all registered clusters
argocd proj listList all AppProjects

In CI/CD pipelines, the typical pattern is: build image → push image → update Git tag → argocd app wait <app> --health to block the pipeline until ArgoCD confirms the deployment is healthy.

Which CLI command is most useful in a CI/CD pipeline to block execution until a deployment is healthy?
What does the --dry-run flag do in argocd app sync?
