Frequently Asked Questions — Argo CD
What problem does Argo CD solve?
Argo CD automates a specific part of the software delivery lifecycle — container orchestration, CI/CD, configuration management, or observability. It reduces manual toil, enforces consistency across environments, and speeds up the feedback loop from code to production.
How do you handle secrets and credentials in Argo CD?
Never store secrets in configuration files or version control. Use a dedicated secrets manager (HashiCorp Vault, AWS Secrets Manager, or the platform's built-in store), inject environment variables at runtime, and rotate secrets regularly.
How does Argo CD integrate with Kubernetes?
Argo CD typically integrates with Kubernetes via manifests, Helm charts, or a native operator. CI pipelines build images and push to a registry; CD pipelines update manifests and trigger Kubernetes rollouts. Many tools have native Kubernetes support or plugins.
What does good observability look like with Argo CD?
The three pillars of observability are metrics (what is happening), logs (why it happened), and traces (where time is spent). Configure Argo CD to emit structured logs, expose Prometheus metrics, and integrate with a tracing backend. Set alerts on error rates and latency SLOs.
How do you get started with Argo CD in a new project?
Start with the quickstart guide, set up a minimal working pipeline or configuration, and validate it end-to-end before adding complexity. Most tools have local development modes — use them to iterate without affecting production. Add monitoring from day one.
Who Is This For?
DevOps engineers, SREs, and platform engineers who use Argo CD to manage deployments, container orchestration, or infrastructure automation.
