一覽

Argo CD is a declarative, GitOps-based continuous delivery tool for Kubernetes. You define desired state in Git (YAML files), and Argo CD continuously reconciles the cluster to match. Advanced practitioners design multi-environment deployments, implement sophisticated sync strategies, secure secrets, and integrate with CI systems. Argo CD is the de-facto standard for Kubernetes CD (alongside Flux). Demand is high. Senior Argo CD engineers earn $130k-190k.

什麼是 Argo CD Advanced Deployment

Argo CD is a GitOps continuous delivery tool. Instead of imperative deployments (kubectl apply), you declare desired state in Git and Argo CD continuously reconciles reality to match the declaration. Advanced practitioners use Argo CD to orchestrate complex deployments: multi-environment (dev, staging, prod), canary rollouts, secrets management, multi-cluster deployments, and integration with CI systems.

❓ 常見問題

How does Argo CD differ from Flux?
Both are GitOps. Argo CD: pull-based (asks Git for state), more UI features, simpler for beginners. Flux: push-based (reacts to Git changes), more extensible. For simplicity: Argo CD. For complex multi-repo: Flux.
What's the typical Argo CD workflow?
Developer commits code → CI builds image, updates YAML → Git repo changes → Argo CD detects change → reconciles Kubernetes → app deploys. All in Git.
How do I manage secrets in Argo CD?
Use sealed-secrets (encrypts secrets in Git) or external secret operator (fetches from vault at deploy time). Never commit plain secrets.
Can I deploy across multiple clusters?
Yes. Argo CD connects to multiple clusters, reads from single Git repo, deploys to each cluster. Multi-cluster CD patterns: canary, blue-green, progressive.
What's the typical sync frequency?
Argo CD continuously watches Git (default 3-minute check) and cluster state (real-time via API watch). Drift is detected in seconds.
How do I do blue-green or canary with Argo CD?
Argo Rollouts (companion project) provides progressive delivery. Canary: gradually shift traffic to new version, auto-rollback if metrics fail.
Is Argo CD production-ready?
Yes. 1000s of companies run it at scale. HA setup recommended: multiple API servers, Redis backend. Otherwise single-server is sufficient for small teams.
