Practical GitOps CI/CD with Jenkins and ArgoCD

Hello, I’m Lee Do-won.

"I’ve built a Jenkins pipeline, but I’ve only heard of ArgoCD and GitOps as concepts."

"I’m at a loss as to how to design deployments for each environment: dev, staging, and production."

For those of you facing these challenges, we’ve launched the “Practical GitOps CI/CD with Jenkins and ArgoCD” course on Inflearn.

Here’s what sets this course apart

• Beyond traditional Jenkins-based CI/CD, we also cover ArgoCD-based GitOps.

• We directly compare the Push approach (Jenkins) and Pull approach (ArgoCD) on the same cluster. You can see firsthand that when someone makes a manual change with kubectl, one remains as is while the other is automatically restored, and directly experience the differences in how rollbacks and deployment histories are checked.

• Combine the two approaches to build a hybrid deployment pipeline from start to finish, with Jenkins Push for dev and staging, and ArgoCD Pull for production (manual Sync approval).

• Practice essential deployment techniques required for operations, including Canary, Blue-Green, RBAC, approval procedures, incident response, and automatic rollbacks.

Practice environment

We’ll use Docker Desktop only. It works on both Windows and macOS, and you don’t need a cloud account like AWS or any additional expenses.

Recommended for

• Backend and infrastructure engineers who have used Jenkins but are new to ArgoCD/GitOps

• Those who want to move from manual kubectl apply to automated Kubernetes deployments

• DevOps and SRE professionals concerned with operational requirements such as deployment approvals, rollbacks, and audit trails

The total runtime is approximately 10–11 hours, and hands-on materials and a troubleshooting guide are also provided.
