ArgoCD (EN)

Popis kurzu

ArgoCD is a kubernetes controller that continuously monitors running applications and compares the current, live state with the desired target state.

Today, ArgoCD is one of the world's most popular open-source GitOps tools, which automates the deployment of applications in Kubernetes or OpenShift environments.



GitOps is a natural extension of Infrastructure-as-Code and Continuous Delivery principles with a focus on using Git as the single source of truth. Changes to infrastructure and applications are made declaratively through versioned changes in Git, an automated process that ensures the actual state of your system is an image of the declared state stored in Git.
