Continuous delivery in Kubernetes (ArgoCD)

In modern software development, approaches that enable automation, continuous integration, and delivery (CI/CD) of applications are gaining increasing popularity. One such approach is GitOps, which allows managing infrastructure and applications through a version control system such as Git. In the context of Kubernetes, automating the delivery process is key to maintaining stability, reliability, and fast deployment of changes.

ArgoCD is a popular tool for implementing Continuous Delivery (CD) in Kubernetes based on GitOps principles. It is installed as an additional service in the Kubernetes cluster and automatically synchronizes the cluster’s state with configurations (deployments, services, configmaps, etc.) stored in a Git repository. With ArgoCD, you can easily set up automatic cluster deployment and maintain a single Source of Truth.

Some of the benefits of ArgoCD:

• ArgoCD constantly monitors the Kubernetes state and synchronizes it with changes in the Git repository, either automatically or manually, ensuring the infrastructure stays up-to-date.
• It allows managing multiple Kubernetes clusters seamlessly.
• ArgoCD integrates smoothly with the Helm package manager.
• It provides the ability to quickly revert to previous versions of the application.
• ArgoCD does not require additional configuration access to the cluster’s configuration and allows easy implementation of role-based access control for teams.
• It features a convenient web-based interface.

ArgoCD is an excellent choice for those looking for an efficient tool to automate application deployment in Kubernetes. It covers most tasks related to Kubernetes cluster deployment while potentially requiring additional configuration for more complex use cases and integrations.
