Gruntwork GitOps "GruntOps"

View Source Release Notes

GitOps is an operational framework that is built around DevOps best practices for a standardized approach to managing the lifecycle of Kubernetes based deployments. GitOps provides a unified approach to the deployment and management of container workloads, with Git being the single source of truth for the state of the container infrastructure. GitOps is a very developer-centric workflow that works best when adopted by individuals and teams that follow a git based development lifecycle. The core principles of GitOps have been at the center of Gruntwork from the beginning!

Getting Started​

To use this module, you will need to have a running EKS cluster prior to deploying this module. See the Argo CD Example for an example of how to deploy this module.

This module deploys the Helm Chart version of Argo CD. All available configurations can be found in the repository of the Argo CD Helm Chart. The default configuration of this module will deploy the Argo CD Helm Chart with it's default values. To configure the Helm Chart to meet the needs of your deployment, configure the argocd_chart_additional_values variable in the variables file.

Connecting to the Argo CD UI​

Argo CD has a UI component for the ability to interact with the Argo CD application. You can connect to the UI in multiple ways:

  1. Connect via a Load Balancer Service
  2. Connect via Ingress
  3. Connect via Port Forwarding

Please see the Argo CD for detailed information on each of the methods for connecting to the UI.
