Spacelift has introduced Kubernetes integration, allowing users to provision a Kubernetes cluster on AWS using Terraform with Spacelift. The blog provides a step-by-step guide for deploying an EKS cluster, starting with cloning a Terraform repository on GitHub and configuring it within Spacelift. Users create a Stack in Spacelift, integrate with their VCS, configure backend settings, and set up necessary AWS integrations. The deployment process involves triggering a run, which initiates a Terraform Plan and ultimately deploys the EKS cluster, with outputs accessible for review. Spacelift simplifies Terraform management by offering features like policy as code, context sharing, drift detection, and resource visualization, and encourages users to start with a free trial to explore its capabilities.
