Infrastructure as Code (IaC) is the management and provisioning of infrastructure through code rather than manual processes. Over time, IaC has evolved with languages being either imperative or declarative. The Kubernetes ecosystem has become a significant part of infrastructure-related developments. Spacelift uses Kubernetes for its infrastructure and supports customers' deployment of private workers on Kubernetes via Helm. Kustomize drives Kubernetes support in Spacelift, allowing users to run kubectl from a task within a stack. The platform aims to provide an alternative to homegrown solutions on top of generic CI, helping overcome common state management issues and adding essential capabilities for infrastructure management.
