Infrastructure-as-Code (IaC) tools like Chef, Puppet, and Terraform led to automating server configuration and managing infrastructure through code.Terraform, with its Terraform language, managed existing machine states but lacked a central registry, leading to its limitation.Pulumi, an alternative, allows describing infrastructure in existing programming languages, offering more flexibility.The Cloud's evolution highlighted the need for tools like Kubernetes for automated drift correction, paving the way for Crossplane.Crossplane leverages Kubernetes to manage various resources like cloud services, GitHub projects, and software stacks.Crossplane's extensibility through packages allows defining higher-level abstractions and integrating with third-party systems.The installation process for Crossplane involves setting up providers like GCP, creating necessary secrets, and managing resources.Google Cloud Platform (GCP) integration with Crossplane involves creating Provider objects, credentials, and configurations.Creating GKE clusters using Crossplane involves specifying cluster configurations, writing connection secrets, and monitoring cluster creation.The ability to manage GKE clusters and resources efficiently through Crossplane showcases its potential for automating infrastructure tasks.
