+• instructions on how to use the ProviderJet template to create a new repository
+• Specifying provider name lower and upper case in a command
+• Replacing all instances of template with the specified commands
+• Understanding Terraform provider source and download name in Docker files
+• Clarifying that Terraform provider source and download name are not the same thing
+• Identifying the correct URL for the Linode Terraform provider
+• Finding the changelog for the Terraform provider Linode
+• Examining GitHub as a potential example of the V4 version
+• Discussion about determining if a Linode provider is using an old version
+• Importance of checking the Git repo for the Terraform provider to confirm version
+• Realization that the V4 version is available as a Go package and can be imported
+• Identifying the line in the Go module that needs to be updated or replaced
+• Understanding how to use replace statements in the Go module to update dependencies

+• TerraJet, a tool for utilizing the Terraform community's work in Crossplane
+• Creating a Linode provider using TerraJet and Terraform
+• TerraJet's design and functionality as a code generator and controller
+• The history of Marcus's involvement with Terraform and Linode
+• The current state of providers generated with TerraJet, including AWS, Azure, GCP, and others.
+• ProviderJet AWS has 765 custom resource definitions (CRDs), which is too many for the Kubernetes community
+• Another provider was added in the last week, which generated a ProviderJet Linode with 12 commits to Crossplane Contrib
+• The previous Linode provider in Crossplane had not been maintained and may not work with the latest versions of Crossplane
+• A single resource (LKE cluster) is currently available for provisioning in TerraJet, but additional resources are needed
+• Future plans include announcements about stabilized providers (AWS, Azure, GCP), versioned resources, and conversion webhooks
+• Implementing a cross-plane provider using TerraJet
+• Ease of use with TerraJet compared to other implementations
+• Example of a community-written provider (Exoscale) in 6 hours
+• Adding an instance resource to JetLinit provider as simple as 10-15 lines of code
+• Step-by-step process for creating a Crossplane Linode provider
+• Installing Crossplane and the Linode provider using Helm
+• Discussion of crossplane RBAC manager and pods
+• Using Canines as a CLI for quick tasks
+• Creating new clusters with Linode jet crossplane IO V1 alpha 1 group
+• Provisioning new clusters using crossplane LKE
+• Overview of how crossplane continuously reconciles requests
+• Creation of a new LKE instance and cluster in Linode and Kubernetes
+• Obtaining kubeconfig for the newly created cluster
+• Discussion of using Crossplane to target a Kubernetes cluster without exposing the kubeconfig
+• Exploring self-automated system where Crossplane provisions resources and updates application
+• Demonstration of deleting a cluster and observing the controller's behavior in reconciling the absence of the cluster
+• Explanation of how the controller will try to create a new cluster if it detects that one is missing, with a wait period of up to 1 minute
+• Discussion of a custom resource that triggers a Kubernetes event
+• Cluster creation and reconciliation process
+• Issue with Linode node pool being deleted when cluster was deleted from UI
+• Introduction to composite resources and their benefits in managing multiple resources as one
+• Explanation of how composite clusters can recreate nodes, installations, and other dependencies automatically
+• Example scenario where accidental deletion of a cross-plane cluster led to discussion on the importance of automated recreation of dependent resources
+• Idea of improving current functionality by installing base components and using two compositions with XRDs to define APIs for multiple resources.
+• Clusterscoped does not have any namespaces
+• Creating a composition with base system components for a cluster
+• Using a central production cluster with its own claim, similar to PVC, and referencing it from other namespaces via XRD
+• Publishing a new API instead of manually configuring cloud-specific fields
+• Moving Crossplane from being hosted on the current cluster to a seed cluster on a cloud like AWS or GCP
