Summary

📄🛠️🚀

This pull request adds the initial scaffolding and implementation of a license controller, which is a Kubernetes controller that manages License custom resources. The pull request uses kubebuilder, controller-gen, and kustomize tools to generate the project structure, code, and configuration files. The pull request also adds a Dockerfile, a Makefile, and a launcher program to build and run the controller image. The pull request defines the License type and its spec and status fields, and implements the main logic for the controller manager. The pull request also adds some .gitignore and .dockerignore files to ignore irrelevant files. The pull request is a work in progress and needs more documentation and testing.

autumn of code starts

Walkthrough

• Add a license controller project with scaffolding and basic files (link-link)
• Create a .dockerignore and .gitignore file to exclude irrelevant files from the image and the repository (link, link)
• Define a Dockerfile to build the image for the license controller, using a launcher as the entry point (link)
• Define a Makefile to automate the common tasks for building, testing, generating, and deploying the license controller (link)
• Create a PROJECT file to track the information used to scaffold the project and allow the plugins to work properly (link)
• Create a README.md file to provide a brief overview of the project and its purpose, as well as some instructions on how to get started, contribute, and license the project (link)
• Define the License type and its spec and status fields, as well as the LicenseList type, with some validation and defaulting annotations, and some constants for the license type and status phase (link)
• Register the license API group and version with the scheme, and provide a SchemeBuilder and AddToScheme function for adding the types in this group-version to the given scheme (link)
• Implement the DeepCopy, DeepCopyInto, and DeepCopyObject methods for the License and LicenseList types, which are required for the types to implement the runtime.Object interface and to be used by the controller (link)
• Define the CustomResourceDefinition for the License type, specifying the group, version, kind, scope, schema, subresources, and validation of the License type (link)
• List the resources and patches for the CRDs, including some commented out patches for enabling webhook and cert-manager for the CRD, and a configurations section that teaches kustomize how to substitute name and namespace references in the CRD (link)
• Define the nameReference, namespace, and varReference for the CRD, telling kustomize how to update the service name and namespace in the webhook clientConfig, and how to add the cert-manager annotation to the CRD metadata (link)
• Add a directive for cert-manager to inject CA into the CRD, specifying the cert-manager.io/inject-ca-from annotation with the certificate namespace and name as the value (link)
• Enable a conversion webhook for the CRD, specifying the conversion strategy, webhook clientConfig, and conversionReviewVersions for the CRD (link)
• List the resources and patches for the default configuration of the license controller, including the crd, rbac, manager, and optionally webhook, certmanager, and prometheus subdirectories as resources, and some patches for adding auth proxy, webhook, and cert-manager to the manager deployment, and setting the namespace and namePrefix for all resources, and some replacements for adding cert-manager annotations to the webhook service and configurations (link)
• Inject a sidecar container that is a HTTP proxy for the controller manager, performing RBAC authorization against the Kubernetes API using SubjectAccessReviews, and protecting the /metrics endpoint by putting it behind auth (link)
• Add a placeholder for adding additional arguments or environment variables to the manager container (link)
• Define the main program for the license controller, setting up the logger, manager, database, and controller, and adding health and readiness checks, and parsing some flags for metrics, probes, and leader election, and using the current kubeconfig context to connect to the cluster (link)
• Define a simple launcher program that runs the preset and manager binaries in parallel using exec.Command and sync.WaitGroup, and use it as the entry point for the Docker image (link)
• Define a stub for the preset program that will be run by the launcher, and is intended to perform some initialization or configuration tasks before the manager starts, such as creating or updating CRDs, RBAC, or webhooks (link)
