cluster-api-provider-kind's Issues

Reconcile logic: create/delete cluster

Implement a reconcile logic able to create/delete KinD clusters from local host using kind binary

This will highlight potential problems when sync with CAPI Cluster resource and its status

Bump api versions to v1beta1

Current clusterctl version is compatible only with v1beta1 providers:

Using configuration File="/Users/manuel.bovo/.cluster-api/clusterctl.yaml"
Fetching providers
Fetching File="core-components.yaml" Provider="cluster-api" Type="CoreProvider" Version="v1.2.4"

Error: current version of clusterctl is only compatible with v1beta1 providers, detected v1alpha1 for provider infrastructure-kind```

Current clusterctl version:

clusterctl version
clusterctl version: &version.Info{Major:"1", Minor:"2", GitVersion:"v1.2.4", GitCommit:"8b5cd363e11b023c2b67a1937a2af680ead9e35c", GitTreeState:"clean", BuildDate:"2022-10-17T13:42:12Z", GoVersion:"go1.18.7", Compiler:"gc", Platform:"darwin/amd64"}

Solution: bump KindCluster api version

Register all CustomResources to Scheme

Use KinD as Lib

Currently we are using exec and the kind binary to create/delete clusters.
This is pretty ugly, inefficient and make us to depend to an pre-installed kind binary on the controller container image.

Using kind library will avoid all of this
