// ClusterctlUpgradeSpec implements a test that verifies clusterctl upgrade of a management cluster.
//
// NOTE: this test is designed to test older versions of Cluster API --> v1beta1 upgrades.
// This spec will create a workload cluster, which will be converted into a new management cluster (henceforth called secondary
// managemnet cluster)
// with the older version of Cluster API and infrastructure provider. It will then create an additional
// workload cluster (henceforth called secondary workload cluster) from the new management cluster using the default cluster template of the old release
// then run clusterctl upgrade to the latest version of Cluster API and ensure correct operation by
// scaling a MachineDeployment.
//
// To use this spec the fields InitWithBinary and InitWithKubernetesVersion must be specified
// in the spec input. See ClusterctlUpgradeSpecInput for further information.
//
// In order to get this to work, infrastructure providers need to implement a mechanism to stage
// the locally compiled OCI image of their infrastructure provider and have it downloaded and available
// on the secondary management cluster. It is recommended that infrastructure providers use `docker save` and output
// the local image to a tar file, upload it to object storage, and then use preKubeadmCommands to pre-load the image
// before Kubernetes starts.
//
// For example, for Cluster API Provider AWS, the docker image is stored in an s3 bucket with a unique name for the
// account-region pair, so as to not clash with any other AWS user / account, with the object key being the sha256sum of the
// image digest.
//
// The following commands are then added to preKubeadmCommands:
//
// preKubeadmCommands:
// - mkdir -p /opt/cluster-api
// - aws s3 cp "s3://${S3_BUCKET}/${E2E_IMAGE_SHA}" /opt/cluster-api/image.tar
// - ctr -n k8s.io images import /opt/cluster-api/image.tar # The image must be imported into the k8s.io namespace
