* Due to `ThirdPartyResources` becoming fully deprecated in Kubernetes v1.8 (replaced by `CustomResourceDefinitions`), existing Canal users upgrading their Clusters to Kubernetes v1.8 must follow the below TPR->CRD migration steps:
1. Run: `kubectl apply -f https://raw.githubusercontent.com/projectcalico/calico/v2.6.2/upgrade/v2.5/manifests/upgrade-job.yaml`
2. Retrieve the pod name from describing the job: `kubectl describe job/calico-upgrade-v2.5`
3. Validate the last log line from the pod reports that it completed successfully: `kubectl logs calico-upgrade-v2.5-<random-id>`
4. Update the `KubernetesVersion` within your ClusterSpec to v1.8 (or above), performing an update & rolling-update to all nodes (will involve downtime)
5. Confirm cluster is back up and all canal pods are running successfully: `kops validate cluster` (this may take a few minutes for the cluster to fully validate)
6. Delete the upgrade job as it is no longer required: `kubectl delete job calico-upgrade-v2.5` (you can also safely delete the `clusterrole`, `clusterrolebinding` and `serviceaccount` resources that were created by the above manifest file)
