+# rancher-monitoring-crd
+A Rancher chart that installs the CRDs used by rancher-monitoring.
+
+## How does this chart work?
+
+This chart marshalls all of the CRD files placed in the `crd-manifest` directory into a ConfigMap that is installed onto a cluster alongside relevant RBAC (ServiceAccount, ClusterRoleBinding, ClusterRole, and PodSecurityPolicy).
+
+Once the relevant dependent resourcees are installed / upgraded / rolled back, this chart executes a post-install / post-upgrade / post-rollback Job that:
+- Patches any existing versions of the CRDs contained within the `crd-manifest` on the cluster to set `spec.preserveUnknownFields=false`; this step is required since, based on [Kubernetes docs](https://kubernetes.io/docs/tasks/extend-kubernetes/custom-resources/custom-resource-definitions/#field-pruning) and a [known workaround](https://github.com/kubernetes-sigs/controller-tools/issues/476#issuecomment-691519936), such CRDs cannot be upgraded normally from `apiextensions.k8s.io/v1beta1` to `apiextensions.k8s.io/v1`.
+- Runs a `kubectl apply` on the CRDs that are contained within the crd-manifest ConfigMap to upgrade CRDs in the cluster
+
+On an uninstall, this chart executes a separate post-delete Job that:
+- Patches any existing versions of the CRDs contained within `crd-manifest` on the cluster to set `metadata.finalizers=[]`
+- Runs a `kubectl delete` on the CRDs that are contained within the crd-manifest ConfigMap to clean up the CRDs from the cluster
+
+Note: If the relevant CRDs already existed in the cluster at the time of install, this chart will absorb ownership of the lifecycle of those CRDs; therefore, on a `helm uninstall`, those CRDs will also be removed from the cluster alongside this chart.
+
+## Why can't we just place the CRDs in the templates/ directory of the main chart?
+
+In Helm today, you cannot declare a CRD and declare a resource of that CRD's kind in templates/ without encountering a failure on render.
+
+## [Helm 3] Why can't we just place the CRDs in the crds/ directory of the main chart?
+
+The Helm 3 `crds/` directory only supports the installation of CRDs, but does not support the upgrade and removal of CRDs, unlike what this chart facilitiates.
