红帽全球峰会第 3 章 OpenShift Virtualization 架构
了解 OpenShift Virtualization 架构。
3.1. OpenShift Virtualization 架构如何工作
安装 OpenShift Virtualization 后，Operator Lifecycle Manager(OLM)会为 OpenShift Virtualization 的每个组件部署 operator pod：
-
Compute:
virt-operator -
Storage:
cdi-operator -
Network:
cluster-network-addons-operator -
Scaling:
ssp-operator -
Templating:
tekton-tasks-operator
OLM 还会部署 hyperconverged-cluster-operator pod，它负责其他组件的部署、配置和生命周期，以及几个 helper pod: hco-webhook 和 hyperconverged-cluster-cli-download。
成功部署所有 Operator pod 后，您应该创建 HyperConverged 自定义资源 (CR)。HyperConverged CR 中的配置充当 OpenShift Virtualization 的单一的信任源和进入点，并指导 CR 的行为。
HyperConverged CR 为其协调范围中的所有其他组件的 operator 创建对应的 CR。然后，每个 Operator 会为 OpenShift Virtualization control plane 创建资源，如守护进程集、配置映射和其他组件。例如，当 hco-operator 创建 KubeVirt CR 时，virt-operator 会协调它并创建其他资源，如 virt-controller、virt-handler 和 virt-api。
OLM 部署 hostpath-provisioner-operator，但在创建 hostpath provisioner (HPP)CR 之前，它无法正常工作。
