红帽全球峰会1.5. MicroShift 网络组件和服务
本简要概述在 MicroShift 中描述了网络组件及其操作。microshift-networking RPM 是一个软件包，可自动拉取任何与网络相关的依赖项和 systemd 服务来初始化网络，例如 microshift-ovs-init systemd 服务。
- NetworkManager
-
NetworkManager 需要在 MicroShift 节点上设置初始网关网桥。NetworkManager 和
NetworkManager-ovsRPM 软件包作为依赖项安装到microshift-networkingRPM 软件包，该软件包包含必要的配置文件。MicroShift 中的 NetworkManager 使用keyfile插件，并在安装microshift-networkingRPM 软件包后重新启动。 - microshift-ovs-init
-
microshift-ovs-init.service由microshift-networkingRPM 软件包安装，作为依赖的 systemd 服务到microshift.service。它负责设置 OVS 网关网桥。 - OVN 容器
两个 OVN-Kubernetes 守护进程集由 MicroShift 渲染和应用。
-
ovnkube-master 包含
northd,nbdb,sbdb和ovnkube-master容器。 ovnkube-node ovnkube-node 包含 OVN-Controller 容器。
MicroShift 启动后，OVN-Kubernetes 守护进程集会在
openshift-ovn-kubernetes命名空间中部署。
-
ovnkube-master 包含
- 打包
OVN-Kubernetes 清单和启动逻辑内置在 MicroShift 中。
microshift-networkingRPM 中包含的 systemd 服务和配置有：-
/etc/NetworkManager/conf.d/microshift-nm.confforNetworkManager.service -
/etc/systemd/system/ovs-vswitchd.service.d/microshift-cpuaffinity.conf用于ovs-vswitchd.service -
/etc/systemd/system/ovsdb-server.service.d/microshift-cpuaffinity.conf用于ovs-server.service -
/usr/bin/configure-ovs-microshift.shformicroshift-ovs-init.service -
/usr/bin/configure-ovs.shformicroshift-ovs-init.service -
/etc/crio/crio.conf.d/microshift-ovn.conf用于 CRI-O 服务
