5 - 系统镜像

从v0.1.6之前，当RKE部署Kubernetes时，会提取几个镜像，这些镜像用作Kubernetes系统组件。从v0.1.6开始，几个系统镜像的功能合并到一个rancher/rke-tools镜像中，以简化和加快部署过程。

您可以分别配置network plug-ins, ingress controller和dns provider以及这些插件的设置选项。这是用于通过RKE部署Kubernetes的完整系统镜像列表的示例，镜像版本依赖于所使用的Kubernetes image/version

Note: 随着RKE版本的发布，这些镜像上的标签将不再是最新的。此列表是特定v1.10.3-rancher2版本。

  1. system_images:

在v0.1.6之前，我们使用以下镜像代替rancher/rke-tools镜像：

  1. system_images:
  2.     alpine: alpine:latest
  3.     nginx_proxy: rancher/rke-nginx-proxy:v0.1.1
  4.     cert_downloader: rancher/rke-cert-deployer:v0.1.1
  5.     kubernetes_services_sidecar: rancher/rke-service-sidekick:v0.1.0
