RKE1 示例 YAML

以下是一个供参考的 RKE 模板配置文件示例。

RKE 模板中的 YAML 使用与创建 RKE 集群时相同的自定义项。但是，由于 YAML 位于 Rancher 配置的 RKE 集群的上下文中，因此 RKE 文档中的自定义项需要嵌套在 rancher_kubernetes_engine 指令下。

#
# Cluster Config
#
docker_root_dir: /var/lib/docker

enable_cluster_alerting: false
# This setting is not enforced. Clusters
# created with this sample template
# would have alerting turned off by default,
# but end users could still turn alerting
# on or off.

enable_cluster_monitoring: true
# This setting is not enforced. Clusters
# created with this sample template
# would have monitoring turned on
# by default, but end users could still
# turn monitoring on or off.

# # 目前仅支持 Nginx ingress provider
# # 要禁用 Ingress controller，设置 `provider: none`
# # 要在指定节点上禁用 Ingress，使用 node_selector，例如：
#    provider: nginx
#    node_selector:
#      app: ingress
#
  ingress:
    provider: nginx
