Apisix Ingress

不建议使用
依赖 etcd
- etcd 难维护
- helm 直接启动的 etcd 可能会有各种问题 - 可能导致无法启动
- 没必要为了 apisix 专门去维护 etcd
- etcd 非常吃 IO - IO 慢的时候 CPU 非常高
建议尝试 kong - 使用现有的 DB 作为 backend

IngressController

ApisixRoute
ApisixUpstream
- 名字与 service 名字相同会自动匹配
ApisixTls
ApisixClusterConfig
- 配置 prometheus、skywalking
ApisixConsumer
ApisixPluginConfig
- ingress 通过 annotation 引用 k8s.apisix.apache.org/plugin-config-name: "echo-and-cors-apc"
