Ingress 端口转发

一、Ingress controller添加参数

配置文件 ingress-controller

?

1 2 3 4

# kubectl edit daemonset ingress-nginx-controller -n ingress-nginx ​ - --tcp-services-configmap=$(POD_NAMESPACE)/tcp-services - --udp-services-configmap=$(POD_NAMESPACE)/udp-services

　　

二、新增configmap

?

1 2 3 4 5 6 7

apiVersion: v1 kind: ConfigMap metadata:   name: tcp-services   namespace: ingress-nginx data:   6379: "default/redis-cluster-connection:6379"

• 6379: "default/redis-cluster-connection:6379" ： 将default NameSpace下redis-cluster-connection这个Service的端口6379通过ingress节点的6379端口转发

三、查看ingress转发配置

?

1 2 3 4 5 6 7 8 9 10 11

# TCP services           server {         preread_by_lua_block {             ngx.var.proxy_upstream_name="tcp-default-redis-cluster-connection-6379";         }                   listen                  6379;                   listen                  [::]:6379; ​
