一、Ingress
service模式：
loadbalance
NodePort：每个节点都会有一个指定的端口 30000-32767 内网
clusterip：默认模式，只能pod内部访问
externalName：需要dns提供域名
1.1、对外提供服务的ingress
service：网关的概念-----标签来匹配pod，还能通过endpoint更新pod的变化，集群内部的ip地址。也可以实现负载均衡，四层代理。
service暴露的端口只能用于内网访问，局域网。
loadbalance-------公有云--------提供负载均衡的ip-------公网地址。
Ingress
Ingress：在k8s当中，Ingress是一个独立的组件（deployment ns svc）独立的配置，只能通过yaml文件配置。不能命令行。
定义请求如何转发到service的规则。
ingress通过http或者https暴露内部的service，给service提供外部的url，负载均衡 SSL/TLS。基于域名的反向代理。
ingess通过ingress-controller来实现上述的功能。
ingress-controller不是k8s自带的组件，这是插件的统称。
k8s维护的插件类型
- glogle云的GCE
- Ingress-nginx-------最常用的模式
- traefik--------------带可视化界面—ui界面—并发量只有ingress-nginx的流程。
流量转发示意图:
1.2、ingress-nginx暴露服务的方式：
- 1、deployment+loadbalance------->service
- 需要公有云提供负载均衡的ip地址---------公网地址。
- 2、DaemonSet+HostNetwork + NodeSelector
- ingress-controller会在每个节点部署一个pod，ingress-controller直接使用每个节点的80和443端口，直接实现流量的转发和访问。
NodeSelector用来选择设备优良，或者选择端口没被占用的节点。
DaemonSet+HostNetwork + NodeSelector模式：
- 优点:
使用宿主机端口，适合大并发的生产环境，性能是最好的 - 缺点:
- 和宿主机公用端口，一个node节点只能部署一个ingress-controller的pod
3、Deployment+nodePort模式：
nodePort--------->30000-------80—80
ingress根据副本数和调度在节点上部署多个pod。在根据nodePort在每个节点打开一个指定的端口 30000-32767
客户端--------->www.xy102.com------------->service-------------->nodeport---------->clusterip-------容器端口
1、这种模式优点：不占用宿主机的端口，配置简单使用于内部并发不大的访问。
2、缺点，性能差，多了一个nodeport还涉及nodeport的转发，实际上通过nat模式做地址转换，性能上有影响。
3、DaemonSet+HostNetwork + NodeSelector模式

8181 端口是nginx-controller的默认配置，当ingress没有资源可以匹配时，会自动转发到这个端口。

##解释
openssl req -x509 -sha256 -nodes -days 365 -newkey rsa:2048 -keyout tls.key -out tls.crt -subj "/CN=CHINA/O=NJ"
req：表示指定证书请求和生成相关文件
-x509：生成自签名的x.509证书
-sha256：sha-256的散列算法
-nodes：生成的私钥不加密
-days 365: 证书的有效期为365天
-newkey rsa:2048：:表示使用RSA的密钥队，长度2048个单位
-keyout tls.key -out tls.cr：生成两个文件
-keyout 私钥保存到tls.key文件
-out 保存证书到tls.crt
-subj 添加证书的主题
