k8s services和ingress区别

K8S中的Services和Ingress是两个不同的概念：

Services：用于在集群内部对Pod进行负载均衡和服务发现。通过Services，可以将多个Pod视为单个资源，从而简化管理和访问。

Ingress：用于在集群外部对服务进行负载均衡和路由。Ingress可以将外部流量路由到集群内部的Services上。Ingress的配置文件可以指定域名和URL路径，从而实现对不同服务的精细控制。

k8s ingress 配置socket

Kubernetes Ingress 可以支持 WebSocket 协议，但是需要在 Ingress Controller 的配置中启用 WebSocket。以下是一个简单的 WebSocket Ingress 配置示例：

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: my-websocket-ingress
spec:
  rules:
  - host: example.com
    http:
      paths:
      - path: /websocket
        pathType: Prefix
        backend:
          serviceName: my-websocket-service
          servicePort: 80
  ingressClassName: nginx
  annotations:
    nginx.org/websocket-services: my-websocket-service

上述配置中，`nginx.org/websocket-services` 注解告诉 Ingress Controller 启用 WebSocket。在这个示例中，WebSocket 流量将被路由到名为 `my-websocket-service` 的后端服务。

注意，在使用 Ingress 配置 WebSocket 时，需要确保后端服务也支持 WebSocket。

k8s ingress yaml 字段解释

Kubernetes(In short k8s) Ingress is an API object that provides a collection of routing rules that govern how external users access services running in a Kubernetes cluster. In simple terms, Ingress exposes HTTP and HTTPS routes from outside the cluster to services within the cluster.

For creating an Ingress object, a YAML file is used with different fields defined in it. The YAML fields and their explanations are as follows:

1. apiVersion: This field defines the version of the APIs that the YAML is written for.

2. kind: This field defines the type of object being created. In this case, it will be Ingress.

3. metadata: This field consists of data like the name, namespace, labels, and annotations describing the Ingress object.

4. spec: The spec field defines the rules for the Ingress object. The spec consists of different fields like rule, path, backend, and etc which defines routing rules, paths, and backend services of the Ingress object.

I hope this clarifies your doubts regarding the k8s ingress yaml field explanation.
