這篇文章主要為大家介紹了nginx ingress controller的部署配置,有需要的朋友可以借鑒參考下,希望能夠有所幫助,祝大家多多進(jìn)步,早日升職加薪

引言

開源 Nginx Ingress Controller(k8s 官網(wǎng)推薦)、Nginx Incorporaton (nginx inc，nginx官網(wǎng)) 和 Nginx Incorporaton Plus
當(dāng)多個ingress對象資源配置同一個主機(jī)時，就會發(fā)生主機(jī)沖突。 Ingress Controller 支持兩種處理主機(jī)沖突的選項(xiàng):

Choosing the Winner

If multiple resources contend for the same host, the Ingress Controller will pick the winner based on the creationTimestamp of the resources: the oldest resource will win. In case there are more than one oldest resources (their creationTimestamp is the same), the Ingress Controller will choose the resource with the lexicographically smallest uid.

Merging Configuration for the Same Host

It is possible to merge configuration for multiple Ingress resources for the same host. One common use case for this approach is distributing resources across multiple namespaces.

所以最好一個域名，對應(yīng)一個ingress對象

# describe ingress 報(bào)錯
  Warning  Rejected  17m (x2 over 6d23h)  nginx-ingress-controller  All hosts are taken by other resources
  Warning  Rejected  17m (x2 over 3d17h)  nginx-ingress-controller  All hosts are taken by other resources

一. 部署

wget https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.2.1/deploy/static/provider/cloud/deploy.yaml
# 選擇版本
https://github.com/kubernetes/ingress-nginx/blob/controller-v1.4.0/deploy/static/provider/cloud/deploy.yaml
# 修改yaml中的image,改為自己的
    # 可用國內(nèi)源： registry.cn-hangzhou.aliyuncs.com/google_containers/nginx-ingress-controller:v1.2.1
registry.cn-hangzhou.aliyuncs.com/google_containers/nginx-ingress-controller:v1.8.1
registry.cn-hangzhou.aliyuncs.com/google_containers/kube-webhook-certgen:v20230407

二. 配置

1. 跨域

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: front-web
  namespace: web
  annotations:
    kubernetes.io/ingress.class: "nginx"
    nginx.ingress.kubernetes.io/enable-cors: "true"
    nginx.ingress.kubernetes.io/cors-allow-methods: "PUT, GET, POST, OPTIONS"
    nginx.ingress.kubernetes.io/cors-allow-headers: "Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control"
    nginx.ingress.kubernetes.io/cors-expose-headers: "*, X-CustomResponseHeader"
    nginx.ingress.kubernetes.io/cors-max-age: 600

2. 白名單

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: ingress-myapp
  namespace: default
  annotations:
    kubernetes.io/ingress.class: "nginx"
    # 白名單
    nginx.ingress.kubernetes.io/whitelist-source-range: 120.176.65.13,120.79.18.35

# 設(shè)置從代理服務(wù)器讀取響應(yīng)的超時時間（以秒為單位，默認(rèn)值60）
nginx.ingress.kubernetes.io/proxy-read-timeout: "300"

# 強(qiáng)制重定向到 HTTPS（即使 Ingress 未啟用 TLS)
nginx.ingress.kubernetes.io/force-ssl-redirect: "true"

3. 強(qiáng)制https

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: test-ingress
  annotations:
    nginx.ingress.kubernetes.io/rewrite-target: /
    nginx.ingress.kubernetes.io/force-ssl-redirect: "true"
    nginx.ingress.kubernetes.io/ssl-redirect: "true"
    nginx.ingress.kubernetes.io/preserve-trailing-slash: "true"
spec:
  rules:
  - http:
      paths:
      - path: /testpath
        backend:
          serviceName: test
          servicePort: 80

4. 跳轉(zhuǎn)

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: test-ingress
  namespace: uf
  annotations:
    nginx.ingress.kubernetes.io/rewrite-target: /$1
spec:
  ingressClassName: nginx-ingress
  rules:
  - host: dev-gf.uf.net.cn
    http:
      paths:
      - backend:
          service:
            name: uf-epi-html
            port:
              number: 80
        path: /epi/(.*)
        pathType: ImplementationSpecific
