Kubernetes/K8S基础使用方法总结【六】——Ingress Controller

Ingress Controller安装官方说明文档。

对于裸机即虚拟机可以使用如下方法创建资源：

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-0.32.0/deploy/static/provider/baremetal/deploy.yaml

提示：

若无法下载可能是国内网络访问外global网部分限制的原因，笔者实在其他linux服务器下载deploy.yaml文件和相关镜像导入后使用的，如果需要可以关注微信公众号“琼杰笔记”，回复“ingress”免费获取。

wget https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-0.32.0/deploy/static/provider/baremetal/deploy.yaml

通过yaml清单创建ingress资源：

apiVersion: v1
kind: Service
metadata:
  name: myapp
  namespace: default
spec:
  selector:
    app: myapp
    release: canary
  ports:
  - name: http
    targetPort: 80
    port: 80
---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: myapp-deploy
  namespace: default
spec:
  replicas: 3
  selector:
    matchLabels:
      app: myapp
      release: canary
  template:
    metadata:
      labels:
        app: myapp
        release: canary
    spec:
      containers:
      - name: myapp
        image: ikubernetes/myapp:v2
        ports:
        - name: http
          containerPort: 80
