• 一：kubernetes 的 ingress

一：kubernetes 的 nginx ingress

1.1 ingress-nginx的部署

Ingress-Nginx github 地址：https://github.com/kubernetes/ingress-nginx
Ingress-Nginx 官方网站：https://kubernetes.github.io/ingress-nginx/

部署：

wget https://raw.githubusercontent.com/kubernetes/ingress-nginx/nginx-0.30.0/deploy/static/mandatory.yaml

wget https://raw.githubusercontent.com/kubernetes/ingress-nginx/nginx-0.30.0/deploy/static/provider/baremetal/service-nodeport.yaml

kubectl apply -f mandatory.yaml

kubectl apply -f service-nodeport.yaml

----

所有节点上传ingress-contro.tar 文件

所有节点加载镜像
docker load -i ingree.contro.tar

docker images

kubectl apply -f mandatory.yaml

kubectl get deploy -n ingress-nginx
kubectl get pod -n ingress-nginx

如何使用国外机器打包镜像已经下载

先部署docker

yum install -y yum-utils device-mapper-persistent-data lvm2

yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

yum install docker-ce-18.09.9 docker-ce-cli-18.09.9 containerd.io -y

service docker start

----

docker pull quay.io/kubernetes-ingress-controller/nginx-ingress-controller:0.30.0

docker save -o ingrss.contro.tar quay.io/kubernetes-ingress-controller/nginx-ingress-controller:0.30.0

tar -zcvf ingrss.contro.tar.gz ingrss.contro.tar

然后 下载 ingrss.contro.tar.gz 即可

部署ingress-nginx的 svc

wget https://raw.githubusercontent.com/kubernetes/ingress-nginx/nginx-0.30.0/deploy/static/provider/baremetal/service-nodeport.yaml

kubectl apply -f service-nodeport.yaml

kubectl get svc -n ingress-nignx

1.2：Ingress HTTP 代理访问

deployment、Service、Ingress Yaml 文件

---

---

kubectl apply -f nginx-ingress.yaml

kubectl get svc -n ingress-nginx

实现一个虚拟主机

定义deploy1 与svc1

kubectl apply -f deployment1.yaml

定义deploy2 与svc2

vim deployment2.yaml

spec:
replicas: 2
template:
metadata:
labels:

spec:
ports:
- port: 80
targetPort: 80
protocol: TCP
selector:

---
kubectl apply -f deployment2.yaml

定义ingress的nginx 对外连接

vim ingress.yaml
---

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: ingress1
spec:
rules:
- host: www1.flyfish.com
http:
paths:
- path: /
backend:
serviceName: svc-1
servicePort: 80
---
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: ingress2
spec:
rules:
- host: www2.flyfish.com
http:
paths:
- path: /
backend:
serviceName: svc-2
servicePort: 80
---

kubectl apply -f ingress.yaml

测试：

kubectl get svc

kubectl get svc -n ingress-nginx

1.3 Ingress HTTPS 代理访问

创建证书，以及 cert 存储方式

openssl req -x509 -sha256 -nodes -days 365 -newkey rsa:2048 -keyout tls.key -out tls.crt -subj "/CN=nginxsvc/O=nginxsvc"

kubectl create secret tls tls-secret --key tls.key --cert tls.crt
