kubernetes 的 ingress 配置部署
標籤（空格分隔）： kubernetes系列
- 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 官方網站：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
----
所有節點上傳ingress-contro.tar 文件
所有節點加載鏡像
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 
如何使用國外機器打包鏡像已經下載
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
然後 下載 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 代理訪問

kubectl get svc -n ingress-nginx
1.3 Ingress HTTPS 代理訪問
創建證書，以及 cert 存儲方式
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
