下载nginx镜像
docker pull docker.io/nginx:latest
由于calico网络不支持http协议，所以即使你在iptables中配置了nat路由，将访问宿主机80端口的请求都转发到nginx-consul-template，外部也无法访问nginx-ingress。于是我们需要额外启动一个nginx(docker host网络)，来做反向代理到nginx-ingress。
另如果你需要不同网卡下面的网络通讯的话，你只需要在iptables中添加NAT条目即可：
配置nginx
mkdir -p /opt/platform/nginx-host && cd /opt/platform/nginx-host && mkdir -p conf/conf.d modules html logs
vim /opt/platform/nginx-host/conf/conf.d/default.conf
upstream nginx-calico {
server 10.233.2.1:80;
server 10.233.3.1:80;
server 10.233.4.1:80;
}
server {
listen 80;
charset utf-8;
server_name *.test.com;
location / {
proxy_pass http://nginx-calico;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

proxy_send_timeout 150s;
proxy_read_timeout 150s;
proxy_next_upstream error timeout invalid_header http_404 http_502 http_504 http_500;
}
}

运行nginx-host
docker run -d --net=host -v /opt/platform/nginx-host/conf:/etc/nginx -v /opt/platform/nginx-host/modules:/usr/lib/nginx/modules -v /opt/platform/nginx-host/html:/usr/share/nginx/html -v /opt/platform/nginx-host/logs:/var/log/nginx --name=nginx-host nginx
