docker-compose + nginx 实现 简单灰度 (
image本来是我本地自己构建的镜像tomcat:1.0,我推送到阿里云去了: registry.cn-hangzhou.aliyuncs.com/wuy2009123/tomcat8-1
docker-compose.yml 内容:
version: '3'
services:
myjava1:

- /root/tom/java-docker-compose/index1.html:/usr/local/tomcat8/webapps/ROOT/index.html
command: ["catalina.sh","run"]
networks:

myjava2:
image: registry.cn-hangzhou.aliyuncs.com/wuy2009123/tomcat8-1
container_name: myjava2

下一篇我会把 nginx换成 openresty , 基于 ip判断会换成从redis中读取,未完,待续!
