DOCKER 给运行中的容器添加映射端口
方法1
1、获得容器IP
将
container_name换成实际环境中的容器名
|
1
|
docker inspect `container_name` |
grep
IPAddress1
|
2、 iptable转发端口
将容器的8000端口映射到docker主机的8001端口
|
1
|
iptables -t nat -A DOCKER -p tcp --dport 8001 -j DNAT --to-destination 172.17.0.19:800012
|
方法2
1.提交一个运行中的容器为镜像
|
1
|
docker commit -m
'add images'
mycentos linjie
/mycentos
:v1
|
2.运行镜像并添加端口
|
1
|
docker run -d -p 8000:80 linjie
/mycentos
:v1
/bin/bash
