我正在尝试在docker内部运行apache2,但是当我公开端口时,只能从主机访问该服务,而不能从外部访问。
我通过以下方式执行了容器:
docker run -d -t -p 8080:80 --name ctf ubuntu
之后,我在里面安装了apache2:
apt-get update && apt-get install apache2 -y && service apache2 start
运行docker ps
时,我将得到:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
c90b8ed41436 ubuntu "/bin/bash" 3 minutes ago Up 3 minutes 0.0.0.0:8080->80/tcp ctf
我可以通过wget <public ip>:8080
从该主机访问该服务。但是,如果我尝试从同一网络上的其他设备运行,则无法正常工作。该服务无法访问。
命令iptables --list
也会产生:
Chain INPUT (policy ACCEPT)
target prot opt source destination
ACCEPT udp -- anywhere anywhere udp dpt:openvpn
Chain FORWARD (policy ACCEPT)
target prot opt source destination
DOCKER-USER all -- anywhere anywhere
DOCKER-ISOLATION-STAGE-1 all -- anywhere anywhere
ACCEPT all -- anywhere anywhere ctstate RELATED,ESTABLISHED
DOCKER all -- anywhere anywhere
ACCEPT all -- anywhere anywhere
ACCEPT all -- anywhere anywhere
ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED
ACCEPT all -- 10.8.0.0/24 anywhere
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
Chain DOCKER (1 references)
target prot opt source destination
ACCEPT tcp -- anywhere 172.17.0.2 tcp dpt:http
Chain DOCKER-ISOLATION-STAGE-1 (1 references)
target prot opt source destination
DOCKER-ISOLATION-STAGE-2 all -- anywhere anywhere
RETURN all -- anywhere anywhere
您知道问题出在哪里吗?
EDIT2:
netstat -ntlp
的结果似乎是docker没有将套接字绑定到IPv4:

但这不应成为问题,因为:
root@ubuntu:~/docker# sysctl net.ipv6.bindv6only
net.ipv6.bindv6only = 0
root@ubuntu:~/docker# sysctl net.ipv6.conf.all.forwarding
net.ipv6.conf.all.forwarding = 1
答案 0 :(得分:0)
问题是,在当前的wifi上,端口8080已被过滤:(对不起
