Docker port forwarding not working
I have setup Docker container for access my machine docker container to another machine in local.
Create a container below command:
docker run -it -d --name containerName -h www.myhost.net -v /var/www/html -p 7000:8000 --net mynetwork --ip 172.11.0.10 --privileged myimagename bash
After Create A Container Details:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
1e1e5e9b74b4 myimgaename "bash" 21 minutes ago Up 6 minutes 0.0.0.0:7000->8000/tcp containername
NetWork Details:
"NetworkSettings": {
"Bridge": "",
"SandboxID": "fe357c54c816fff0f9d642037dc9a173be7f7e42a80776d006572f6a1395969e",
"HairpinMode": false,

"LinkLocalIPv6PrefixLen": 0,
"Ports": {
"8000/tcp": [
{
"HostIp": "0.0.0.0",
"HostPort": "7000"
}
]
}
if I access docker ipaddr(172.11.0.10) or hostname(www.myhost.net) in mymachine(hostmachine) it working
But if I access with Port doesn't work: hostmachine ip: 192.168.1.1
go to the browser 192.168.1.1:7000 hostmachine and locally connected anoter machine also.
But My 7000 port are listen in hostmachine:
# ps aux | grep 7000

Suggest me Why Cannot access my Container to another machine. How to Resolve this Problem
A very common problem can be this:
Bind your app inside Docker to 0.0.0.0, not to 127.0.0.1 address to let Docker reach the app inside container.
Port 7000
on the host is redirecting to port 8000
in the container, but is anything listening on that port in the container?
Your docker run
command is a bit odd: -it
is for running a container interactively with a terminal attached; -d
is for running detached, in the background; bash
at the end overrides whatever the image configures as the startup command, which is why I think there's nothing listening on port 8000
.
Try running the simplest NGINX container with this:
docker run -d -p 8081:80 nginx:alpine
And then verify you can get to the homepage:
curl http://localhost:8081
If that's working then I'd look at how you're running your image.
