Docker port forwarding not working

Question

I have setup Docker container for access my machine docker container to another machine in local.

Create a container below command:

    docker run -i         


        

Answer 1

This was happening for me w/ Docker for Mac. Clicking the Docker icon, then Restart did the trick.

Answer 2

When i encountered this problem (with a docker-compose managed set of docker instances), I found that deleting the network that docker-compose fixed the problem:

docker-compose stop
# find the network related to my docker-compose setup
docker network ls
docker network rm NETWORKNAME
# let docker-compose recreate the network:
docker-compose up -d

Answer 3

Partial Answer:

Now I solved this problem partially, While i try without bash in create a container and change my port to 3000(-p 3000:80) it worked for me.

Before Command:

     docker run -it -d --name containerName -h www.myhost.net -v /var/www/html -p 3000:80 --net mynetwork --ip 172.11.0.10 --privileged myimagename  bash

After Command:

    docker run -it -d --name containerName -h www.myhost.net -v /var/www/html -p 3000:80 --net mynetwork --ip 172.11.0.10 --privileged myimagename

Then,

execute the container with bin/bash

  docker exec -it containerName bin/bash

Now , works locally Connected Another machine.

 hostmachineip:3000 


I don't know docker have any port restrictions.But This solution works for me.

Answer 4

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.

Answer 5

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.
