Container is not available on localhost in Windows Docker Toolbox

I try to connect to my container on localhost/127.0.0.1/0.0.0.0 but site can’t be reached.

Details:

$ docker run -d -p 80:80 nginx:alpine

$ docker ps

I followed this tutotial: https://blog.sixeyed.com/published-ports-on-windows-containers-dont-do-loopback/:

$ docker inspect --format '{{ .NetworkSettings.Networks.nat.IPAddress }}' d5b465ed1b18
<no value>

but it doesn't return port.

And I also helped myself with this guide: https://www.iancollington.com/docker-and-cisco-anyconnect-vpn/ because some of my docker images are on private registry, so I did following steps:

  1. PATH=$PATH:"C:\Program Files\Oracle\VirtualBox"; export PATH
  2. export DOCKER_HOST="tcp://127.0.0.1:2376"
  3. docker-machine stop default
  4. VBoxManage modifyvm "default" --natpf1 "docker,tcp,,2376,,2376"
  5. docker-machine start default
  6. alias docker='docker --tlsverify=false'

Could you help?

Solution

  • When you are using Docker Toolbox, running docker run -p 80:80 can be misleading. It means it will forward the port 80 of your container to the port 80 of your Docker machine, not the Windows host!

    If you want to access the container through your Windows host, you also need to forward port 80 of your Docker machine to that host.

    I see you are using VirtualBox, which allows you to do that by adding an entry in Settings > Network > Advanced > Port Forwarding.
