I have used docker toolbox in the past on windows with Virtualbox and boot2docker. Now I installed new docker windows and boot2docker is not recognized anymore when typing
boot2docker ip
What command should I use now for Docker Windows ?
It should be localhost. Docker for Windows (as well as Docker for Mac) are doing some additional magic proxying to automatically forward ports from the host to the IP address of the VM so you shouldn't need to know the IP.
However, there are some caveats on Windows. Check out https://docs.docker.com/docker-for-windows/troubleshoot/#limitations-of-windows-containers-for-localhost-and-published-ports for more information if you are using Windows containers.

I have the following scenario:
Mac OS Catalina
Windows Virtual Machine running on VirtualBox
Docker for Mac (not docker-machine or Docker Toolbox)
I need to access a port that is exposed with docker run -p 80:80 nginx from the Windows VM and nothing seems to work. I tried NAT, bridge, socat... any hints?
Ah, I figured it out.
I can access the docker service by using the bridge interface IP (but not using localhost).
So in essence:
VM in VirtualBox should run in network bridged mode
use http://1.2.3.4 in the browser where 1.2.3.4 is your MacOS network interface IP address
I have an Ubuntu host with a web app running inside a docker container.
The web app is accessible from Ubuntu PC via 172.19.0.XXX:8080.
Now I want to test how web app looks like in IE. For that I started VirtualBox with Win7.
How could I call web app from VM?
Already tried different VM network variants, such as default NAT with port forwarding; and bridge - without any luck
Thanks in advance!
You can map the ports between the docker container and the Ubuntu host when starting the container by using -p 8080:8080, then you should be able to connect from Ubuntu using localhost:8080
Once you do that, find the IP address of the Ubuntu host by running ifconfig and use that IP to connect from the Windows VM via http://<Ubuntu-ip>:8080
How does port forwarding work with docker-machine?
I recently installed the docker toolkit and spun up a container. However I cannot reach it on my local mac as.
Is this Port forwarding in docker-machine? using VBoxManage the best way to access the running docker container using my OSX browser?
To add port forwards from the command line to a running boot2docker VM use the following command:
VBoxManage controlvm boot2docker-vm natpf1 "default,tcp,127.0.0.1,1234,,1234"
After restarting kitematic & the docker-host default VM. The container appeared in kitematic and the bound URL.
I use Debian Jessie as a VirtualBox host.
I have a Windows 7 virtual machine guest, what I use for development purposes.
I want to install docker.
In order to install docker for Windows I need Boot2docker.exe.
Boot2docker itself is a VirtualBox virual machine.
It requires enable VT-x.
That doesn't seem to work.
VirtualBox error message:
VT-x is not available (VERR_VMX_NO_VMX)
E_FAIL (0x80004005)

You want to run Docker client on your Windows development VM. Now you want to create a boot2docker linux VM inside the windows VM to run the docker deamon on. I think it's better to run the docker deamon on your Debian host system and let the docker client talk to the host system.
See
https://docs.docker.com/engine/docker-overview/#the-docker-client
I've noticed that boot2docker runs docker on a VM as a deamon on port 2375.
Then I use local Mac OS X 'docker' command and it executes all calls on VM.
These are the commands I use:
boot2docker start
export DOCKER_HOST=tcp://:2375
And then 'docker images' (for example) is running on VM.
How can I do the same with a physical machine rather then VM?
boot2docker is meant to be for dev purpose. It will spawn a VM. For bare metal, simply install docker on the host and start the docker daemon with docker -d -H tcp://0.0.0.0:4243.
WARNING: This is very dangerous. Anyone will have root access to your host. In order to secure this, you should change 0.0.0.0 to 127.0.0.1 and either use a SSH tunnel or a nginx/apache frontend with authentification.
On you mac, then just export DOCKER_HOST=tcp://<host ip>:4243
