Docker Desktop provides several networking features to make it easier touse.

Features

VPN Passthrough

Docker Desktop networking can work when attached to a VPN. To do this,Docker Desktop intercepts traffic from the containers and injects it intoWindows as if it originated from the Docker application.

Port Mapping

Docker Desktop For Windows Server 2012

When you run a container with the -p argument, for example:

Switch between Windows and Linux containers describes how you can toggle between Linux and Windows containers in Docker Desktop and points you to the tutorial mentioned above. Getting Started with Windows Containers (Lab) provides a tutorial on how to set up and run Windows containers on Windows 10, Windows Server 2016 and Windows Server 2019. Docker Desktop provides an installation wizard, a management UI, and several other utilities for improving deployment. Docker Desktop is supported on Windows 10 and Mac. Docker Desktop comes with the Docker Engine CE or EE depending on the product tier we choose. Docker targets its enterprise product suite toward production environments. Docker Desktop for Windows. Pantonis (Pantonis) November 2, 2016, 7:58pm #1. Hi, I wanted to ask if Docker is compatible with windows server 2012 r2. To install docker on Windows Server 2016, you need to run few commands, and you will get things ready for your containerization world. I will share with you the installation steps and some docker. Start Docker Desktop Tool. After the installation process is complete, the tool does not start automatically. To start the Docker tool, search for the tool, and select Docker Desktop in your desktop search results. Before starting the application, Docker offers an onboarding tutorial. The tutorial explains how to build a Docker image and run a.

Docker Desktop makes whatever is running on port 80 in the container (inthis case, nginx) available on port 80 of localhost. In this example, thehost and container ports are the same. What if you need to specify a differenthost port? If, for example, you already have something running on port 80 ofyour host machine, you can connect the container to a different port:

Now, connections to localhost:8000 are sent to port 80 in the container. Thesyntax for -p is HOST_PORT:CLIENT_PORT.

HTTP/HTTPS Proxy Support

Known limitations, use cases, and workarounds

Following is a summary of current limitations on the Docker Desktop for Windowsnetworking stack, along with some ideas for workarounds.

There is no docker0 bridge on Windows

Because of the way networking is implemented in Docker Desktop for Windows, you cannotsee a docker0 interface on the host. This interface is actually within thevirtual machine.

I cannot ping my containers

Docker Desktop for Windows can’t route traffic to Linux containers. However, you canping the Windows containers.

Per-container IP addressing is not possible

The docker (Linux) bridge network is not reachable from the Windows host.However, it works with Windows containers.

Use cases and workarounds

There are two scenarios that the above limitations affect:

I want to connect from a container to a service on the host

The host has a changing IP address (or none if you have no network access). We recommend that you connect to the special DNS namehost.docker.internal which resolves to the internal IP address used by thehost. This is for development purpose and will not work in a production environment outside of Docker Desktop for Windows.

You can also reach the gateway using gateway.docker.internal.

If you have installed Python on your machine, use the following instructions as an example to connect from a container to a service on the host:

1. Run the following command to start a simple HTTP server on port 8000.

   python -m http.server 8000

   If you have installed Python 2.x, run python -m SimpleHTTPServer 8000.

2. Now, run a container, install curl, and try to connect to the host using the following commands:

I want to connect to a container from Windows

Port forwarding works for localhost; --publish, -p, or -P all work.Ports exposed from Linux are forwarded to the host.

Our current recommendation is to publish a port, or to connect from anothercontainer. This is what you need to do even on Linux if the container is on anoverlay network, not a bridge network, as these are not routed.

For example, to run an nginx webserver:

To clarify the syntax, the following two commands both publish container’s port 80 to host’s port 8000:

To publish all ports, use the -P flag. For example, the following commandstarts a container (in detached mode) and the -P flag publishes all exposed ports of thecontainer to random ports on the host.

See the run command for more details onpublish options used with docker run.
