Well, this would be true if we simply ran the container without using the publish option. So, although our containers can get out onto the web, no incoming traffic can reach our containers. The firewall on your host machine, by default, blocks all incoming traffic. This bridge network is automatically attached to the ethernet interface of your host machine so that containers can reach the larger network.

When you start a new container and do not specify a network, it is attached to this virtual network.

So what is going on here?Дocker has a default virtual network called the bridge network (identified as docker0). You should be able to see that the IP address of your container is not the same as your host machine. You can re use this command with format option to pull any information from a Docker inspect output but in this case we want the IP address from the network settings.Дocker container inspect -format '' testwebhost You could simply run docker container inspect and search through the output for the IP address. We can test this using a Docker inspect command. What about the containerвЂ™s IP address? You may think that containers use the same IP address as the host machine but that is not the case. You should now see that port 80 of your host is forwarding traffic to port 80 of the container. We can now list our port mappings for that container using: LetвЂ™s start off with a basic Docker command to run an nginx:apline web server container and forward traffic from port 80 of our host machine into port 80 of our container:Дocker container run -p 80:80 -name testwebhost -d nginx:alpine

Some basic understanding of networking (Nice to have, but not required).

In this blog post, we are going to dive into Docker networking and see what is going on in the background and why it is important. Docker utilizes a вЂњbatteries included, but replaceableвЂќ architecture meaning that the default network your containers connect to works well in many cases but can also be replaced with a custom network. When you start a container, you are also connecting to a specific Docker network. Well, if cavemen had computers of course.

I think the issue is that it is simply not possible to do this (connect directly to the private IP of a Docker container from the host) when using Docker for Windows (or for Mac as a matter of fact) and that it only works in containers running in Docker for Linux.Spinning up a Docker container is so simple that a caveman could do it.

I started a container using VS Code Remote Container extension and from a network perspective it looks pretty much the same with a normal container started in the default bridge network. For the limited use case I have, I want to be able to ping the IP of the container for example or to connect to one of its ports directly using its private IP. My impression is that VS Code is attaching to containers and then you can expose ports on the local host when needed, but it does not connect to the IP address of the Docker container.

ping IP from Ubuntu WSL2 and expect a those are some really cool extensions and features that I had no idea about! Clarification question: when you say running and connecting to the demo server, what do you mean? What steps did you do to achieve that?.

Get its private IP using docker container inspect id.

Run a Docker container from Ubuntu WSL2 and keep it running.

I have tried to do this on Winwith WSL2 and Docker Desktop with WSL2 backend 2.3.0.1, from a Ubuntu 20.04 running in WSL2, but it doesn't work in the 'default' setup.

I find it useful when using Kubernetes in Docker in WSL and to be able to connect to the 'nodes' IPs directly.

I know there are many things that are different in the setup with Ubuntu in WSL2 and Docker Desktop for Windows Edge with WSL2 backend, but I am wondering if there is any way to access containers using their IP in this setup? If not, what is preventing that from happening? Is it a design decision or a bug or configuration?ДЄs far as I know, accessing containers by private IP is not encouraged or an advertised feature, so I know what I'm asking here is rather 'niche'. In 'normal' Ubuntu with Docker, you can access containers using their IP (that you determine from 'docker container inspect id').
