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?Īs 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". That's it for today.In "normal" Ubuntu with Docker, you can access containers using their IP (that you determine from "docker container inspect id"). ❯ docker network inspect -f ' else empty end'Ĭhange bridge to some other network, and you'll get all the containers and their IP addresses like this. I'm going to filter the output since for this demonstration I don't need all the data that inspect is going to explode out. You can get more details about this network by running the docker network inspect bridge command.
The bridge network is the default network every container is going to be connected to if none is specified explicitly. Ignore the last two and focus on the first network. You can get the list of networks using the following command docker network lsĬonsider my list below: ❯ docker network ls There are mainly two types of networks, the default or predefined networks and the user-defined networks. If two containers take on IP addresses from the same pool, they're going to be able to communicate with each other. Think of docker network as a pool of available IP addresses. This network is called a "docker network". This communication is achieved by having at least two network interfaces associated with each of these two containers, both interfaces being connected to the same network. The frontend has to communicate with the database, otherwise, it just won't work. There are two services, one is the web server that serves the frontend, and another is the backend, the database. Depending on the purpose of the software, one service may need to communicate with another.įor example, consider WordPress. Each of these softwares is broken down into microservices and then packaged as containers.

Software can have a multitude of purposes, from possibly simple text processing to a full web server, hosting your private files. How docker containers communicate?ĭocker is a tool for packaging and delivering software to the masses using containerization technology. I'll explain that to you in the next section followed by some other methods of getting the IP address of a running docker container. To understand that, you need to understand how containers communicate with each other. You may also use grep command to get just the lines matching the string "IPAddress".ĭon't be alarmed if your container has more than one IP address.
Go towards the end and look into the Networks section to get the container's IP address. The inspect command gives you many details about the container you are inspecting. Don't know the container's name or ID? Use the command sudo docker ps.
