Ever felt tangled in the complexities of Docker networks and Docker-Compose? Docker networks and Docker-Compose are integral to containerization. Docker networks serve as the communication channel for your Docker containers, enabling them to interact. Docker-Compose, on the other hand, is a tool for defining and running multi-container Docker applications. Our goal in this post is to offer a comprehensive guide on using Docker networks and Docker-Compose in real-life situations.

Effective July , Compose V1 stopped receiving updates and is no longer in new Docker Desktop releases. Compose V2 has replaced it and is now integrated into all current Docker Desktop versions. For more information, see Migrate to Compose V2. By default Compose sets up a single network for your app. Each container for a service joins the default network and is both reachable by other containers on that network, and discoverable by the service's name. Your app's network is given a name based on the "project name", which is based on the name of the directory it lives in. For example, suppose your app is in a directory called myapp , and your compose. Each container can now look up the service name web or db and get back the appropriate container's IP address. If you make a configuration change to a service and run docker compose up to update it, the old container is removed and the new one joins the network under a different IP address but the same name. Running containers can look up that name and connect to the new address, but the old address stops working. If any containers have connections open to the old container, they are closed.

Specify a driver for networks. Docker on Mac has… Read more.

In my previous article on docker networks , I touched on the basics of network management using the docker CLI. But in real life, you probably won't work this way, and you will have all the containers needed to be orchestrated by a docker-compose file. This is where this article comes into play - let's see how to use networks in real life. Let's start with some very basic stuff, if you are already familiar with docker-compose you might want to skip some sections below.

The port is exposed on your network interface, not the container one.

One for service1, and a second one for service2. Microservices are often developed and deployed independently, leading to a complex network structure. Lean the fundamentals of the Kubernetes and Docker technologies and how they interplay with each other. Fully describing Pumba would take lots of time, so let's just have a look at a very simple network delay simulation. To use a driver for networks, you can specify the [.
