Then, you can run a container, specifying the network with the -net flag, and specifying the IP with the -ip flag: docker run -net customnetwork -ip 172.20.0.10 -d container RELATED: What are Subnets, and How Do They Affect My Network? Setting Up Static IPsįirst, you’ll need to set up a Docker network, and since we care about the IP address, you’ll need to specify a fixed subnet: docker network create -subnet=172.20.0.0/16 customnetwork You’ll still need to use a custom Docker network to do so, but it’s easy to set up. However, there are still plenty of times when you’ll want to manually specify a private IP address, such as accessing containers directly from the host. To learn more, you can read Docker’s documentation on user-defined bridge networks. docker network create exampleĭocker run -net example -name nginx -d nginxĭocker network connect example -alias mongohost mongodb In most cases, Docker’s built in networking can handle this.ĭocker comes with a default network, but if you make your own, you can give containers aliases when launched in that network. This alias will resolve to the container’s private IP automatically. For example, the NGINX container here can access the MongoDB instance with the connection string mongodb://mongohost:27017. Most of the time, you’ll want a static IP to talk to one container from another, or from the host. If you want to make a static private IP address, you should consider if you need to use one at all. For example, binding port 80 (HTTP) on the host to point to an NGINX container: docker run -publish=80:8080 nginx While there are more advanced networking setups, this is by far the easiest and most common. You can “publish” ports on the Docker container to be accessible from the host. If you need to set up a public IP address for a container, you’ll want to use port bindings.

Knowing these, we will now see the different methods that can be used to find out the IP address of a docker container in a network.

The default subnet for a docker network is 172.17.0.0/16. There are two kinds of “static IP” private IP addresses used for internal networking inside a server, and public IP addresses used to connect outside the server, often over the internet. This also means that each container in the docker network is assigned an IP address. Assigning Docker containers static IP addresses is an easy way to make them more accessible. Static IP addresses don’t change when containers or services are stopped and started, making them useful for permanent networking. You’ll still need to use a custom Docker network to do so, but it’s easy to set up.
