Assign a Static IP to a Docker Container

When a Docker container starts up, it gets a dynamic IP address by default. In this article, we will show you how to assign a static IP address to a specific Docker container.

Create a new Docker network:

$ docker network create --subnet=172.11.0.0/16 mycustomnetwork

You can run a docker container in this network with a specific (static) IP address:

$ docker run --net customnetwork --ip 172.11.0.11 -d container

To find out the current IP address assigned to the Docker container, run the command:

$ docker container inspect -f '{{ .NetworkSettings.IPAddress }}' CONTAINER_ID_OR_NAME

You can also set a static IP address in the docker-compose.yml file using the ipv4_address directive. For example:

$ sudo vim docker-compose.yml

version: '2'
services:
  webserver:
    image: nginx
    ports:
       - '8282:80'
    container_name: web-server
    networks:
      customnetwork:
        ipv4_address: 172.12.0.11
networks:
  mycustomnetwork2:
    ipam:
      config:
        - subnet: 172.12.0.0/16
