How To Install “ip addr” Command on Ubuntu Using Apt in Docker

Ubuntu 15

In this article, we will guide you through the process of installing the “ip addr” command on Ubuntu using Apt in Docker. The “ip addr” command is part of the “iproute2” package, which is a dependency for many network-related tasks in Linux.

Quick Answer

To install the "ip addr" command on Ubuntu using Apt in Docker, you need to create a Dockerfile that installs the "iproute2" package. Build a Docker image from the Dockerfile and run a Docker container from the image. Once inside the container, you can use the "ip addr" command.

What is “ip addr” Command?

The “ip addr” command is used in Linux to display or manipulate routing, devices, policy routing, and tunnels. It is part of the “iproute2” utility package, which is a collection of utilities for controlling TCP/IP networking and traffic control in Linux.

Setting Up Docker

Before we proceed with the installation, make sure that Docker is installed and running on your machine. If not, you can follow the official Docker installation guide.

Creating a Dockerfile

A Dockerfile is a text document that contains all the commands a user could call on the command line to assemble an image. In our case, we need to create a Dockerfile that will install the “iproute2” package.

Here’s how to do it:

FROM ubuntu:latest
RUN apt-get update && apt-get install -y iproute2

In the above Dockerfile:

  • FROM ubuntu:latest specifies that we are using the latest Ubuntu image as our base image.
  • RUN apt-get update && apt-get install -y iproute2 is a command that updates the package lists and then installs the “iproute2” package. The -y option is used to automatically say yes to the prompts during the installation.

Building the Docker Image

After creating the Dockerfile, you can build the Docker image using the following command:

docker build -t myubuntu .

In this command:

  • docker build is the command that builds Docker images from a Dockerfile and a “context”.
  • -t myubuntu is used to tag the image with a name. In this case, the name is “myubuntu”.
  • . specifies the Dockerfile location. In this case, the Dockerfile is in the current directory.

Running the Docker Container

Once the Docker image is built, you can run a Docker container from this image using the following command:

docker run -it myubuntu

In this command:

  • docker run is the command that runs a command in a new container.
  • -it option is used to run the container in interactive mode.
  • myubuntu is the name of the Docker image.

After running this command, you should be inside the Docker container. You can now use the “ip addr” command.


In this article, we have shown you how to install the “ip addr” command on Ubuntu using Apt in Docker. We hope this guide has been helpful. If you have any questions or run into any issues, feel free to ask in the comments section below.

What is Docker?

Docker is an open-source platform that allows you to automate the deployment, scaling, and management of applications using containerization. Containers are lightweight, isolated environments that package software and its dependencies, allowing for consistent and efficient deployment across different environments.

What is a Dockerfile?

A Dockerfile is a text document that contains all the commands and instructions needed to build a Docker image. It specifies the base image, adds any necessary dependencies, and configures the environment for running the application within the container.

How does the `FROM` command work in a Dockerfile?

The FROM command specifies the base image for the Docker image you are building. It determines the starting point for your image and provides the necessary operating system and environment. You can use official images from Docker Hub or create your own base image.

What does the `RUN` command do in a Dockerfile?

The RUN command is used to execute commands within the Docker image during the build process. It allows you to install packages, run scripts, or perform any other necessary tasks to set up the environment for your application.

How do I tag a Docker image?

You can tag a Docker image using the -t option followed by the desired tag name when running the docker build command. For example, docker build -t myimage:1.0 . will tag the image as myimage with the version 1.0.

How can I access the Docker container once it is running?

You can access the Docker container by running the docker exec -it [container_name] [command] command. This allows you to execute commands inside the running container. For example, docker exec -it mycontainer bash will open a bash shell inside the mycontainer container.

How can I remove a Docker image or container?

To remove a Docker image, you can use the docker rmi [image_name] command. For example, docker rmi myimage:1.0 will remove the myimage image with the version 1.0. To remove a Docker container, you can use the docker rm [container_name] command. For example, docker rm mycontainer will remove the mycontainer container.

Can I use the “ip addr” command outside of Docker?

Yes, the "ip addr" command is a standard Linux command and can be used on any Linux system, including outside of Docker. It is commonly used for network-related tasks such as displaying network interfaces, IP addresses, and routing information.
