Welcome to our guide on how to install Docker and Docker Compose on Kali Linux. We’ll install the Docker CE (Community Edition) on Kali Linux. Docker is the most popular and widely used container runtime. It enables Developers to package, ship and run their applications in isolated containers. Making it easy to ship from Developer machine to Production environment orchestrated with Kubernetes.
Below are commonly used terminologies in Docker ecosystem.
- Docker daemon: This is also called Docker Engine, it is a background process which runs on the host system responsible for building and running of containers.
- Docker Client: This is a command line tool used by the user to interact with the Docker daemon.
- Docker Image: An image is an immutable file that’s essentially a snapshot of a container. A docker image has a file system and application dependencies required for running applications.
- Docker container: This is a running instance of a docker image with an application and its dependencies. Each container has a unique process ID and isolated from other containers. The only thing containers share is the Kernel.
- Docker registry: This is an application responsible for managing storage and delivery of Docker container images. It can be private or public.
So let’s get started with the installation of Docker on Kali Linux.
Step 1: Install Dependency packages
Start the installation by ensuring that all the packages used by docker as dependencies are installed.
sudo apt update sudo apt -y install curl gnupg2 apt-transport-https software-properties-common ca-certificates
Step 2: Import Docker GPG key:
Import Docker GPG key used for signing Docker packages:
curl -fsSL https://download.docker.com/linux/debian/gpg | sudo apt-key add -
Step 3: Add the Docker repository to Kali Linux
Add Docker repository which contain the latest stable releases of Docker CE.
echo "deb [arch=amd64] https://download.docker.com/linux/debian buster stable" | sudo tee /etc/apt/sources.list.d/docker.list
This command will add repository URL to /etc/apt/sources.list.d/docker.list.
Step 4: Install Docker on Kali Linux
apt package index.
$ sudo apt update gn:1 http://dl.google.com/linux/chrome/deb stable InRelease Get:3 https://download.docker.com/linux/debian buster InRelease [44.4 kB] Hit:2 http://kali.download/kali kali-rolling InRelease Hit:4 http://dl.google.com/linux/chrome/deb stable Release Get:5 https://download.docker.com/linux/debian buster/stable amd64 Packages [10.9 kB] Fetched 55.3 kB in 1s (45.2 kB/s) Reading package lists... Done Building dependency tree Reading state information... Done 186 packages can be upgraded. Run 'apt list --upgradable' to see them.
To install Docker CE on Kali Linux, run the command:
sudo apt install docker-ce docker-ce-cli containerd.io
Hit the y key to start installation of Docker on Kali Linux.

This installation will add
docker group to the system without any users. Add your user account to the group to run docker commands as non-privileged user.
sudo usermod -aG docker $USER newgrp docker
Check Docker version installed.
$ docker version Client: Docker Engine - Community Version: 19.03.6 API version: 1.40 Go version: go1.12.16 Git commit: 369ce74a3c Built: Thu Feb 13 01:27:58 2020 OS/Arch: linux/amd64 Experimental: false Server: Docker Engine - Community Engine: Version: 19.03.6 API version: 1.40 (minimum version 1.12) Go version: go1.12.16 Git commit: 369ce74a3c Built: Thu Feb 13 01:26:32 2020 OS/Arch: linux/amd64 Experimental: false containerd: Version: 1.2.12 GitCommit: 35bd7a5f69c13e1563af8a93431411cd9ecf5021 runc: Version: 1.0.0-rc10 GitCommit: dc9208a3303feef5b3839f4323d9beb36df0a9dd docker-init: Version: 0.18.0 GitCommit: fec3683
Step 5: Install Docker Compose on Kali Linux
Use the guide below to install latest Docker Compose on Kali Linux.
After installation, confirm successful installation by checking version.
$ docker-compose version docker-compose version 1.25.4, build 8d51620a docker-py version: 4.1.0 CPython version: 3.7.5 OpenSSL version: OpenSSL 1.1.0l 10 Sep 2019
Step 6: Test Docker installation.
Run a test docker container:
$ docker run --rm -it hello-world Unable to find image 'hello-world:latest' locally latest: Pulling from library/hello-world 1b930d010525: Pull complete Digest: sha256:9572f7cdcee8591948c2963463447a53466950b3fc15a247fcad1917ca215a2f Status: Downloaded newer image for hello-world:latest Hello from Docker! This message shows that your installation appears to be working correctly. To generate this message, Docker took the following steps: 1. The Docker client contacted the Docker daemon. 2. The Docker daemon pulled the "hello-world" image from the Docker Hub. (amd64) 3. The Docker daemon created a new container from that image which runs the executable that produces the output you are currently reading. 4. The Docker daemon streamed that output to the Docker client, which sent it to your terminal. To try something more ambitious, you can run an Ubuntu container with: $ docker run -it ubuntu bash Share images, automate workflows, and more with a free Docker ID: https://hub.docker.com/ For more examples and ideas, visit: https://docs.docker.com/get-started/
Step 6: Test Docker Compose installation.
Create a test Docker Compose file.
$ vim docker-compose.yml
Add below data to the file.
version: '3' services: web: image: nginx:latest ports: - "8080:80" links: - php php: image: php:7-fpm
Start service containers.
$ docker-compose up -d Creating network "jkmutai_default" with the default driver Pulling php (php:7-fpm)... 7-fpm: Pulling from library/php bc51dd8edc1b: Pull complete a3224e2c3a89: Pull complete be7a066df88f: Pull complete bfdf741d72a9: Pull complete 0096578ff21c: Pull complete 52b9a3846c51: Pull complete 91c8df69c5cf: Pull complete ba16a1822680: Pull complete c137b651214d: Pull complete a2738b6c9bea: Pull complete Digest: sha256:022dcc4f1a054584660ce3d77bb0dc1f5084d25f117d4814726518b7f66af47f Status: Downloaded newer image for php:7-fpm Pulling web (nginx:latest)... latest: Pulling from library/nginx bc51dd8edc1b: Already exists 66ba67045f57: Pull complete bf317aa10aa5: Pull complete Digest: sha256:ad5552c786f128e389a0263104ae39f3d3c7895579d45ae716f528185b36bc6f Status: Downloaded newer image for nginx:latest Creating jkmutai_php_1 ... done Creating jkmutai_web_1 ... done
