Getting Docker

Docker Community Edition

macOS and Windows 10 users can download a Docker Community Edition (CE) installer from:

• https://store.docker.com/editions/community/docker-ce-desktop-mac
• https://store.docker.com/editions/community/docker-ce-desktop-windows

Registration is required and can be done at https://store.docker.com/signup

Users of older operating systems may be able to use Docker Toolbox instead:

• https://docs.docker.com/toolbox/toolbox_install_mac/
• https://docs.docker.com/toolbox/toolbox_install_windows/

Docker on Linux

Digital Ocean has some excellent guides for installing Docker on Linux:

• https://www.digitalocean.com/community/tutorials/how-to-install-and-use-docker-on-ubuntu-18-04
• https://www.digitalocean.com/community/tutorials/how-to-install-and-use-docker-on-ubuntu-16-04
• https://www.digitalocean.com/community/tutorials/how-to-install-and-use-docker-on-centos-7
• https://www.digitalocean.com/community/tutorials/how-to-install-and-use-docker-on-debian-9

Linux users should note that docker-compose is required, but may not be installed automatically by following the guides above. On Ubuntu/Debian, after following the appropriate guide above, you can run:

sudo apt install docker-compose

Testing your Docker installation

Depending on your operating system and the way you install Docker, you may need to manually launch the Docker application / service after installation, before being able to run docker commands.

Try running pulling and running Docker’s hello-world image:

$ docker run hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
