Docker provides a convenience script at get. The convenience script is not recommended for production environments, but can beused as an example to create a provisioning script that is tailored to your needs.
Also refer to the install using the repositorysteps to learn about installation steps to install using the package repository. The source code for the script is open source, and can be found in the docker-install repository on GitHub. Always examine scripts downloaded from the internet before running them locally. Before installing, make yourself familiar with potential risks and limitationsof the convenience script:. This example downloads the script from get. Docker is installed.
The docker service starts automatically on Debian baseddistributions. As the message indicates, non-root users cannot run Docker commands by default. The installation script requires root or sudo privileges to install anduse Docker. If you want to grant non-root users access to Docker, refer to thepost-installation steps for Linux.

Docker also provides a convenience script at test. This script is equivalent to thescript at get. Use this script toget early access to new releases, and to evaluate them in a testing environmentbefore they are released as stable.
If you installed Docker using the convenience script, you should upgrade Dockerusing your package manager directly. There is no advantage to re-running theconvenience script, and it can cause issues if it attempts to re-addrepositories which have already been added to the host machine.
