Install Docker Scout

Table of contents

The Docker Scout CLI plugin comes pre-installed with Docker Desktop.

If you run Docker Engine without Docker Desktop, Docker Scout doesn't come pre-installed, but you can install it as a standalone binary.

Installation script

To install the latest version of the plugin, run the following commands:

$ curl -fsSL https://raw.githubusercontent.com/docker/scout-cli/main/install.sh -o install-scout.sh
$ sh install-scout.sh
Note

Always examine scripts downloaded from the internet before running them locally. Before installing, make yourself familiar with potential risks and limitations of the convenience script.
