Install Redocly CLI

Choose the most appropriate installation method for your needs:

• Install locally, using npm or yarn to make the redocly command available on your system.
• Use npx to get the tool at runtime rather than installing it.
• The command is also available via Docker if you'd prefer to use it that way.

Install globally

:::success Tip Make sure you have the newest version of npm/yarn before you begin. :::

npm i -g @redocly/cli@latest

yarn global add @redocly/cli

Running redocly --version confirms that the installation was successful, and the currently-installed version of the tool.

Use npx at runtime

npx is npm's package runner. It installs and runs a command without installing it globally. You might use this where you can't install a new command, or in a CI context where the command is only used a handful of times.

npx @redocly/cli <command> [options]

npx @redocly/cli@latest lint petstore.yaml

Run commands inside Docker

Redocly CLI is available as a pre-built Docker image in Docker Hub and GitHub Packages.

Install Docker if you don't have it already, then pull the image with the following command:

docker pull redocly/cli

docker pull ghcr.io/redocly/cli

To give a Docker container access to your OpenAPI definition files, you need to mount the containing directory as a volume. Assuming the definition is in the current working directory, the command to use is:

docker run --rm -v $PWD:/spec redocly/cli lint petstore.yaml
